If your video store isn’t already six feet under, XStreamHD will finally put it there. The company is launching the first set-top system able to download movies that are the exact quality of Blu-ray discs: 1080p high-def, near-flawless images, and 7.1 surround sound. Subscribers can rent or buy 200 best-selling titles starting this month, with the full high-def film and TV catalogs of all major studios not far behind.
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.
