Sainsbury's Rolls Out Kinetic Energy Generator | GreenBiz.com: "The new system, which has been developed by U.K. startup Highway Energy Systems, works using plates that move when vehicles drive over them, creating enough kinetic energy to drive a generator. The technology is expected to produce 30kW of energy an hour without causing any disturbance to motorists as they drive over the plates."
