Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. South America’s lush Amazon region is a biodiversity hotspot, which means that every living thing must find a way to co-exist. Even some of the most feared snakes on the planet–anacondas. In a paper published June 16 in the journal Frontiers in Amphibian and Reptile Science, conservation biologists Beatriz Cosendey and Juarez Carlos Brito Pezzuti from the Federal University of Pará’s Center for Amazonian Studies in Brazil, analyze the key points behind the interactions between humans and the local anaconda populations. Ahead of the paper’s publication, the team at Frontiers conducted this wide-ranging Q&A with Conesday. It has not been altered. Frontiers: What inspired you to become a researcher? Beatriz Cosendey: As a child, I was fascinated by reports and documentaries about field research and often wondered what it took to be there and what kind of knowledge was being produced. Later, as an ecologist, I felt the need for approaches that better connected scientific research with real-world contexts. I became especially interested in perspectives that viewed humans not as separate from nature, but as part of ecological systems. This led me to explore integrative methods that incorporate local and traditional knowledge, aiming to make research more relevant and accessible to the communities involved. F: Can you tell us about the research you’re currently working on? BC: My research focuses on ethnobiology, an interdisciplinary field intersecting ecology, conservation, and traditional knowledge. We investigate not only the biodiversity of an area but also the relationship local communities have with surrounding species, providing a better understanding of local dynamics and areas needing special attention for conservation. After all, no one knows a place better than those who have lived there for generations. This deep familiarity allows for early detection of changes or environmental shifts. Additionally, developing a collaborative project with residents generates greater engagement, as they recognize themselves as active contributors; and collective participation is essential for effective conservation. Local boating the Amazon River. CREDIT: Beatriz Cosendey. F: Could you tell us about one of the legends surrounding anacondas? BC: One of the greatest myths is about the Great Snake—a huge snake that is said to inhabit the Amazon River and sleep beneath the town. According to the dwellers, the Great Snake is an anaconda that has grown too large; its movements can shake the river’s waters, and its eyes look like fire in the darkness of night. People say anacondas can grow so big that they can swallow large animals—including humans or cattle—without difficulty. F: What could be the reasons why the traditional role of anacondas as a spiritual and mythological entity has changed? Do you think the fact that fewer anacondas have been seen in recent years contributes to their diminished importance as an mythological entity? BC: Not exactly. I believe the two are related, but not in a direct way. The mythology still exists, but among Aritapera dwellers, there’s a more practical, everyday concern—mainly the fear of losing their chickens. As a result, anacondas have come to be seen as stealthy thieves. These traits are mostly associated with smaller individuals (up to around 2–2.5 meters), while the larger ones—which may still carry the symbolic weight of the ‘Great Snake’—tend to retreat to more sheltered areas; because of the presence of houses, motorized boats, and general noise, they are now seen much less frequently. A giant anaconda is being measured. Credit: Pedro Calazans. F: Can you share some of the quotes you’ve collected in interviews that show the attitude of community members towards anacondas? How do chickens come into play? BC: When talking about anacondas, one thing always comes up: chickens. “Chicken is her [the anaconda’s] favorite dish. If one clucks, she comes,” said one dweller. This kind of remark helps explain why the conflict is often framed in economic terms. During the interviews and conversations with local dwellers, many emphasized the financial impact of losing their animals: “The biggest loss is that they keep taking chicks and chickens…” or “You raise the chicken—you can’t just let it be eaten for free, right?” For them, it’s a loss of investment, especially since corn, which is used as chicken feed, is expensive. As one person put it: “We spend time feeding and raising the birds, and then the snake comes and takes them.” One dweller shared that, in an attempt to prevent another loss, he killed the anaconda and removed the last chicken it had swallowed from its belly—”it was still fresh,” he said—and used it for his meal, cooking the chicken for lunch so it wouldn’t go to waste. One of the Amazonas communities where the researchers conducted their research. CREDIT: Beatriz Cosendey. Some interviewees reported that they had to rebuild their chicken coops and pigsties because too many anacondas were getting in. Participants would point out where the anaconda had entered and explained that they came in through gaps or cracks but couldn’t get out afterwards because they ‘tufavam’ — a local term referring to the snake’s body swelling after ingesting prey. We saw chicken coops made with mesh, with nylon, some that worked and some that didn’t. Guided by the locals’ insights, we concluded that the best solution to compensate for the gaps between the wooden slats is to line the coop with a fine nylon mesh (to block smaller animals), and on the outside, a layer of wire mesh, which protects the inner mesh and prevents the entry of larger animals. F: Are there any common misconceptions about this area of research? How would you address them? BC: Yes, very much. Although ethnobiology is an old science, it’s still underexplored and often misunderstood. In some fields, there are ongoing debates about the robustness and scientific validity of the field and related areas. This is largely because the findings don’t always rely only on hard statistical data. However, like any other scientific field, it follows standardized methodologies, and no result is accepted without proper grounding. What happens is that ethnobiology leans more toward the human sciences, placing human beings and traditional knowledge as key variables within its framework. To address these misconceptions, I believe it’s important to emphasize that ethnobiology produces solid and relevant knowledge—especially in the context of conservation and sustainable development. It offers insights that purely biological approaches might overlook and helps build bridges between science and society. The study focused on the várzea regions of the Lower Amazon River. CREDIT: Beatriz Cosendey. F: What are some of the areas of research you’d like to see tackled in the years ahead? BC: I’d like to see more conservation projects that include local communities as active participants rather than as passive observers. Incorporating their voices, perspectives, and needs not only makes initiatives more effective, but also more just. There is also great potential in recognizing and valuing traditional knowledge. Beyond its cultural significance, certain practices—such as the use of natural compounds—could become practical assets for other vulnerable regions. Once properly documented and understood, many of these approaches offer adaptable forms of environmental management and could help inform broader conservation strategies elsewhere. F: How has open science benefited the reach and impact of your research? BC: Open science is crucial for making research more accessible. By eliminating access barriers, it facilitates a broader exchange of knowledge—important especially for interdisciplinary research like mine which draws on multiple knowledge systems and gains value when shared widely. For scientific work, it ensures that knowledge reaches a wider audience, including practitioners and policymakers. This openness fosters dialogue across different sectors, making research more inclusive and encouraging greater collaboration among diverse groups. The Q&A can also be read here.

