5 Terracotta Coolers That Look Like Sculptures and Work Without Power

Posted on by

Traditional cooling methods are gaining fresh attention as homeowners and designers search for environmentally responsible alternatives to energy-intensive air conditioning. Among these, clay coolers have emerged as a practical and elegant solution rooted in centuries-old craftsmanship. Their ability to cool naturally without relying on electricity aligns perfectly with the growing demand for sustainable living and climate-responsive design.

Today, architects are integrating these timeless cooling systems into modern homes. By combining natural materials, passive cooling principles, and thoughtful aesthetics, clay coolers are rediscovering solutions that have stood the test of time.

1. The Timeless Science Behind Clay Cooling

Clay coolers function through the principle of evaporative cooling, one of the oldest and most effective natural cooling techniques. The porous clay absorbs water, and as the moisture gradually evaporates, it draws heat from the surrounding air, lowering the temperature without consuming electricity. This process creates a gentle cooling effect that feels comfortable. Unlike conventional air conditioners that depend on compressors and refrigerants, clay coolers work in harmony with natural environmental conditions.

Their simple engineering offer an energy-efficient solution that remains highly relevant for contemporary architecture.

MALU is a thoughtfully designed personal cooling system that transforms the ancient principle of evaporative cooling into a contemporary home product. Created by Austrian designer Katja Posch, the compact cooler features a porous terracotta cylinder supported by a handcrafted wooden frame and topped with a circular wooden water tray. Measuring 700 millimetres tall and 280 millimetres wide, MALU is designed to function as both a cooling device and a sculptural furniture piece. Its minimalist form, warm earthy materials, and refined craftsmanship allow it to blend seamlessly into modern interiors while offering an environmentally conscious alternative to conventional cooling appliances.

Water poured into the wooden tray gradually filters through the 8-millimetre-thick terracotta body, where natural evaporation cools the surrounding air before it is released through slim horizontal vents. An optional low-energy fan housed within the wooden base enhances airflow, while the cooler remains effective even in passive mode. Constructed from repairable, recyclable terracotta and wood, MALU is designed for durability and long-term use.

2. A Sustainable Alternative to Energy-Intensive Cooling

As global temperatures continue to rise, reducing energy consumption has become a priority for both homeowners and the construction industry. Clay coolers provide an environmentally friendly alternative by eliminating the need for electricity during operation and minimizing carbon emissions. Crafted from natural clay, they are biodegradable, locally sourced, and require significantly less energy to manufacture than conventional cooling appliances.

Their production also supports traditional pottery communities, preserving valuable artisanal skills while encouraging sustainable local economies. By choosing clay coolers, homeowners reduce their environmental footprint with a cooling solution that balances ecological responsibility with everyday comfort and long-term sustainability.

Designed by Simon Pavy in collaboration with the global design agency Entreautre, the low-tech terracotta cooler offers a sustainable alternative to conventional air conditioning by combining traditional cooling methods with advanced fabrication techniques. The product is built around a porous terracotta vessel filled with water, using the natural process of evaporative cooling to lower surrounding air temperatures. Inspired by centuries-old cooling practices from the Middle East, India, and Egypt, the cooler channels warm air through precisely designed openings, where contact with the moist terracotta surface naturally cools the airflow. Its elegant geometric form improves cooling efficiency through carefully engineered airflow dynamics.

To maximize performance, the designers employed ceramic 3D printing to create complex, organic forms that increase the interaction between air and the wet terracotta surface. Developed using Grasshopper and Rhino 3D, the parametric design allowed precise control over thickness, porosity, and airflow for optimal cooling. The prototype was produced using a specialized terracotta 3D printer created by Dutch artist Olivier van Herpt, enabling intricate ceramic fabrication impossible through conventional methods

3. Modern Designs for Contemporary Interiors

Modern interpretations of clay coolers extend far beyond their traditional appearance, making them suitable for today’s refined interiors. Designers are experimenting with sculptural forms, textured finishes, earthy colors, and modular designs that complement contemporary architectural styles. Instead of hiding these cooling systems, homeowners display them as functional art pieces that celebrate craftsmanship and natural materials.

