Wristify thermoelectric bracelet makes heating and cooling personal

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

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

Graphene gets even cooler

For a two-dimensional material, graphene is certainly punching above its weight in terms of potential applications. Already set to enable faster, stronger and foldable electronic devices, researchers claim that the single layer lattice of carbon atoms can also help keep electronic components up to 25 percent cooler, giving it the potential to significantly extend the working life of computers and other electronic devices.

Icicle-like Chillsner keeps your beer cold from the inside out

While beer is best served chilled, everyone who’s tried it knows that beer and ice generally aren’t a good mix. Most options to keep the beer cold once out of the fridge, like beer koozies or the Chill Puck, work from the outside in, but a new device called the Chillsner turns things around. This freezable metal spike fits inside a beer bottle to keep your brew ice cold from the inside out. Read More

Nano-engineered panel passively cools buildings by emitting heat into space

Studies have already shown us how white-painted roofs can help cool buildings by reflecting sunlight, while "green" roofs beat the heat by blocking sunlight and providing a source of evaporative cooling. Now, a team of scientists from Stanford University have created a panel that not only reflects sunlight, but it also draws heat from within the building and emits it into outer space. Read More