Why Sunset Colors Never Go Out of Style Before we explore how to use these palettes effectively, let’s talk about why sunset colors have such enduring appeal in design. There’s something deeply ingrained in human psychology that responds to these warm, glowing hues. They remind us of endings and beginnings, of peaceful moments and natural beauty. From a design perspective, sunset colors offer incredible versatility. They can be bold and energetic or soft and romantic. They work equally well for corporate branding and personal projects. And perhaps most importantly, they’re inherently optimistic – they make people feel good. I’ve found that incorporating sunset-inspired colors into modern projects adds an instant sense of warmth and approachability that resonates with audiences across all demographics. Whether you’re working on packaging design, web interfaces, or environmental graphics, these palettes can help create an emotional connection that goes beyond mere aesthetics. How to Master Sunset Palettes in Contemporary Design Using sunset colors effectively requires more than just picking pretty hues and hoping for the best. Here are some strategies I’ve developed for incorporating these palettes into modern design work: Start with Temperature Balance One of the most important aspects of working with sunset palettes is understanding color temperature. Most sunset combinations naturally include both warm and cool elements – the warm oranges and yellows of the sun itself, balanced by the cooler purples and blues of the surrounding sky. Maintaining this temperature balance keeps your designs from feeling flat or monotonous. Layer for Depth Real sunsets have incredible depth and dimension, with colors layering and blending into each other. Try to recreate this in your designs by using gradients, overlays, or layered elements rather than flat blocks of color. This approach creates visual interest and mimics the natural way these colors appear in nature. Consider Context and Contrast While sunset colors are beautiful, they need to work within the context of your overall design. Pay attention to readability – text needs sufficient contrast against sunset backgrounds. Consider using neutrals like deep charcoal or cream to provide breathing room and ensure your message remains clear. Embrace Gradual Transitions The magic of a sunset lies in how colors flow seamlessly from one to another. Incorporate this principle into your designs through smooth gradients, subtle color shifts, or elements that bridge between different hues in your palette. The Science Behind Our Sunset Obsession As someone who’s spent years studying color psychology, I’m fascinated by why sunset colors have such universal appeal. Research suggests that warm colors like those found in sunsets trigger positive emotional responses and can even increase feelings of comfort and security. There’s also the association factor – sunsets are linked in our minds with relaxation, beauty, and positive experiences. When we see these colors in design, we unconsciously associate them with those same positive feelings. This makes sunset palettes particularly effective for brands that want to create emotional connections with their audiences. The cyclical nature of sunsets also plays a role. They happen every day, marking the transition from activity to rest, from work to leisure. This gives sunset colors a sense of familiarity and comfort that few other color combinations can match. Applying Sunset Palettes Across Design Disciplines One of the things I love most about sunset color palettes is how adaptable they are across different types of design work: Brand Identity Design Sunset colors can help brands convey warmth, optimism, and approachability. I’ve used variations of these palettes for everything from artisanal food companies to wellness brands. The key is choosing the right intensity level for your brand’s personality – softer palettes for more refined brands, bolder combinations for companies that want to make a statement. Digital Design In web and app design, sunset colors can create interfaces that feel warm and inviting rather than cold and clinical. I often use these palettes for backgrounds, accent elements, or call-to-action buttons. The natural flow between colors makes them perfect for creating smooth user experiences that guide the eye naturally through content. Print and Packaging Sunset palettes really shine in print applications where you can take advantage of rich, saturated colors. They work beautifully for packaging design, particularly for products associated with warmth, comfort, or natural ingredients. The key is ensuring your color reproduction is accurate – sunset colors can look muddy if not handled properly in print. Environmental Design In spaces, sunset colors can create incredibly welcoming environments. I’ve seen these palettes used effectively in restaurants, retail spaces, and even corporate offices where the goal is to create a sense of warmth and community. Seasonal Considerations and Trending Applications While sunset colors are timeless, they do have natural seasonal associations that smart designers can leverage. The warmer, more intense sunset palettes work beautifully for fall and winter campaigns, while the softer, more pastel variations are perfect for spring and summer applications. I’ve noticed a growing trend toward using sunset palettes in unexpected contexts – tech companies embracing warm gradients, financial services using sunset colors to appear more approachable, and healthcare brands incorporating these hues to create more comforting environments. Conclusion: Bringing Natural Beauty Into Modern Design As we’ve explored these eight stunning sunset color palettes, I hope you’ve gained new appreciation for the incredible design potential that nature provides us every single day. These colors aren’t just beautiful – they’re powerful tools for creating emotional connections, conveying brand values, and making designs that truly resonate with people. The secret to successfully using sunset palettes lies in understanding both their emotional impact and their technical requirements. Don’t be afraid to experiment with different combinations and intensities, but always keep your audience and context in mind. Remember, the best sunset colors aren’t just about picking the prettiest hues – they’re about capturing the feeling of those magical moments when day transitions to night. Whether you’re creating a logo that needs to convey warmth and trust, designing a website that should feel welcoming and approachable, or developing packaging that needs to stand out on crowded shelves, these sunset-inspired palettes offer endless possibilities. So the next time you catch yourself stopped in your tracks by a particularly stunning sunset, take a moment to really study those colors. Notice how they blend and flow, how they make you feel, and how they change as the light shifts. Then bring that natural magic into your next design project. After all, if nature can create such breathtaking color combinations every single day, imagine what we can achieve when we learn from the master. Happy designing!

Barricades, as we know them today, are thought to date back to the European wars of religion. According to most historians, the first barricade went up in Paris in 1588; the word derives from the French barriques, or barrels, spontaneously put together. They have been assembled from the most diverse materials, from cobblestones, tyres, newspapers, dead horses and bags of ice (during Kyiv’s Euromaidan in 2013–14), to omnibuses and e‑scooters. Their tactical logic is close to that of guerrilla warfare: the authorities have to take the barricades in order to claim victory; all that those manning them have to do to prevail is to hold them.  The 19th century was the golden age for blocking narrow, labyrinthine streets. Paris had seen barricades go up nine times in the period before the Second Empire; during the July 1830 Revolution alone, 4,000 barricades had been erected (roughly one for every 200 Parisians). These barricades would not only stop, but also trap troops; people would then throw stones from windows or pour boiling water onto the streets. Georges‑Eugène Haussmann, Napoleon III’s prefect of Paris, famously created wide boulevards to make blocking by barricade more difficult and moving the military easier, and replaced cobblestones with macadam – a surface of crushed stone. As Flaubert observed in his Dictionary of Accepted Ideas: ‘Macadam: has cancelled revolutions. No more means to make barricades. Nevertheless rather inconvenient.’   