Whether placed in living rooms, courtyards, balconies, or open-plan homes, clay coolers contribute to a warm and organic design language. Their combination of beauty and performance reflects a growing appreciation for products that merge sustainability, cultural heritage, and sophisticated interior aesthetics.

Ant Studio’s Beehive, designed by architect Monish Kumar Siripurapu, is an innovative evaporative cooling system that reinterprets traditional earthen cooling methods for modern, energy-conscious environments. Developed in response to rising urban heat conditions, the system uses porous terracotta modules arranged in a honeycomb-inspired structure. Water is absorbed into the clay and slowly evaporates, naturally reducing surrounding air temperature without electricity or chemical refrigerants. Drawing from cooling practices used in ancient India, Egypt, and other hot climates, the Beehive merges cultural intelligence with contemporary architectural thinking.

Made entirely from terracotta, the Beehive is a zero-plastic, zero-emission system that also supports air purification through moisture-driven biofilm formation on its surface. The design is modular, repairable, and adaptable to different site conditions, making it suitable for factories and high-heat work environments.

4. Healthier Indoor Environments Through Natural Cooling

Beyond reducing energy consumption, clay coolers contribute to healthier indoor living conditions by providing gentle, naturally humidified cooling. Unlike conventional air conditioners that often dry indoor air and require chemical refrigerants, clay coolers maintain a more balanced indoor atmosphere through natural evaporation. This can create greater comfort in dry climates while reducing dependence on mechanically cooled environments.

Their quiet operation also minimizes noise pollution, promoting a calmer and more relaxing home environment. When combined with cross ventilation, shaded openings, and other passive design strategies, clay coolers help create interiors that prioritize environmental sustainability and occupant well-being.

Nature assigns a role to every organism, even those humans often dismiss as pests. Scavengers return waste to ecological cycles, while termites despite damaging human structures build complex mound systems that regulate airflow and maintain stable internal temperatures. This hidden intelligence in termite architecture inspired TerraMound, a cooling system designed by Rameshwari Jonnalagedda. By studying how these structures achieve passive ventilation, the project translates biological efficiency into a human-centered approach to sustainable cooling that responds intelligently to rising temperatures without excessive energy use.

TerraMound operates on two principles and that is maximizing surface area and enabling porosity. Its geometry replicates the internal networks of termite mounds, increasing air contact through a surface-area-to-volume ratio. Produced using clay-based 3D printing, it forms intricate porous structures impossible to handcraft. A water reservoir at the top releases moisture through terracotta, while a base fan draws air upward, intensifying evaporative cooling and creating a functional, sculptural biomimetic system.

5. The Future of Climate-Responsive Home Design

The renewed interest in clay coolers reflects a broader movement toward climate-responsive architecture that values passive design over energy-intensive systems. Architects are increasingly pairing clay cooling with courtyards, green roofs, thermal mass walls, rainwater harvesting, and natural ventilation to create homes that remain comfortable while consuming fewer resources. These integrated strategies show that sustainable architecture does not always require advanced technology, but often benefits from revisiting proven traditional practices.

As cities confront rising temperatures and environmental pressures, clay coolers represent a meaningful intersection of heritage, innovation, and ecological responsibility, offering a timeless solution for resilient modern homes.

The Nave Air Conditioning System is a low-tech cooling product that uses terracotta’s natural evaporative properties to regulate indoor temperatures without electricity or complex electronics. It is designed as a passive climate solution where water stored inside a porous clay structure gradually seeps through the walls and evaporates on the surface. This process absorbs heat from the surrounding air, helping cool both the material and the room. With zero emissions and no power requirement, Nave offers a sustainable alternative to conventional air conditioning systems, especially for hot climates and off-grid or low-energy spaces.

