UAV Hoisted Tower Powered By Laser Over Fiberoptic
carstene writes "LaserMotive, winners of the 2009 NASA power beaming contest, has a new invention, a virtual comm or surveillance tower. It's a quadcotper that can run indefinitely, powered by laser beam over a fiber optic cable. This allows the "tower" to reach great heights and avoids most laser safety issues."
Atlanteans had this tech back in the 10,000 BCs except they didn't bother with a tether, they just beamed their maser (that's Microwave amplified...) energy through crystals seated on top of large pyramidal buildings. We're so 20,000 years ago.
