Transforming kinetic energy into electricity doesn't often get taken seriously, but at least one Burger King joint has been hooked on to the idea. The New Jersey-based outlet is set to give the first roadtest to MotionPower strips produced by New Energy, which harness energy from vehicles passing over them. Based on the thinking behind regenerative braking in hybrids, the energy absorbers are made up of small plates moving up and down. UK supermarket chain Sainsbury's recently introduced similar "kinetic road plates" in its car parks, and hopes are they'll generate 30 kW per hour from the energy and weight of cars overhead. Sainsbury's plans to power store checkouts through the scheme, whereas Burger King will just exploit your energy to power various appliances. Provided someone doesn't sue for unlawful energy appropriation and the roadtest is successful, New Energy hopes to expand the use of its power strips to other high-traffic, low-speed locations like toll booths and intersections.