The product is available in floor-standing and wall-mounted modular forms, allowing flexible placement in homes and interiors. Once filled with water, it begins working immediately as the moisture moves through the terracotta body and evaporates naturally. Its porous structure and patterned grill design enhance airflow and surface cooling efficiency. Beyond functionality, it also acts as a sculptural interior element, integrating passive cooling technology into everyday living spaces.

As climate-conscious design continues to evolve, clay coolers bridge tradition and innovation with remarkable simplicity. They offer an elegant, low-impact approach to creating comfortable, energy-efficient, and environmentally responsible living spaces.

India’s Anthill House Has No AC and Stays Cool Anyway

Posted on by

We’ve been building houses wrong. Not structurally, not legally, and not in any way that’s easy to name. But somewhere along the line, the conversation around home design shifted away from how does this building breathe toward what does this building look like on a feed. That’s why The Anthill, a new brick residence in Ahilyanagar, Maharashtra by Kaushal Tatiya Architects, feels like such a pointed correction. Not a provocation. A correction.

The premise sounds deceptively simple: a house modeled after an ant mound. Not the insect itself, but the engineering intelligence of what it builds. Ants have been solving thermal regulation, cross-ventilation, and spatial hierarchy problems for millions of years, with no blueprint, no software, and no electricity required. Kaushal Tatiya, the firm’s founder, described the anthill not as a literal form but as “an intelligent climatic organism,” one able to “regulate temperature, create ventilation through voids, and function through a network of interconnected chambers without any imposed geometry.” That single observation is what the entire project is built on, and it shows.

Designer: Kaushal Tatiya Architects (Photos by Avesh Gaur)

The house sits low in the landscape, almost terrain-like, its exposed brick facade functioning as much as an environmental filter as it does a structural shell. From the outside, it reads as deliberately introverted: solid walls and perforated surfaces that hold back the glare before it ever reaches the living spaces inside. The real architecture begins once you start moving through it. Rooms branch off from larger communal volumes, ceiling heights shift unexpectedly, and natural light arrives filtered and softened rather than harsh. The passage between spaces becomes the experience, not just a means of getting from one room to another.

This is a design principle modernism largely traded away in favor of open-plan everything and maximum sight lines. The Anthill doesn’t make that trade. Its stepped terraces and alternating balconies recall the traditional Indian rooftop concept of the chhat, creating layered, shaded thresholds that do the cooling work before the sun reaches the interior. A 12-foot cantilevered slab, supported through brick in compression, adds a more deliberate architectural gesture to the otherwise organic composition.

It’s worth pausing on the sustainability side of this project, because it earns more than a passing mention. The Anthill operates entirely on passive systems: cross ventilation, thermal mass, and shaded courtyards. No mechanical ventilation. In a region defined by extreme heat and intense sunlight, that isn’t a compromise. It’s a design strategy that trusts the building’s own intelligence. The idea that architecture should outlast any power grid it’s connected to feels increasingly important, and The Anthill makes that case without saying a word about it.

I think what gets undersold in conversations about sustainable design is how genuinely radical simplicity is. We’ve normalized a model where buildings are essentially sealed boxes, then mechanically conditioned to be habitable. That approach is energy-intensive, expensive, and fragile in ways we rarely acknowledge. The Anthill argues the opposite: that a building designed with enough spatial intelligence doesn’t need to fight its climate. It learns to negotiate with it instead.

The visual language of the project carries all of this without being heavy-handed. The brick is warm and earthy, the curves are organic without being theatrical, and the overall effect is of a building that looks like it belongs to the land rather than placed on top of it. Photography by Avesh Gaur shows a house that reads differently from every angle, which is always a sign that the architecture is meant to be inhabited rather than just photographed.

What The Anthill ultimately puts on the table is a question worth sitting with: what if the most intelligent design move isn’t to add more technology, but to study what natural systems already perfected? The answers, in this case, are sophisticated enough to build a house around. We talk a lot about future-proofing design. The Anthill is a case where the most forward-looking move was to look at something ancient.