Lead image: Barricades, as we know them today, are thought to have originated in early modern France. A colour engraving attributed to Achille‑Louis Martinet depicts the defence of a barricade during the 1830 July Revolution. Credit: Paris Musées / Musée Carnavalet – Histoire de Paris. Above: the socialist political thinker and activist Louis Auguste Blanqui – who was imprisoned by every regime that ruled France between 1815 and 1880 – drew instructions for how to build an effective barricade Under Napoleon III, Baron Haussmann widened Paris’s streets in his 1853–70 renovation of the city, making barricading more difficult Credit: Old Books Images / Alamy ‘On one hand, [the authorities] wanted to favour the circulation of ideas,’ reactionary intellectual Louis Veuillot observed apropos the ambiguous liberalism of the latter period of Napoleon III’s Second Empire. ‘On the other, to ensure the circulation of regiments.’ But ‘anti‑insurgency hardware’, as Justinien Tribillon has called it, also served to chase the working class out of the city centre: Haussmann’s projects amounted to a gigantic form of real-estate speculation, and the 1871 Paris Commune that followed constituted not just a short‑lived anarchist experiment featuring enormous barricades; it also signalled the return of the workers to the centre and, arguably, revenge for their dispossession.    By the mid‑19th century, observers questioned whether barricades still had practical meaning. Gottfried Semper’s barricade, constructed for the 1849 Dresden uprising, had proved unconquerable, but Friedrich Engels, one‑time ‘inspector of barricades’ in the Elberfeld insurrection of the same year, already suggested that the barricades’ primary meaning was now moral rather than military – a point to be echoed by Leon Trotsky in the subsequent century. Barricades symbolised bravery and the will to hold out among insurrectionists, and, not least, determination rather to destroy one’s possessions – and one’s neighbourhood – than put up with further oppression.   Not only self‑declared revolutionaries viewed things this way: the reformist Social Democrat leader Eduard Bernstein observed that ‘the barricade fight as a political weapon of the people has been completely eliminated due to changes in weapon technology and cities’ structures’. Bernstein was also picking up on the fact that, in the era of industrialisation, contention happened at least as much on the factory floor as on the streets. The strike, not the food riot or the defence of workers’ quartiers, became the paradigmatic form of conflict. Joshua Clover has pointed out in his 2016 book Riot. Strike. Riot: The New Era of Uprisings, that the price of labour, rather than the price of goods, caused people to confront the powerful. Blocking production grew more important than blocking the street. ‘The only weapons we have are our bodies, and we need to tuck them in places so wheels don’t turn’ Today, it is again blocking – not just people streaming along the streets in large marches – that is prominently associated with protests. Disrupting circulation is not only an important gesture in the face of climate emergency; blocking transport is a powerful form of protest in an economic system focused on logistics and just‑in‑time distribution. Members of Insulate Britain and Germany’s Last Generation super‑glue themselves to streets to stop car traffic to draw attention to the climate emergency; they have also attached themselves to airport runways. They form a human barricade of sorts, immobilising traffic by making themselves immovable.   Today’s protesters have made themselves consciously vulnerable. They in fact follow the advice of US civil rights’ Bayard Rustin who explained: ‘The only weapons we have are our bodies, and we need to tuck them in places so wheels don’t turn.’ Making oneself vulnerable might increase the chances of a majority of citizens seeing the importance of the cause which those engaged in civil disobedience are pursuing. Demonstrations – even large, unpredictable ones – are no longer sufficient. They draw too little attention and do not compel a reaction. Naomi Klein proposed the term ‘blockadia’ as ‘a roving transnational conflict zone’ in which people block extraction – be it open‑pit mines, fracking sites or tar sands pipelines – with their bodies. More often than not, these blockades are organised by local people opposing the fossil fuel industry, not environmental activists per se. Blockadia came to denote resistance to the Keystone XL pipeline as well as Canada’s First Nations‑led movement Idle No More. In cities, blocking can be accomplished with highly mobile structures. Like the barricade of the 19th century, they can be quickly assembled, yet are difficult to move; unlike old‑style barricades, they can also be quickly disassembled, removed and hidden (by those who have the engineering and architectural know‑how). Think of super tripods, intricate ‘protest beacons’ based on tensegrity principles, as well as inflatable cobblestones, pioneered by the artist‑activists of Tools for Action (and as analysed in Nick Newman’s recent volume Protest Architecture).   As recently as 1991, newly independent Latvia defended itself against Soviet tanks with the popular construction of barricades, in a series of confrontations that became known as the Barikādes Credit: Associated Press / Alamy Inversely, roadblocks can be used by police authorities to stop demonstrations and gatherings from taking place – protesters are seen removing such infrastructure in Dhaka during a general strike in 1999 Credit: REUTERS / Rafiqur Rahman / Bridgeman These inflatable objects are highly flexible, but can also be protective against police batons. They pose an awkward challenge to the authorities, who often end up looking ridiculous when dealing with them, and, as one of the inventors pointed out, they are guaranteed to create a media spectacle. This was also true of the 19th‑century barricade: people posed for pictures in front of them. As Wolfgang Scheppe, a curator of Architecture of the Barricade (currently on display at the Arsenale Institute for Politics of Representation in Venice), explains, these images helped the police to find Communards and mete out punishments after the end of the anarchist experiment. Much simpler structures can also be highly effective. In 2019, protesters in Hong Kong filled streets with little archways made from just three ordinary bricks: two standing upright, one resting on top. When touched, the falling top one would buttress the other two, and effectively block traffic. In line with their imperative of ‘be water’, protesters would retreat when the police appeared, but the ‘mini‑Stonehenges’ would remain and slow down the authorities. Today, elaborate architectures of protest, such as Extinction Rebellion’s ‘tensegrity towers’, are used to blockade roads and distribution networks – in this instance, Rupert Murdoch’s News UK printworks in Broxbourne, for the media group’s failure to report the climate emergency accurately Credit: Extinction Rebellion In June 2025, protests erupted in Los Angeles against the Trump administration’s deportation policies. Demonstrators barricaded downtown streets using various objects, including the pink public furniture designed by design firm Rios for Gloria Molina Grand Park. LAPD are seen advancing through tear gas Credit: Gina Ferazzi / Los Angeles Times via Getty Images Roads which radicals might want to target are not just ones in major metropoles and fancy post‑industrial downtowns. Rather, they might block the arteries leading to ‘fulfilment centres’ and harbours with container shipping. The model is not only Occupy Wall Street, which had initially called for the erection of ‘peaceful barricades’, but also the Occupy that led to the Oakland port shutdown in 2011. In short, such roadblocks disrupt what Phil Neel has called a ‘hinterland’ that is often invisible, yet crucial for contemporary capitalism. More recently, Extinction Rebellion targeted Amazon distribution centres in three European countries in November 2021; in the UK, they aimed to disrupt half of all deliveries on a Black Friday.   Will such blockades just anger consumers who, after all, are not present but are impatiently waiting for packages at home? One of the hopes associated with the traditional barricade was always that they might create spaces where protesters, police and previously indifferent citizens get talking; French theorists even expected them to become ‘a machine to produce the people’. That could be why military technology has evolved so that the authorities do not have to get close to the barricade: tear gas was first deployed against those on barricades before it was used in the First World War; so‑called riot control vehicles can ever more easily crush barricades. The challenge, then, for anyone who wishes to block is also how to get in other people’s faces – in order to have a chance to convince them of their cause.        2025-06-11 Kristina Rapacki Share

