BioSkin defies urban heat island effect to help keep buildings cool

By - July 24, 2014 9 Pictures
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.

Coca Cola uses the sun to cool drinks

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

Tado turns "dumb" air conditioners into smart, energy-saving devices

By - May 22, 2014 7 Pictures
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.

Adidas' metallic Climachill apparel cools athletes in hot conditions

By - April 15, 2014 11 Pictures
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

NASA's Cold Atom Lab to make the ISS the coldest spot in the Universe

By - February 13, 2014 4 Pictures
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

Your next fridge could keep cold more efficiently using magnets

By - February 13, 2014 3 Pictures
The fridge is the most common of common household appliances. Despite improvements in efficiency over the years, they remain one of the biggest users of electricity in the home, relying on chemical refrigerant and a compressor to transfer heat from the inside to the outside of the fridge. GE researchers have now developed a new type of refrigeration technology using magnets that is more environmentally friendly and is predicted to be 20 to 30 percent more efficient that current technology ... and it could be in household fridges by the end of the decade.

RD House keeps naturally cool inside a Dominican Republic hillside

By - February 12, 2014 27 Pictures
Cave homes, pit houses and other part or fully-underground dwellings all offer benefits in energy efficiency when compared to typical above-ground homes, thanks to natural insulating properties that help to maintain a near-constant interior temperature. Architectural firm Vasho made use of the same principle to keep RD House cool by partially burying it within a steep Dominican Republic hillside. Read More
