Motorists in Roanoke, Virginia got the chance to test a novel kinetic energy recovery device just by driving over a big speed bump.
As part of a real-world test of its MotionPower Express system, New Energy Technology installed an energy-recovering speed bump at the entrance to the busy Roanoke Civic Center during the weekend Roanoke hosted a gun show and circus. As cars crossed the speed bump, their tires depressed treadles that captured kinetic energy, which was converted into electricity. via autopia/Wired
