Computers get hot. Heat is bad for computers. To whisk it away, we use a combination of heatsinks and fans to snatch heat away from the internals and blast it out of the computer's case. But Sandia has a concept that combines the two in a way that, they claim, increases heat-removing efficiency by up to 30 times.
For some reason, telepresence--the concept of having your person (in audio and/or video form) represented by some kind of machine while you are physically elsewhere--has lent itself to extreme goofiness. It's not really a goofy idea, and yet we've seen squishy larval phones, shoulder-mounted robots, the Anybots robot (which recently ordered coffee in a Palo Alto shop), and now this blimp-like thing from Sony that projects your face onto what's essentially a motorized balloon.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