Your home address might be easier to find online than you think. A quick search of your name could turn up past and current locations, all thanks to people finder sites. These data broker sites quietly collect and publish personal details without your consent, making your privacy vulnerable with just a few clicks.Sign up for my FREE CyberGuy ReportGet my best tech tips, urgent security alerts, and exclusive deals delivered straight to your inbox. Plus, you’ll get instant access to my Ultimate Scam Survival Guide — free when you join. A woman searching for herself online. (Kurt "CyberGuy" Knutsson)How your address gets exposed online and who’s using itIf you’ve ever searched for your name and found personal details, like your address, on unfamiliar websites, you’re not alone. People finder platforms collect this information from public records and third-party data brokers, then publish and share it widely. They often link your address to other details such as phone numbers, email addresses and even relatives.11 EASY WAYS TO PROTECT YOUR ONLINE PRIVACY IN 2025While this data may already be public in various places, these sites make it far easier to access and monetize it at scale. In one recent breach, more than 183 million login credentials were exposed through an unsecured database. Many of these records were linked to physical addresses, raising concerns about how multiple sources of personal data can be combined and exploited.Although people finder sites claim to help reconnect friends or locate lost contacts, they also make sensitive personal information available to anyone willing to pay. This includes scammers, spammers and identity thieves who use it for fraud, harassment, and targeted scams. A woman searching for herself online. (Kurt "CyberGuy" Knutsson)How do people search sites get your home address?First, let’s define two sources of information; public and private databases that people search sites use to get your detailed profile, including your home address. They run an automated search on these databases with key information about you and add your home address from the search results. 1. Public sourcesYour home address can appear in:Property deeds: When you buy or sell a home, your name and address become part of the public record.Voter registration: You need to list your address when voting.Court documents: Addresses appear in legal filings or lawsuits.Marriage and divorce records: These often include current or past addresses.Business licenses and professional registrations: If you own a business or hold a license, your address can be listed.WHAT IS ARTIFICIAL INTELLIGENCE (AI)?These records are legal to access, and people finder sites collect and repackage them into detailed personal profiles.2. Private sourcesOther sites buy your data from companies you’ve interacted with:Online purchases: When you buy something online, your address is recorded and can be sold to marketing companies.Subscriptions and memberships: Magazines, clubs and loyalty programs often share your information.Social media platforms: Your location or address details can be gathered indirectly from posts, photos or shared information.Mobile apps and websites: Some apps track your location.People finder sites buy this data from other data brokers and combine it with public records to build complete profiles that include address information. A woman searching for herself online. (Kurt "CyberGuy" Knutsson)What are the risks of having your address on people finder sites?The Federal Trade Commission (FTC) advises people to request the removal of their private data, including home addresses, from people search sites due to the associated risks of stalking, scamming and other crimes.People search sites are a goldmine for cybercriminals looking to target and profile potential victims as well as plan comprehensive cyberattacks. Losses due to targeted phishing attacks increased by 33% in 2024, according to the FBI. So, having your home address publicly accessible can lead to several risks:Stalking and harassment: Criminals can easily find your home address and threaten you.Identity theft: Scammers can use your address and other personal information to impersonate you or fraudulently open accounts.Unwanted contact: Marketers and scammers can use your address to send junk mail or phishing or brushing scams.Increased financial risks: Insurance companies or lenders can use publicly available address information to unfairly decide your rates or eligibility.Burglary and home invasion: Criminals can use your location to target your home when you’re away or vulnerable.How to protect your home addressThe good news is that you can take steps to reduce the risks and keep your address private. However, keep in mind that data brokers and people search sites can re-list your information after some time, so you might need to request data removal periodically.I recommend a few ways to delete your private information, including your home address, from such websites.1. Use personal data removal services: Data brokers can sell your home address and other personal data to multiple businesses and individuals, so the key is to act fast. If you’re looking for an easier way to protect your privacy, a data removal service can do the heavy lifting for you, automatically requesting data removal from brokers and tracking compliance.While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap — and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you. Check out my top picks for data removal services here. Get a free scan to find out if your personal information is already out on the web2. Opt out manually : Use a free scanner provided by a data removal service to check which people search sites that list your address. Then, visit each of these websites and look for an opt-out procedure or form: keywords like "opt out," "delete my information," etc., point the way.Follow each site’s opt-out process carefully, and confirm they’ve removed all your personal info, otherwise, it may get relisted.3. Monitor your digital footprint: I recommend regularly searching online for your name to see if your location is publicly available. If only your social media profile pops up, there’s no need to worry. However, people finder sites tend to relist your private information, including your home address, after some time.4. Limit sharing your address online: Be careful about sharing your home address on social media, online forms and apps. Review privacy settings regularly, and only provide your address when absolutely necessary. Also, adjust your phone settings so that apps don’t track your location.Kurt’s key takeawaysYour home address is more vulnerable than you think. People finder sites aggregate data from public records and private sources to display your address online, often without your knowledge or consent. This can lead to serious privacy and safety risks. Taking proactive steps to protect your home address is essential. Do it manually or use a data removal tool for an easier process. By understanding how your location is collected and taking measures to remove your address from online sites, you can reclaim control over your personal data.CLICK HERE TO GET THE FOX NEWS APPHow do you feel about companies making your home address so easy to find?

In 2024, Egypt completed its 1,155km stretch of the Cairo–Cape Town Highway, a 10,228km‑long road connecting 10 African countries – Egypt, Sudan, South Sudan, Ethiopia, Kenya, Tanzania, Zambia, Zimbabwe, Botswana and South Africa.   The imaginary of ‘Cape to Cairo’ is not new. In 1874, editor of the Daily Telegraph Edwin Arnold proposed a plan to connect the African continent by rail, a project that came to be known as the Cape to Cairo Railway project. Cecil Rhodes expressed his support for the project, seeing it as a means to connect the various ‘possessions’ of the British Empire across Africa, facilitating the movement of troops and natural resources. This railway project was never completed, and in 1970 was overlaid by a very different attempt at connecting the Cape to Cairo, as part of the Trans‑African Highway network. This 56,683km‑long system of highways – some dating from the colonial era, some built as part of the 1970s project, and some only recently built – aimed to create lines of connection across the African continent, from north to south as well as east to west.  Here, postcolonial state power invested in ‘moving the continent’s people and economies from past to future’, as architectural historians Kenny Cupers and Prita Meier write in their 2020 essay ‘Infrastructure between Statehood and Selfhood: The Trans‑African Highway’. The highways were to be built with the support of Kenya’s president Jomo Kenyatta, Ghana’s president Kwame Nkrumah and Ghana’s director of social welfare Robert Gardiner, as well as the United Nations Economic Commission for Africa (UNECA). This project was part of a particular historical moment during which anticolonial ideas animated most of the African continent; alongside trade, this iteration of Cape to Cairo centred social and cultural connection between African peoples. But though largely socialist in ambition, the project nevertheless engaged modernist developmentalist logics that cemented capitalism.  