Stop Chasing Shade: Sony REON Pocket Plus Brings the Cold to Your Neck

Posted on by

Staying comfortable outdoors during a heatwave has always been a matter of seeking shade, chasing air-conditioned spaces, or resigning yourself to a slow, sweaty defeat. Portable fans help somewhat, but they cool the air around you rather than you directly. As wearable technology continues to push into everyday life, the idea of a personal climate device that goes wherever you go no longer feels like science fiction.

Sony has been quietly building exactly that kind of device since 2017, and the REON Pocket Pro Plus is its latest and most capable version. Rather than blowing cold air, it absorbs heat from the base of your neck using the Peltier effect to chill a metal plate against your skin at precisely the spot where blood vessels run closest to the surface.

Designer: Sony

The headline upgrade this generation is a pair of independent thermo-modules that alternate in intensity rather than running together at a fixed output. One ramps up as the other scales back, sustaining cooling without burning out quickly. The result is an advertised 20% improvement over the previous model, amounting to about a two-degree Celsius reduction at the point of contact, a modest number that feels surprisingly significant in practice.

Supporting that is an updated algorithm that reads both skin temperature and environmental conditions in real time. In Smart Cool mode, the REON Pocket Pro Plus reacts on its own as you step from an air-conditioned office into the afternoon sun, or vice versa. A quiet internal fan keeps heat dissipating efficiently, and an automatic shutoff steps in before the device gets too warm.

Fit has also been rethought. Sony’s Adaptive Hold Design uses new neckband fins to press the cooling surface consistently against your skin even as you walk or shift position, reducing the contact interruptions that were a known weak point of earlier models. The air vent that pokes above your shirt collar is now tiltable too, so it doesn’t snag on tighter or thicker fabrics.

The kit includes a second-generation Pocket Tag, a compact sensor clip that monitors ambient temperature and humidity separately from the main unit. That extra layer of environmental data helps the device make smarter adjustments than it could by reading the skin alone. A companion app lets you dial in personal preferences manually, though the REON Pocket Pro Plus doesn’t depend on your phone to function.

It isn’t strictly a hot-weather gadget. Smart Warm mode provides four adjustable heating levels, making the device a reasonable companion tucked under a winter coat as well. Battery life holds up to 10 hours on the second-highest cooling setting, which comfortably covers a full day of outdoor commitments. For longer stretches, the lower cooling levels push that figure considerably further.

The REON Pocket Pro Plus retails for £199 in the UK and around €220 across Europe, with a US launch expected in summer 2026 through Sony’s online store. It’s the sort of gadget that sounds impractical until you’re stuck on a packed commute in July with no airflow. At that point, a small metal plate on the back of your neck starts to sound rather genius.

This Laptop Stays Cool by Asking You to Move Your Own Keyboard

Posted on by

Laptop thinness has always been a trade-off dressed up as progress. The slimmer the chassis, the less room there is for the thermal infrastructure that keeps processors from throttling, and that compromise has long passed as the cost of portability. Inventec’s VeilBook, a 14-inch concept under 10 mm thick, took home an iF Design Award 2026 by rethinking not the materials but the physical behavior of the person using it.

The defining feature is a detachable keyboard that doesn’t stay fixed at the front of the deck. Most laptops position those fans beneath the keyboard, which occupies the upper area of the deck, and the keyboard itself limits how freely air can escape upward. Removing that obstruction improves airflow enough to keep the processor and memory from throttling under sustained load.

Designer: Inventec

At rest, the keyboard covers the touchpad and palm rest, leaving the vent area above the cooling fans completely unobstructed. When you do need to use the touchpad, you can simply lift the keyboard and place it toward the back, a more natural position as far as traditional laptops are concerned. You can keep the keyboard there or put it back over the touchpad, depending on your needs and workflow.

That repositioning comes with a catch. To get the best thermal performance out of the VeilBook, the touchpad has to stay covered. If a workflow runs on keyboard shortcuts or an external mouse, that trade-off barely registers. For anyone accustomed to resting their palms beside the touchpad while typing, or reaching for it mid-sentence, it’s a more disruptive ask than the concept’s clean renders suggest.

