The Georgia Institute of Technology has plopped its robotic dragonfly drone up on Indiegogo to be crowdfunded. It's a pretty impressive device: a four-winged, superlight flier with the capability to hold a camera, plus GPS, Wi-Fi, and compatibility with smartphone apps. But one of the coolest ideas comes from the dragonfly itself: the tiny, 6-inch Robot Dragonfly can glide like an insect rather than having to constantly flap to hold itself aloft, like the Parrot AR.Drone 2, so its battery life reaches up to half an hour. (Comparatively, that's a lot.) You can snag one for as low as $100 if you fund now--apparently it'll retail for more than twice that. Check it out here.
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.