Lead image: Over a century in the making, the final stretches of the Cairo–Cape Town Highway are being finished. Egypt completed the section within its borders last year and a section over the dry Merille River in Kenya was constructed in 2019. Credit: Allan Muturi / SOPA / ZUMA / Alamy. Above: The route from Cairo to Cape Town, outlined in red, belongs to the Trans‑African Highway network, which comprises nine routes, here in black The project failed to fully materialise at the time, but efforts to complete the Trans‑African Highway network have been revived in the last 20 years; large parts are now complete though some links remain unbuilt and many roads are unpaved or hazardous. The most recent attempts to realise this project coincide with a new continental free trade agreement, the agreement on African Continental Free Trade Area (AfCFTA), established in 2019, to increase trade within the continent. The contemporary manifestation of the Cairo–Cape Town Highway – also known as Trans‑African Highway (TAH) 4 – is marked by deepening neoliberal politics. Represented as an opportunity to boost trade and exports, connecting Egypt to African markets that the Egyptian government view as ‘untapped’, the project invokes notions of trade steeped in extraction, reflecting the neoliberal logic underpinning contemporary Egyptian governance; today, the country’s political project, led by Abdel Fattah El Sisi, is oriented towards Egyptian dominance and extraction in relation to the rest of the continent.  Through an allusion to markets ripe for extraction, this language brings to the fore historical forms of domination that have shaped the connections between Egypt and the rest of the continent; previous iterations of connection across the continent often reproduced forms of domination stretching from the north of the African continent to the south, including the Trans‑Saharan slave trade routes across Africa that ended in various North African and Middle Eastern territories. These networks, beginning in the 8th century and lasting until the 20th, produced racialised hierarchies across the continent, shaping North Africa into a comparably privileged space proximate to ‘Arabness’. This was a racialised division based on a civilisational narrative that saw Arabs as superior, but more importantly a political economic division resulting from the slave trade routes that produced huge profits for North Africa and the Middle East. In the contemporary moment, these racialised hierarchies are bound up in political economic dependency on the Arab Gulf states, who are themselves dependent on resource extraction, land grabbing and privatisation across the entire African continent.  ‘The Cairo–Cape Town Highway connects Egypt to African markets viewed as “untapped”, invoking notions steeped in extraction’ However, this imaginary conjured by the Cairo–Cape Town Highway is countered by a network of streets scattered across Africa that traces the web of Egyptian Pan‑African solidarity across the continent. In Lusaka in Zambia, you might find yourself on Nasser Road, as you might in Mwanza in Tanzania or Luanda in Angola. In Mombasa in Kenya, you might be driving down Abdel Nasser Road; in Kampala in Uganda, you might find yourself at Nasser Road University; and in Tunis in Tunisia, you might end up on Gamal Abdel Nasser Street. These street names are a reference to Gamal Abdel Nasser, Egypt’s first postcolonial leader and president between 1956 and 1970.  Read against the contemporary Cairo–Cape Town Highway, these place names signal a different form of connection that brings to life Egyptian Pan‑Africanism, when solidarity was the hegemonic force connecting the continent, coming up against the notion of a natural or timeless ‘great divide’ within Africa. From the memoirs of Egyptian officials who were posted around Africa as conduits of solidarity, to the broadcasts of Radio Cairo that were heard across the continent, to the various conferences attended by anticolonial movements and postcolonial states, Egypt’s orientation towards Pan‑Africanism, beginning in the early 20th century and lasting until the 1970s, was both material and ideological. Figures and movements forged webs of solidarity with their African comrades, imagining an Africa that was united through shared commitments to ending colonialism and capitalist extraction.  The route between Cape Town in South Africa and Cairo in Egypt has long occupied the colonial imaginary. In 1930, Margaret Belcher and Ellen Budgell made the journey, sponsored by car brand Morris and oil company Shell Credit: Fox Photos / Getty The pair made use of the road built by British colonisers in the 19th century, and which forms the basis for the current Cairo–Cape Town Highway. The road was preceded by the 1874 Cape to Cairo Railway project, which connected the colonies of the British Empire Credit: Library of Congress, Geography and Map Division This network of eponymous streets represents attempts to inscribe anticolonial power into the materiality of the city. Street‑naming practices are one way in which the past comes into the present, ‘weaving history into the geographic fabric of everyday life’, as geographer Derek Alderman wrote in his 2002 essay ‘Street Names as Memorial Arenas’. In this vein, the renaming of streets during decolonisation marked a practice of contesting the production of colonial space. In the newly postcolonial city, renaming was a way of ‘claiming the city back’, Alderman continues. While these changes may appear discursive, it is their embedding in material spaces, through signs and maps, that make the names come to life; place names become a part of the everyday through sharing addresses or giving directions. This quality makes them powerful; consciously or unconsciously, they form part of how the spaces of the city are navigated.  These are traces that were once part of a dominant historical narrative; yet when they are encountered in the present, during a different historical moment, they no longer act as expressions of power but instead conjure up a moment that has long passed. A street in Lusaka named after an Egyptian general made more sense 60 years ago than it does today, yet contextualising it recovers a marginalised history of Egyptian Pan‑Africanism.  Markers such as street names or monuments are simultaneously markers of anticolonial struggle as well as expressions of state power – part of an attempt, by political projects such as Nasser’s, to exert their own dominance over cities, towns and villages. That such traces are expressions of both anticolonial hopes and postcolonial state power produces a sense of tension within them. For instance, Nasser’s postcolonial project in Egypt was a contradictory one; it gave life to anticolonial hopes – for instance by breaking away from European capitalism and embracing anticolonial geopolitics – while crushing many parts of the left through repression, censorship and imprisonment. Traces of Nasser found today inscribe both anticolonial promises – those that came to life and those that did not – while reproducing postcolonial power that in most instances ended in dictatorship.  Recent efforts to complete the route build on those of the post‑independence era – work on a section north of Nairobi started in 1968 Credit: Associated Press / Alamy The Trans‑African Highway network was conceived in 1970 in the spirit of Pan‑Africanism At that time, the routes did not extend into South Africa, which was in the grip of apartheid. The Trans‑African Highway initiative was motivated by a desire to improve trade and centre cultural links across the continent – an ambition that was even celebrated on postage stamps There have been long‑standing debates about the erasure of the radical anticolonial spirit from the more conservative postcolonial states that emerged; the promises and hopes of anticolonialism, not least among them socialism and a world free of white supremacy, remain largely unrealised. Instead, by the 1970s neoliberalism emerged as a new hegemonic project. The contemporary instantiation of Cape to Cairo highlights just how pervasive neoliberal logics continue to be, despite multiple global financial crises and the 2011 Egyptian revolution demanding ‘bread, freedom, social justice’.  But the network of streets named after anticolonial figures and events across the world is testament to the immense power and promise of anticolonial revolution. Most of the 20th century was characterised by anticolonial struggle, decolonisation and postcolonial nation‑building, as nations across the global south gained independence from European empire and founded their own political projects. Anticolonial traces, present in street and place names, point to the possibility of solidarity as a means of reorienting colonial geographies. They are a reminder that there have been other imaginings of Cape to Cairo, and that things can be – and have been – otherwise. 2025-06-13 Kristina Rapacki Share

