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

Review: EntroSys BikeAir motorcycle A/C system

By - February 10, 2014 19 Pictures
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

NASA develops MacGyver snorkel for astronauts

By - December 21, 2013 6 Pictures
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.

Bedjet heats or cools your bed with a blast of air

By - December 18, 2013 4 Pictures
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

V-Tex could be the "microwave cooler" that you wish existed

By - October 29, 2013 5 Pictures
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

Wristify thermoelectric bracelet makes heating and cooling personal

By - October 24, 2013 2 Pictures
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

Cold transport trucks to cool their cargo using fuel cells

The refrigeration units used in cold transport trailers are typically powered by small diesel engines, which use up non-renewable fuel and release greenhouse gases, just like their big brothers. The US Department of Energy, however, is looking into an alternative. As part of a two-year pilot project, it’s equipping four such trailers with clean-running hydrogen fuel cells. Read More

O2 Cool hydration backpacks offer both sipping and cooling mist

By - August 5, 2013 5 Pictures
Wherever you weigh in on the global warming debate, it would seem that folks are hotter than ever this year. Misting and cooling products have been a trend over the past few months, with launches of products like the Aquabot and Q-FOG. The self-assigned leader in cooling products has decided to get in on the action with its own twist on the theme. It's incorporated a misting system into a line of hydration packs, so the reservoir of water on your back can both quench and cool. Read More
