Not content to harvest wind energy from atop a static tower just a few hundred feet tall, Altaeros has demonstrated an aerostat wind turbine that can be lofted up 1,000 feet from a trailer, no tower necessary.
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.