Guided by visual effects supervisor John Knoll, ILM embraced continually evolving methodologies to craft breathtaking visual effects for the iconic space battles in First Contact and Rogue One. By Jay Stobie Visual effects supervisor John Knoll (right) confers with modelmakers Kim Smith and John Goodson with the miniature of the U.S.S. Enterprise-E during production of Star Trek: First Contact (Credit: ILM). Bolstered by visual effects from Industrial Light & Magic, Star Trek: First Contact (1996) and Rogue One: A Star Wars Story (2016) propelled their respective franchises to new heights. While Star Trek Generations (1994) welcomed Captain Jean-Luc Picard’s (Patrick Stewart) crew to the big screen, First Contact stood as the first Star Trek feature that did not focus on its original captain, the legendary James T. Kirk (William Shatner). Similarly, though Rogue One immediately preceded the events of Star Wars: A New Hope (1977), it was set apart from the episodic Star Wars films and launched an era of storytelling outside of the main Skywalker saga that has gone on to include Solo: A Star Wars Story (2018), The Mandalorian (2019-23), Andor (2022-25), Ahsoka (2023), The Acolyte (2024), and more. The two films also shared a key ILM contributor, John Knoll, who served as visual effects supervisor on both projects, as well as an executive producer on Rogue One. Currently, ILM’s executive creative director and senior visual effects supervisor, Knoll – who also conceived the initial framework for Rogue One’s story – guided ILM as it brought its talents to bear on these sci-fi and fantasy epics. The work involved crafting two spectacular starship-packed space clashes – First Contact’s Battle of Sector 001 and Rogue One’s Battle of Scarif. Although these iconic installments were released roughly two decades apart, they represent a captivating case study of how ILM’s approach to visual effects has evolved over time. With this in mind, let’s examine the films’ unforgettable space battles through the lens of fascinating in-universe parallels and the ILM-produced fleets that face off near Earth and Scarif. A final frame from the Battle of Scarif in Rogue One: A Star Wars Story (Credit: ILM & Lucasfilm). A Context for Conflict In First Contact, the United Federation of Planets – a 200-year-old interstellar government consisting of more than 150 member worlds – braces itself for an invasion by the Borg – an overwhelmingly powerful collective composed of cybernetic beings who devastate entire planets by assimilating their biological populations and technological innovations. The Borg only send a single vessel, a massive cube containing thousands of hive-minded drones and their queen, pushing the Federation’s Starfleet defenders to Earth’s doorstep. Conversely, in Rogue One, the Rebel Alliance – a fledgling coalition of freedom fighters – seeks to undermine and overthrow the stalwart Galactic Empire – a totalitarian regime preparing to tighten its grip on the galaxy by revealing a horrifying superweapon. A rebel team infiltrates a top-secret vault on Scarif in a bid to steal plans to that battle station, the dreaded Death Star, with hopes of exploiting a vulnerability in its design. On the surface, the situations could not seem to be more disparate, particularly in terms of the Federation’s well-established prestige and the Rebel Alliance’s haphazardly organized factions. Yet, upon closer inspection, the spaceborne conflicts at Earth and Scarif are linked by a vital commonality. The threat posed by the Borg is well-known to the Federation, but the sudden intrusion upon their space takes its defenses by surprise. Starfleet assembles any vessel within range – including antiquated Oberth-class science ships – to intercept the Borg cube in the Typhon Sector, only to be forced back to Earth on the edge of defeat. The unsanctioned mission to Scarif with Jyn Erso (Felicity Jones) and Cassian Andor (Diego Luna) and the sudden need to take down the planet’s shield gate propels the Rebel Alliance fleet into rushing to their rescue with everything from their flagship Profundity to GR-75 medium transports. Whether Federation or Rebel Alliance, these fleets gather in last-ditch efforts to oppose enemies who would embrace their eradication – the Battles of Sector 001 and Scarif are fights for survival. From Physical to Digital By the time Jonathan Frakes was selected to direct First Contact, Star Trek’s reliance on constructing traditional physical models (many of which were built by ILM) for its features was gradually giving way to innovative computer graphics (CG) models, resulting in the film’s use of both techniques. “If one of the ships was to be seen full-screen and at length,” associate visual effects supervisor George Murphy told Cinefex’s Kevin H. Martin, “we knew it would be done as a stage model. Ships that would be doing a lot of elaborate maneuvers in space battle scenes would be created digitally.” In fact, physical and CG versions of the U.S.S. Enterprise-E appear in the film, with the latter being harnessed in shots involving the vessel’s entry into a temporal vortex at the conclusion of the Battle of Sector 001. Despite the technological leaps that ILM pioneered in the decades between First Contact and Rogue One, they considered filming physical miniatures for certain ship-related shots in the latter film. ILM considered filming physical miniatures for certain ship-related shots in Rogue One. The feature’s fleets were ultimately created digitally to allow for changes throughout post-production. “If it’s a photographed miniature element, it’s not possible to go back and make adjustments. So it’s the additional flexibility that comes with the computer graphics models that’s very attractive to many people,” John Knoll relayed to writer Jon Witmer at American Cinematographer’s TheASC.com. However, Knoll aimed to develop computer graphics that retained the same high-quality details as their physical counterparts, leading ILM to employ a modern approach to a time-honored modelmaking tactic. “I also wanted to emulate the kit-bashing aesthetic that had been part of Star Wars from the very beginning, where a lot of mechanical detail had been added onto the ships by using little pieces from plastic model kits,” explained Knoll in his chat with TheASC.com. For Rogue One, ILM replicated the process by obtaining such kits, scanning their parts, building a computer graphics library, and applying the CG parts to digitally modeled ships. “I’m very happy to say it was super-successful,” concluded Knoll. “I think a lot of our digital models look like they are motion-control models.” John Knoll (second from left) confers with Kim Smith and John Goodson with the miniature of the U.S.S. Enterprise-E during production of Star Trek: First Contact (Credit: ILM). Legendary Lineages In First Contact, Captain Picard commanded a brand-new vessel, the Sovereign-class U.S.S. Enterprise-E, continuing the celebrated starship’s legacy in terms of its famous name and design aesthetic. Designed by John Eaves and developed into blueprints by Rick Sternbach, the Enterprise-E was built into a 10-foot physical model by ILM model project supervisor John Goodson and his shop’s talented team. ILM infused the ship with extraordinary detail, including viewports equipped with backlit set images from the craft’s predecessor, the U.S.S. Enterprise-D. For the vessel’s larger windows, namely those associated with the observation lounge and arboretum, ILM took a painstakingly practical approach to match the interiors shown with the real-world set pieces. “We filled that area of the model with tiny, micro-scale furniture,” Goodson informed Cinefex, “including tables and chairs.” Rogue One’s rebel team initially traversed the galaxy in a U-wing transport/gunship, which, much like the Enterprise-E, was a unique vessel that nonetheless channeled a certain degree of inspiration from a classic design. Lucasfilm’s Doug Chiang, a co-production designer for Rogue One, referred to the U-wing as the film’s “Huey helicopter version of an X-wing” in the Designing Rogue One bonus featurette on Disney+ before revealing that, “Towards the end of the design cycle, we actually decided that maybe we should put in more X-wing features. And so we took the X-wing engines and literally mounted them onto the configuration that we had going.” Modeled by ILM digital artist Colie Wertz, the U-wing’s final computer graphics design subtly incorporated these X-wing influences to give the transport a distinctive feel without making the craft seem out of place within the rebel fleet. While ILM’s work on the Enterprise-E’s viewports offered a compelling view toward the ship’s interior, a breakthrough LED setup for Rogue One permitted ILM to obtain realistic lighting on actors as they looked out from their ships and into the space around them. “All of our major spaceship cockpit scenes were done that way, with the gimbal in this