Photovoltaic cells are one of the more promising alternative energy sources. Mechanically they are very simple, with no moving parts, and are clean and emission-free. Unfortunately they are also inefficient. One of the reasons for this is that they overheat, a problem that a Stanford University team under electrical engineering professor Shanhui Fan is addressing with the development of a thin glass layer that makes solar cells self-cooling.  Read More

A custom heat exchange system built into the lid of IcyBreeze blows out chilled air

The need for an ice cold drink tends to go hand in hand with stinking hot temperatures. And while a chilled beverage can help to soothe from the inside, nothing brings on sustained comfort like a blast of cool air. The team behind IcyBreeze is looking to refresh from all angles with a cooler that works as a portable air conditioner, putting to use the ice-cold air inside.  Read More

Booze Joulies, once frozen, are claimed to be 'colder than ice'

If the only beer that you have on hand is tepid, you may be tempted to pour yourself a glass and throw in some ice cubes. As any connoisseur will tell you, though, ice cubes in beer is a definite no-no – as the ice melts, it dilutes the drink. That's where Booze Joulies come into play.  Read More

The urban heat island effect, whereby the high concentration of heat-retaining concrete and bitumen causes metropolitan centers to be significantly warmer than the rural areas surrounding them, is a common problem around the world. The phenomenon is particularly prevalent in Tokyo, Japan, but among the sea of towering structures stands one beacon of hope. The BioSkin that coats the NBF Osaki Building integrates evaporative cooling to keep its surface temperature down and could inspire new solutions to rising city temperatures across the globe.  Read More

Based in Tehran, the Sharifi-ha House by Iranian architectural firm Nextoffice is a luxurious home by anyone's standard. The seven-floor residence boasts an elevator, swimming pool, and a sizable gym. More interestingly, it also features three rooms which resemble large wooden boxes and sit upon operable rotating platforms.  Read More

The Bio Cooler in sun-baked Aipir, Colombia

In the town of Aipir, Colombia, the temperature can often get as high as 45ºC (113ºF), yet few of the residents have a reliable source of electricity. So, pulling an ice-cold beverage out of the fridge isn't really an option. Coca Cola and the Leo Burnett Colombia advertising agency therefore devised a "Bio Cooler" for the town – it reportedly chills cans of Coke, without using electricity.  Read More

As internet-connected appliances continue to make their way into the modern home, you'd probably think that cooling your house with a smart air conditioner would involve going out and buying a new one. German company Tado is looking to bring your existing unit up to speed with its Tado Cooling system, a Wi-Fi-enabled device that turns any old air conditioner operated by infrared remote control into a smart device.  Read More

Adidas' new Climachill fabric gives athletes a cool-down

The sports apparel market has no shortage of solutions for cold weather, with waterproof-breathable materials, advanced natural and synthetic insulations, and battery powered heat among them. But athletes have fewer options in hot, humid weather: take off clothing, get a cold headband/cloth, or stop exercising and find an air conditioner or pool. Adidas offers one more. Its new Climachill fabric combines several cooling elements to keep athletes more comfortable during hot summer sessions.  Read More

Layers of clothing that cool you down rather than warm you up can involve lugging around hefty equipment or some pretty advanced technology. The IceTee takes a more low-tech approach with strategically-placed pockets for holding gel packs to help keep you cool.  Read More

Quantum physics likes the cold. In particular, macroscopic quantum phenomena such as superconductivity, superfluidity, and Bose-Einstein condensates (BECs) are only found at quite low temperatures. While current refrigeration methods can attain temperatures of a few nanoKelvins, attaining still lower temperatures is largely prevented by the need to support the cooling matter against the pull of Earth's gravity. Now NASA's Cold Atom Lab, scheduled for installation on the ISS in 2016, will aim for temperatures roughly four orders of magnitude smaller.  Read More