When the keyboard stays back and the touchpad is exposed, it doubles as a shortcut surface, a secondary input layer available without requiring a full posture shift. The VeilBook also incorporates behavior-linked power management, tying energy consumption to actual usage states rather than running at a fixed profile. When the keyboard is stowed and input activity drops, the system scales back power draw, which at least means the thermal compromise isn’t a constant condition.

What the VeilBook makes visible is a problem the industry has spent years papering over. Thin laptops throttle partly because keyboards sit on top of vents, and the obvious fix, moving the keyboard, apparently needed a concept award to surface. Whether blocking the touchpad is an acceptable price for better sustained performance is a question every potential user will answer differently, depending on how much of their day actually runs through that glass rectangle.

A Swiss Designer Just Replaced Your HVAC System With a 500-Year-Old Pot

Posted on by

We spend a lot of time looking forward when it comes to solving the climate crisis. Better batteries, smarter thermostats, AI-optimized HVAC systems. And sure, some of that will matter. But I keep finding myself more drawn to designers who have the nerve to look backward, who dig through centuries of human ingenuity and ask why we ever stopped doing things that clearly worked. Salla Vallotton is one of those designers, and her project Celcius is one of the most compelling arguments I’ve seen for ancient technology dressed in modern form.

Celcius is a terracotta-based heating and cooling system developed at ECAL in Lausanne, Switzerland. At its core, the idea is almost absurdly simple. Terracotta absorbs heat slowly and releases it gradually, which means in winter it can soak up warmth from a small source and radiate it back into a room for hours. In summer, the same material’s porosity allows it to draw in water, and as that moisture evaporates from the surface, it pulls heat from the surrounding air. It’s the same physics behind why sweating cools you down. One object, two seasons, zero complexity.

Designer: Salla Vallotton

What strikes me about this project isn’t the material science, which is well-established and has been for centuries. It’s the framing. Vallotton isn’t presenting Celcius as a nostalgic throwback or a craft exercise. She’s making a pointed observation about how we’ve organized our relationship with the spaces we live in. Buildings account for nearly 40 percent of global energy consumption, and in cold climates like Switzerland, heating eats up a disproportionate share of that number. Yet our systems remain stubbornly split: fossil-fuel heating that shuts off in June, air conditioning that kicks in to replace it. Two separate infrastructures for one continuous problem. Celcius merges them.

I think the cultural dimension is what elevates this beyond a clever prototype. Vallotton looked at the Alpine masonry stoves called Kachelofen, those massive ceramic structures that didn’t just heat a room but organized life around them. People understood how they worked. They could maintain them, repair them, build their daily rhythms around their cycles. There was a literacy to domestic technology that we’ve almost entirely surrendered. Today, our heating and cooling systems are hidden behind walls, managed by apps, and serviced by specialists. We’ve traded understanding for convenience, and I’m not sure we got the better end of that deal.

That’s the tension Celcius sits in, and it’s the reason the project sticks with me. It’s not anti-technology. It’s anti-invisibility. Vallotton places her terracotta system in the room as a physical, sculptural presence, something you live with rather than forget about. There’s a quiet radicalism in that choice. At a time when every product wants to disappear into the background, to be seamless and ambient and smart, here’s an object that insists on being seen, touched, and understood.

Of course, Celcius is still a prototype, and I don’t think Vallotton is claiming it will replace your furnace. The project operates more as a provocation than a product, a proof of concept that opens up questions rather than closing them. What if domestic infrastructure were legible again? What if the objects that regulate our comfort also had aesthetic and cultural weight? What would it mean to actually understand the systems that keep us warm?

These aren’t rhetorical questions. As European summers grow hotter and the pressure to decarbonize intensifies, the search for alternative thermal strategies is becoming urgent. And while the tech industry races to build ever more sophisticated solutions, projects like Celcius remind us that sophistication isn’t always the answer. Sometimes the most radical move is rediscovering something we already knew.