giant horseshoe of LED panels we got from [equipment vendor] VER, and we prepared graphics that went on the screens,” John Knoll shared with American Cinematographer’s Benjamin B and Jon D. Witmer. Furthermore, in Disney+’s Rogue One: Digital Storytelling bonus featurette, visual effects producer Janet Lewin noted, “For the actors, I think, in the space battle cockpits, for them to be able to see what was happening in the battle brought a higher level of accuracy to their performance.” The U.S.S. Enterprise-E in Star Trek: First Contact (Credit: Paramount). Familiar Foes To transport First Contact’s Borg invaders, John Goodson’s team at ILM resurrected the Borg cube design previously seen in Star Trek: The Next Generation (1987) and Star Trek: Deep Space Nine (1993), creating a nearly three-foot physical model to replace the one from the series. Art consultant and ILM veteran Bill George proposed that the cube’s seemingly straightforward layout be augmented with a complex network of photo-etched brass, a suggestion which produced a jagged surface and offered a visual that was both intricate and menacing. ILM also developed a two-foot motion-control model for a Borg sphere, a brand-new auxiliary vessel that emerged from the cube. “We vacuformed about 15 different patterns that conformed to this spherical curve and covered those with a lot of molded and cast pieces. Then we added tons of acid-etched brass over it, just like we had on the cube,” Goodson outlined to Cinefex’s Kevin H. Martin. As for Rogue One’s villainous fleet, reproducing the original trilogy’s Death Star and Imperial Star Destroyers centered upon translating physical models into digital assets. Although ILM no longer possessed A New Hope’s three-foot Death Star shooting model, John Knoll recreated the station’s surface paneling by gathering archival images, and as he spelled out to writer Joe Fordham in Cinefex, “I pieced all the images together. I unwrapped them into texture space and projected them onto a sphere with a trench. By doing that with enough pictures, I got pretty complete coverage of the original model, and that became a template upon which to redraw very high-resolution texture maps. Every panel, every vertical striped line, I matched from a photograph. It was as accurate as it was possible to be as a reproduction of the original model.” Knoll’s investigative eye continued to pay dividends when analyzing the three-foot and eight-foot Star Destroyer motion-control models, which had been built for A New Hope and Star Wars: The Empire Strikes Back (1980), respectively. “Our general mantra was, ‘Match your memory of it more than the reality,’ because sometimes you go look at the actual prop in the archive building or you look back at the actual shot from the movie, and you go, ‘Oh, I remember it being a little better than that,’” Knoll conveyed to TheASC.com. This philosophy motivated ILM to combine elements from those two physical models into a single digital design. “Generally, we copied the three-footer for details like the superstructure on the top of the bridge, but then we copied the internal lighting plan from the eight-footer,” Knoll explained. “And then the upper surface of the three-footer was relatively undetailed because there were no shots that saw it closely, so we took a lot of the high-detail upper surface from the eight-footer. So it’s this amalgam of the two models, but the goal was to try to make it look like you remember it from A New Hope.” A final frame from Rogue One: A Star Wars Story (Credit: ILM & Lucasfilm). Forming Up the Fleets In addition to the U.S.S. Enterprise-E, the Battle of Sector 001 debuted numerous vessels representing four new Starfleet ship classes – the Akira, Steamrunner, Saber, and Norway – all designed by ILM visual effects art director Alex Jaeger. “Since we figured a lot of the background action in the space battle would be done with computer graphics ships that needed to be built from scratch anyway, I realized that there was no reason not to do some new designs,” John Knoll told American Cinematographer writer Ron Magid. Used in previous Star Trek projects, older physical models for the Oberth and Nebula classes were mixed into the fleet for good measure, though the vast majority of the armada originated as computer graphics. Over at Scarif, ILM portrayed the Rebel Alliance forces with computer graphics models of fresh designs (the MC75 cruiser Profundity and U-wings), live-action versions of Star Wars Rebels’ VCX-100 light freighter Ghost and Hammerhead corvettes, and Star Wars staples (Nebulon-B frigates, X-wings, Y-wings, and more). These ships face off against two Imperial Star Destroyers and squadrons of TIE fighters, and – upon their late arrival to the battle – Darth Vader’s Star Destroyer and the Death Star. The Tantive IV, a CR90 corvette more popularly referred to as a blockade runner, made its own special cameo at the tail end of the fight. As Princess Leia Organa’s (Carrie Fisher and Ingvild Deila) personal ship, the Tantive IV received the Death Star plans and fled the scene, destined to be captured by Vader’s Star Destroyer at the beginning of A New Hope. And, while we’re on the subject of intricate starship maneuvers and space-based choreography… Although the First Contact team could plan visual effects shots with animated storyboards, ILM supplied Gareth Edwards with a next-level virtual viewfinder that allowed the director to select his shots by immersing himself among Rogue One’s ships in real time. “What we wanted to do is give Gareth the opportunity to shoot his space battles and other all-digital scenes the same way he shoots his live-action. Then he could go in with this sort of virtual viewfinder and view the space battle going on, and figure out what the best angle was to shoot those ships from,” senior animation supervisor Hal Hickel described in the Rogue One: Digital Storytelling featurette. Hickel divulged that the sequence involving the dish array docking with the Death Star was an example of the “spontaneous discovery of great angles,” as the scene was never storyboarded or previsualized. Visual effects supervisor John Knoll with director Gareth Edwards during production of Rogue One: A Star Wars Story (Credit: ILM & Lucasfilm). Tough Little Ships The Federation and Rebel Alliance each deployed “tough little ships” (an endearing description Commander William T. Riker [Jonathan Frakes] bestowed upon the U.S.S. Defiant in First Contact) in their respective conflicts, namely the U.S.S. Defiant from Deep Space Nine and the Tantive IV from A New Hope. VisionArt had already built a CG Defiant for the Deep Space Nine series, but ILM upgraded the model with images gathered from the ship’s three-foot physical model. A similar tactic was taken to bring the Tantive IV into the digital realm for Rogue One. “This was the Blockade Runner. This was the most accurate 1:1 reproduction we could possibly have made,” model supervisor Russell Paul declared to Cinefex’s Joe Fordham. “We did an extensive photo reference shoot and photogrammetry re-creation of the miniature. From there, we built it out as accurately as possible.” Speaking of sturdy ships, if you look very closely, you can spot a model of the Millennium Falcon flashing across the background as the U.S.S. Defiant makes an attack run on the Borg cube at the Battle of Sector 001! Exploration and Hope The in-universe ramifications that materialize from the Battles of Sector 001 and Scarif are monumental. The destruction of the Borg cube compels the Borg Queen to travel back in time in an attempt to vanquish Earth before the Federation can even be formed, but Captain Picard and the Enterprise-E foil the plot and end up helping their 21st century ancestors make “first contact” with another species, the logic-revering Vulcans. The post-Scarif benefits take longer to play out for the Rebel Alliance, but the theft of the Death Star plans eventually leads to the superweapon’s destruction. The Galactic Civil War is far from over, but Scarif is a significant step in the Alliance’s effort to overthrow the Empire. The visual effects ILM provided for First Contact and Rogue One contributed significantly to the critical and commercial acclaim both pictures enjoyed, a victory reflecting the relentless dedication, tireless work ethic, and innovative spirit embodied by visual effects supervisor John Knoll and ILM’s entire staff. While being interviewed for The Making of Star Trek: First Contact, actor Patrick Stewart praised ILM’s invaluable influence, emphasizing, “ILM was with us, on this movie, almost every day on set. There is so much that they are involved in.” And, regardless of your personal preferences – phasers or lasers, photon torpedoes or proton torpedoes, warp speed or hyperspace – perhaps Industrial Light & Magic’s ability to infuse excitement into both franchises demonstrates that Star Trek and Star Wars encompass themes that are not competitive, but compatible.

