Silent Power PC ditches the fan for a "cool" copper afro

The Silent Power PC is claimed to be the first high-end PC able to ditch noisy electric fans in favor of fully passive cooling. In place of a conventional fan, the unit uses an open-air metal foam heatsink that boasts an enormous surface area thanks to the open-weave filaments of copper of which it is composed. The Silent Power creators claim that the circulation of air through the foam is so efficient in dissipating heat that the exterior surface temperature never rises above 50° C (122° F) in normal use.

Stanford researchers develop self-cooling solar cells

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.

BioSkin defies urban heat island effect to help keep buildings cool

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

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

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