I find that idea genuinely exciting. Not because I think we should abandon modern engineering, but because the best design has always known how to hold the old and the new in the same hand. Vallotton does that with remarkable clarity, and Celcius is better for it.

The future isn’t flying cars – it’s blanket-shaped air conditioners. As temperatures rise and ACs become increasingly necessary in homes, a Japan-based company has figured out how to turn something as benign as a blanket into a cooling device. The Infinity Cool Blanket is simultaneously a high-tech and a low-tech piece of bed decor. It’s low-tech in the sense that it’s quite literally a fabric blanket that you wrap yourself in as you sleep, but the high-tech aspect about it is its ability to cool you down by 15°C. The innovation lies in the blanket’s material, which promotes rapid heat absorption and dissipation, pulling the warmth from your body and emitting it quickly into the atmosphere. The result feels similar to being in a cooler room, as if you had your air conditioner on. Sweat evaporates in an instant, leaving you feeling breezy and comfortable even in the hot summers… without racking up an electricity bill.

The secret lies in the Infinity Cool Blanket’s high-performance cooling fibers. These specially crafted materials are embedded with sensors that respond to your body’s heat and moisture. As your temperature rises, the fibers activate, creating a noticeable cooling effect. This ensures a comfortable sleep environment throughout the night, no matter how much you toss and turn. But that’s just half the story – It employs innovative insulation technology to block external heat while effectively wicking away sweat and moisture. This double action prevents you from feeling stuffy or damp, ensuring a consistently cool and dry sleep experience. Multiple tests actually show a drop in body temperature up to as much as 15°C when using the Infinity Cool Blanket. The blanket has a clever way of adjusting your body’s temperature to bring you to a more comfortable state, no matter what the outside temperature is.

No Need For AC With Instantly Dive into -15°C Cooling

The Infinity Cool Blanket is designed with both comfort and convenience in mind. The lightweight, breathable fabric allows for maximum airflow, preventing you from feeling weighed down. The stretchy fabric cocoons you in coldness, and its natural anti-bacterial nature means you can use the Infinity Cool Blanket for weeks before it needs a wash. When it does, just toss it into the washing machine like you would a regular blanket. The fabric’s quick-drying feature ensures it’s dry and ready to use within hours of coming out of the dryer, and an anti-pilling treatment keeps the blanket soft and comfortable even after multiple washes, while the reinforced edges prevent fraying for long-lasting use.

The Infinity Cool Blanket is versatile enough for both indoor and outdoor use, making it a valuable companion for camping trips or simply relaxing in your backyard. It comes in a single size, big enough for one person, and even ships with a carrying pouch, just in case you want to take it with you on your travels.

RedMagic VC Cooler 5 Pro attaches to any phone using magnets or clips

Posted on by

As smartphones become more powerful, the need to keep them from overheating becomes even more critical. Relying on simple heat dissipation is no longer enough, and sometimes even the more advanced passive cooling solutions, like vapor cooling chambers, are unable to compensate as well. This is especially true for phones used to play games, whether they’re formal gaming phones or just high-end models that have enough muscle but not the right cooling systems. RedMagic, nubia’s gaming sub-brand, believes that the answer lies in an external accessory, and it is now sharing that technology with others so that they, too, can benefit from it, even if they don’t have a nubia or RedMagic phone.

Designer: RedMagic

Smartphones generate a lot of heat when pushing their capabilities to the limit, and this causes not only discomfort but also degradation in performance, not to mention potential safety hazards due to the volatile battery powering the device. Unlike laptops and especially desktops, you can’t fit a reasonable cooling system inside a very thin phone, especially if it involves fans or more liquid. Delegating that to an external accessory is certainly possible, but the effort to attach and detach that gadget might be too much of a hassle.

