NASA's set to test a wing concept it says "may herald (the) future" of electric planes, but it almost looks like a joke -- it has one-third the wing area of a normal aircraft and 18 electric motors. However, the space agency is dead serious about the LEAPTech wing, a joint partnership with two private aerospace companies. It consists of a 31-foot, carbon composite span with tiny motors powered by lithium iron phosphate batteries. After successful testing at slower speeds, NASA will "fly" a wing section aboard a specially-equipped truck at speeds up to 70mph. Eventually, the wing will be mounted to a commercial Tecnam P2006T aircraft and flown by test pilots.
