When you hear that a machine is fanless, you'll probably also assume that it's not extremely powerful, likely relying on mobile-focused components that don't pack much of a punch compared to high-end desktop gear. CompuLab's latest desktop PC, the Airtop, challenges that preconception, offering 200W of completely silent passive cooling, allowing for powerful CPUs and full-size graphics cards.
In a world where lasers are sci-fi's weapon of choice for melting away an enemy spaceship (sometimes even translating to the real world), researchers at the University of Washington have swum against the current and produced the first laser capable of cooling liquids. The technology could be especially useful for slowing down single cells and allow scientists to study biological processes as they happen.
It's no secret that the amount and quality of restful sleep has a significant impact on our day-to-day well-being and long-term health. Unlike devices that merely monitor and report sleeping data, such as the Sleepace RestOn, the nuyu Sleep System takes a more active approach under the covers, by automatically changing bed temperature through the night.
Stanford engineers have developed a transparent silicon overlay that can increase the efficiency of solar cells by keeping them cool. The cover collects and then radiates heat directly into space, without interfering with incoming photons. If mass-produced, the development could be used to cool down any device in the open air – for instance, to complement air conditioning in cars.
Whether it’s slides at playgrounds or roofs of houses, there are some things that you just don’t want to heat up in the sun. Not only does it make them uncomfortable to touch, but it also causes them to age prematurely. While painting such surfaces white is one approach, a scientist at Johns Hopkins University has developed another – reflective paint made from glass.
While many athletes resort to pouring a bottle of cold water over their heads to cool down after an event, Nike's Sports Research Lab (NSRL) has something a little higher-tech in mind. The company's new hood prototype is designed to tackle the issue head-on, using liquid cooling to lower temperatures.
In an effort to improve the energy efficiency of building, researchers have sought to develop windows that change transparency to let more light – and therefore heat – through when it's cold, and less when it's hot. Unfortunately, these methods tend to impede the passage of visible light, some by tinting panes and others by complete obscuration. But a team at the Cockrell School of Engineering at The University of Texas at Austin has developed a "smart window" technology that allows the passage of visible light while blocking heat, or vice versa.
Air conditioners are a bit of a paradox. On the one hand, they're most needed in the hottest weather, but on the other, the hottest days are when air conditioners are least efficient. Mistbox is an add-on technology for domestic air conditioners that uses a water mist to pre-cool the air conditioner, increasing its efficiency and lowering energy costs.
Of all the scenarios you'd want to find yourself in a heatwave, being barefoot on a hot tin roof would be toward the bottom of the list. These exposed surfaces soak up sunlight to slowly but surely transform into corrugated hotplates, compounding the sweltering ambient temperatures and warming the living space below. But a team of Sydney-based scientists has developed a new material that's claimed capable of keeping a rooftop cooler than the air that surrounds it, saving energy and sweating residents in the process.
At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.