The RedMagic VC Cooler 5 Pro remedies that by utilizing a feature that’s becoming more common among smartphones these days: magnetic wireless charging. This small squarish block can attach to any smartphone that supports this feature, which of course includes Apple’s MagSafe. What’s interesting is that RedMagic isn’t making it exclusive to these phones only, thanks to an optional back clip that can attach to any smartphone, making the VC Cooler 5 Pro almost universally compatible with all models.

But why would you want to stick or clip a small box onto the back of your phone? The RedMagic VC Cooler 5 Pro includes a 7-blade fan 3,060 sq. mm. vapor chamber liquid cooling plate that helps further pull the heat away from the phone and, consequently, away from your fingers. RedMagic claims it can drop the phone’s temperature by as much as 1­°C, though your mileage may vary.

Rather than just offering a simple fan and cooling plate, RedMagic is unsurprisingly advertising the use of some AI to automatically adjust the VC Cooler 5 Pro’s speed. This feature, along with the customary RGB lighting controls, is available through RedMagic’s “Goper” app. Unfortunately, this is only available on Android, so while iPhone owners can still use the cooling add-on, they won’t be able to take advantage of AI-powered dynamic settings as well as custom RGB lights. The RedMagic VC Cooler 5 Pro launches on April 15th at 59 EUR ($64) for the magnetic version and 64 EUR ($69) with the optional back clip.

Laptop cooling system concept extends its back to let air flow even better

Posted on by

Laptops today have become quite powerful beasts, capable of handling AAA games and even multimedia creation that their predecessors would choke at. But with great power comes great heat generation, the bane of CPU performance and battery life. Keeping a laptop cool has been a very big puzzle for laptop designers, mostly because of the problem of squeezing an efficient cooling system inside an extremely thin chassis. There are many existing solutions available today, ranging from extra large fans to vapor cooling chambers, but this particular concept offers an additional level of thermal management where a portion of the laptop’s rear extends to facilitate better airflow to and from the internals.

Designer: Wistron

Laptop cooling systems might come with different names and gimmicks, but they all function with the same principle. You draw heat away from the processors and battery and blow out the hot air while simultaneously drawing in cooler air. Whether it’s passive cooling with vapor chambers or active cooling with fans, proper airflow is still a critical element in the system. Unfortunately, due to design requirements, laptop air vents are actually small and too few.

This design concept tries to fix that problem by almost literally opening up a part of the laptop in order to create more and bigger openings for air to pass. Dubbed “dynamic airflow,” the design has one part of the laptop extend and move, exposing more vents for better airflow. In this case, it’s the back of the laptop that moves further back once you open up the lid. Conversely, that rear panel retracts again as you close the lid.

This moving part can house the laptop’s “heat module,” which can be, for example, small fans that move the air around. Normally, thermal cooling systems are placed on top of the laptop’s motherboard, which ironically leaves little room for the air to flow. Separating this thermal component not only frees up more space for airflow, it also makes it theoretically possible to make the laptop even thinner with this arrangement.

Of course, it’s easier said than done, as the design will also have come with its own consequences. For one, it makes the laptop design more complicated with more moving parts and mechanisms to extend and retract that component, which, in turn, could introduce structural compromises and new points of failure. Given the company behind the design, we might actually see this dynamic airflow concept tested in the wild by some major laptop manufacturers, which will then give us a better handle on how effective the solution really is.

Raspberry Pi Water Cooling Kit is weird, cute, and probably overkill

Posted on by

While 3D printing blasted open the doors for creatives to bring their designs to life, the Raspberry Pi can be credited for empowering not just makers and modders but also a younger generation of budding engineers and scientists by giving them access to a cheap, small yet powerful computer. The single-board computer or SBC has become the basis for many electronics projects and DIY solutions, ranging from smart home security systems to out-of-this-world “cyberdeck” computers. The Raspberry Pi 5, the latest and so far most powerful model available, does have certain performance limits, but you can overclock its processor to really squeeze out all that you can, at the expense of overheating the board, of course. The tiny computer will then need some cooling system, but this particular kit tries to take lessons learned from desktop PCs and apply them in an effective but honestly comical manner.