Solar air heating is among the most cost-effective applications of solar thermal energy. These systems are used for space heating and preheating fresh air for ventilation, typically using glazed or unglazed perforated solar collectors. The collectors draw in outside air, heat it using solar energy, and then distribute it through ductwork to meet building heating and fresh air needs. In 2024, Canada led again the world for the at least seventh year in a row in solar air heating adoption. The four key suppliers – Trigo Energies, Conserval Engineering, Matrix Energy, and Aéronergie – reported a combined 26,203 m2 (282,046 ft2) of collector area sold last year. Several of these providers are optimistic about the growing demand. These findings come from the newly released Canadian Solar Thermal Market Survey 2024, commissioned by Natural Resources Canada. Canada is the global leader in solar air heating. The market is driven by a strong network of experienced system suppliers, optimized technologies, and a few small favorable funding programs – especially in the province of Quebec. Architects and developers are increasingly turning to these cost-effective, façade-integrated systems as a practical solution for reducing onsite natural gas consumption. Despite its cold climate, Canada benefits from strong solar potential with solar irradiance in many areas rivaling or even exceeding that of parts of Europe. This makes solar air heating not only viable, but especially valuable in buildings with high fresh air requirements including schools, hospitals, and offices. The projects highlighted in this article showcase the versatility and relevance of solar air heating across a range of building types, from new constructions to retrofits. Figure 1: Preheating air for industrial buildings: 2,750 m2 (29,600 ft2) of Calento SL solar air collectors cover all south-west and south-east facing facades of the FAB3R factory in Trois-Rivières, Quebec. The hourly unitary flow rate is set at 41 m3/m2 or 2.23 cfm/ft2 of collector area, at the lower range because only a limited number of intake fans was close enough to the solar façade to avoid long ventilation ductwork. Photo: Trigo Energies Quebec’s solar air heating boom: the Trigo Energies story Trigo Energies makes almost 90 per cent of its sales in Quebec. “We profit from great subsidies, as solar air systems are supported by several organizations in our province – the electricity utility Hydro Quebec, the gas utility Energir and the Ministry of Natural Resources,” explained Christian Vachon, Vice President Technologies and R&D at Trigo Energies. Trigo Energies currently has nine employees directly involved in planning, engineering and installing solar air heating systems and teams up with several partner contractors to install mostly retrofit projects. “A high degree of engineering is required to fit a solar heating system into an existing factory,” emphasized Vachon. “Knowledge about HVAC engineering is as important as experience with solar thermal and architecture.” One recent Trigo installation is at the FAB3R factory in Trois-Rivières. FAB3R specializes in manufacturing, repairing, and refurbishing large industrial equipment. Its air heating and ventilation system needed urgent renovation because of leakages and discomfort for the workers. “Due to many positive references he had from industries in the area, the owner of FAB3R contacted us,” explained Vachon. “The existence of subsidies helped the client to go for a retrofitting project including solar façade at once instead of fixing the problems one bit at a time.” Approximately 50 per cent of the investment costs for both the solar air heating and the renovation of the indoor ventilation system were covered by grants and subsidies. FAB3R profited from an Energir grant targeted at solar preheating, plus an investment subsidy from the Government of Quebec’s EcoPerformance Programme.   Blue or black, but always efficient: the advanced absorber coating In October 2024, the majority of the new 2,750 m² (29,600 ft2) solar façade at FAB3R began operation (see figure 1). According to Vachon, the system is expected to cover approximately 13 per cent of the factory’s annual heating demand, which is otherwise met by natural gas. Trigo Energies equipped the façade with its high-performance Calento SL collectors, featuring a notable innovation: a selective, low-emissivity coating that withstands outdoor conditions. Introduced by Trigo in 2019 and manufactured by Almeco Group from Italy, this advanced coating is engineered to maximize solar absorption while minimizing heat loss via infrared emission, enhancing the overall efficiency of the system. The high efficiency coating is now standard in Trigo’s air heating systems. According to the manufacturer, the improved collector design shows a 25 to 35 per cent increase in yield over the former generation of solar air collectors with black paint. Testing conducted at Queen’s University confirms this performance advantage. Researchers measured the performance of transpired solar air collectors both with and without a selective coating, mounted side-by-side on a south-facing vertical wall. The results showed that the collectors with the selective coating produced 1.3 to 1.5 times more energy than those without it. In 2024, the monitoring results were jointly published by Queen’s University and Canmat Energy in a paper titled Performance Comparison of a Transpired Air Solar Collector with Low-E Surface Coating. Selective coating, also used on other solar thermal technologies including glazed flat plate or vacuum tube collectors, has a distinctive blue color. Trigo customers can, however, choose between blue and black finishes. “By going from the normal blue selective coating to black selective coating, which Almeco is specially producing for Trigo, we lose about 1 per cent in solar efficiency,” explained Vachon.

Photo: Matrix Energy Matrix Energy: collaborating with architects and engineers in new builds The key target customer group of Matrix Energy are public buildings – mainly new construction. “Since the pandemic, schools are more conscious about fresh air, and solar preheating of the incoming fresh air has a positive impact over the entire school year,” noted Brian Wilkinson, President of Matrix Energy. Matrix Energy supplies systems across Canada, working with local partners to source and process the metal sheets used in their MatrixAir collectors. These metal sheets are perforated and then formed into architectural cladding profiles. The company exclusively offers unglazed, single-stage collectors, citing fire safety concerns associated with polymeric covers. “We have strong relationships with many architects and engineers who appreciate the simplicity and cost-effectiveness of transpired solar air heating systems,” said President Brian Wilkinson, describing the company’s sales approach. “Matrix handles system design and supplies the necessary materials, while installation is carried out by specialized cladding and HVAC contractors overseen by on-site architects and engineers,” Wilkinson added. Finding the right flow: the importance of unitary airflow rates One of the key design factors in solar air heating systems is the amount of air that passes through each square meter of the perforated metal absorber,  known as the unitary airflow rate. The principle is straightforward: higher airflow rates deliver more total heat to the building, while lower flow rates result in higher outlet air temperatures. Striking the right balance between air volume and temperature gain is essential for efficient system performance. For unglazed collectors mounted on building façades, typical hourly flow rates should range between 120 and 170 (m3/h/m2), or 6.6 to 9.4 cfm/ft2. However, Wilkinson suggests that an hourly airflow rate of around 130 m³/h/m² (7.2 cfm/ft2) offers the best cost-benefit balance for building owners. If the airflow is lower, the system will deliver higher air temperatures, but it would then need a much larger collector area to achieve the same air volume and optimum performance, he explained. It’s also crucial for the flow rate to overcome external wind pressure. As wind passes over the absorber, air flow through the collector’s perforations is reduced, resulting in heat losses to the environment. This effect becomes even more pronounced in taller buildings, where wind exposure is greater. To ensure the system performs well even in these conditions, higher hourly airflow rates typically between 150 and 170 m³/m² (8.3 to 9.4 cfm/ft2)  are necessary.

Photo: Conserval Engineering Solar air heating systems support LEED-certified building designs Solar air collectors are also well-suited for use in multi-unit residential buildings. A prime example is the Canary District in Toronto (see Figure 3), where single-stage SolarWall collectors from Conserval Engineering have been installed on several MURBs to clad the mechanical penthouses. “These penthouses are an ideal location for our air heating collectors, as they contain the make-up air units that supply corridor ventilation throughout the building,” explained Victoria Hollick, Vice President of Conserval Engineering. “The walls are typically finished with metal façades, which can be seamlessly replaced with a SolarWall system – maintaining the architectural language without disruption.” To date, nine solar air heating systems have been commissioned in the Canary District, covering a total collector area of over 1,000 m² (10,764 ft2). “Our customers have many motivations to integrate SolarWall technology into their new construction or retrofit projects, either carbon reduction, ESG, or green building certification targets,” explained Hollick. The use of solar air collectors in the Canary District was proposed by architects from the Danish firm Cobe. The black-colored SolarWall system preheats incoming air before it is distributed to the building’s corridors and common areas, reducing reliance on natural gas heating and supporting the pursuit of LEED Gold certification. Hollick estimates the amount of gas saved between 10 to 20 per cent of the total heating load for the corridor ventilation of the multi-unit residential buildings. Additional energy-saving strategies include a 50/50 window-to-wall ratio with high-performance glazing, green roofs, high-efficiency mechanical systems, LED lighting, and Energy Star-certified appliances. The ideal orientation for a SolarWall system is due south. However, the systems can be built at any orientation up to 90° east and west, explained Hollick. A SolarWall at 90° would have approximately 60 per cent of the energy production of the same area facing south.Canada’s expertise in solar air heating continues to set a global benchmark, driven by supporting R&D, by innovative technologies, strategic partnerships, and a growing portfolio of high-impact projects. With strong policy support and proven performance, solar air heating is poised to play a key role in the country’s energy-efficient building future.
