Cooling

Megan and Emily, creators of the IceTee that applies cooling gel packs to particular point...

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

Artist's conception of a quantum atomic gas undergoing laser cooling in an ultracold refri...

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

A bottle of beer is cooled using the new magnetic refrigeration system developed by GE

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.  Read More

The rear sections of the RD House come into direct contact with the hillside, so are natur...

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

Road testing the EntroSys BikeAir motorcycle A/C system

As someone who likes to have my skin wrapped around my body rather than smeared up and down the highway, I cringe every time I see a motorcyclist cruise past without suitable protective gear on. There is an (albeit still completely flawed) rationale behind this, though – leather jackets, boots, gloves and scrape-resistant pants are hot, heavy and uncomfortable. All of this leaves motorcyclists in an unfortunate predicament because when the weather is at its best, the inclination to pull on protective gear is at its lowest. The EntroSys BikeAir motorcycle A/C system is a product designed to let you enjoy the best of both worlds by providing portable cooling (and heating) for the rider. It sounds great in theory, but does it work? We ventured out under the burning Australian sun to answer that question.  Read More

Putting a snorkel on a space suit seems about as daft as making water wings for a meerkat, but that’s exactly what NASA has done. It isn’t some bureaucratic error, but a serious piece of life-saving engineering inspired by an incident in July, when an astronaut on the International Space Station (ISS) almost drowned in his own helmet when water started leaking in. Now faced with urgent repairs due to a faulty cooling system, NASA has come up with a quick fix, so a team can venture outside the station in safety while the cause of the leak remains under investigation.  Read More

The Bedjet can be placed under the bed if there's room – just be sure to clean out any dus...

At this time of year, those of us living in the northern reaches of the planet once again struggle with a recurring First World problem – getting into a bed that has cold sheets. People located farther south, meanwhile, are faced with the opposite situation – getting too hot in bed. The Bedjet is designed to address both problems, while also allowing users to run their furnaces or air conditioners at lower settings overnight.  Read More

The planned home version of the V-Tex

Chances are, this has happened to you at least once ... you come inside on a hot day, open the fridge, and discover that you haven't set aside any juice/beer/pop to chill. Even if you were to put some in the freezer, it would still be at least 10 or 15 minutes before it was good and cold. "Why isn't there something like a microwave cooler?" you find yourself wondering. Well, there soon could be, in the form of the V-Tex – although it will incorporate vortexes instead of microwaves.  Read More

Most bracelets aren't likely to alter your temperature too much either way, but the Wristify isn't most bracelets. Developed by four MIT engineering students, the Wristify works on the principle that heating or cooling the skin on one part of the body can make the entire body feel warmer or colder. By creating a personal heating and cooling device, the Wristify team ultimately hopes to cut the amount of energy currently used to heat or cool entire buildings.  Read More

Gizmag presents a look at five of our favorite passively-cooled homes

Home air-conditioning offers near-instant relief from hot weather but is both expensive and resource-heavy to run. Gizmag picks five of our current favorite passively-cooled homes that are environmentally responsible to keep comfortably cool, and – perhaps just as importantly – very desirable to live in.  Read More