Designer: seeed studio

Water cooling is a well-known solution used in desktop computers to prevent the system from overheating while keeping the processor operating at maximum efficiency. Of course, water doesn’t actually touch the sensitive electronics but draws heat away instead. Cool water travels toward the hotter areas while the heated water travels away from the hot spots and gets cooled by something like a fan. Given the space required to safely and effectively implement it, it’s no surprise that this system is usually only found on large desktop towers.

Compared to those gargantuan computers, the Raspberry Pi only has a fraction of the power but it can still be pushed to the limit by overclocking its CPU. The most common solutions in the market are small heat sinks and tiny fans that provide passive and active cooling, respectively, but some might feel that those just aren’t enough. For really power-hungry setups, this water cooling kit made especially for the Raspberry Pi 5 will probably suffice, if not actually excessive.

The Water Cooling Kit is easily more than five times the size of the small board computer, composed of a water tank and a large fan that cools down the hot water. This contraption is connected to a Raspberry Pi via two silicone hoses, one for hot water and another for cool water, with a radiator sitting on top of the Raspberry Pi’s processor. This kit supposedly halves the temperature of an overclocked Raspberry Pi 5 down to a toasty 37C, depending on the load.

But, yes, you will have to sacrifice a lot to have such a water-cooled Raspberry Pi, starting with the $120 price tag. While the kit can work with multiple Raspberry Pi boards to maximize the cooling efficiency, you’ll have to buy the extra hoses and radiators to make that work. You also definitely lose the Raspberry Pi’s biggest benefit, its small form factor that allows it to be used in almost any project imaginable. Then again, some of those projects do require pushing the small computer to its limit, at which point you might need something over-the-top like this.

OnePlus 12 teardown reveals what it takes to keep this phone cool

Posted on by

Smartphones today are practically small yet powerful computers that you can hold in your hand and fit in your pocket. And just like any computer, the more powerful it is, the more heat it generates. In the past, smartphones could get by with simple cooling techniques that didn’t take much engineering or design to implement. Of course, those no longer work today, and sometimes even the common “vapor chamber” isn’t enough to keep the device from running hot. That’s why you’ll often hear brands boasting about some new advanced cooling technology, and a teardown of the new OnePlus 12 shows just how far some have to go to make sure your phone doesn’t turn into an incendiary device, whether you’re gaming, browsing the Web, or even simply charging it.

Designer: OnePlus (via JerryRigEverything)

It’s probably debatable whether the OnePlus 12 is the most powerful smartphone in the market to date, but it is one of the first to launch with the shiny new Qualcomm Snapdragon 8 Gen 3 processor. Benchmarks do speak in its favor, which suggests that despite its rather classy appearance, the OnePlus 12 is a gaming-worthy device. This also means it is in even more need of a more effective cooling solution compared to gaming smartphones with insane designs that include a tiny fan inside.

OnePlus does talk about a “Dual Cryo-velocity Vapor Chamber Cooling System,” which is just its fancy way of saying that its latest flagship has a ginormous cooling system. That size is mainly due to actually having two vapor chambers on top of each other, acting as redundant cooling systems that work doubly hard to keep not just the processor cool but the battery as well. Of course, you wouldn’t actually see the stacked vapor chambers even from the teardown, because they’ll just look like a large, flexible copper plate.

The size of this material, however, does show the almost ridiculous lengths designers and engineers have to go through to ensure the safety of such a powerful device. And it’s not just because of the powerful processor but also thanks to super-fast battery charging, which means even more heat being generated. The teardown also shows the trick that OnePlus (and other manufacturers) use to pull off this quick charging feat: split the battery into two and charge both small packs at the same time.

Although not the focus of the video, the teardown does suggest how relatively easy it is to open up the OnePlus 12. It was only when it came to separating the screen did things got really risky, but if you’re trying to replace the display, chances are it’s already dead in the first place. OnePlus is noted to have a solid parts replacement program, so much of that effort in prying open the OnePlus 12 won’t be in vain.
