June 16, 2009: Kinetic Plates
Sainsbury's stores in the U.K., looking to cut costs, have built new stores with kinetic plates in the parking lot.
Cars driving over these plates cause them to deflect, and the deflection is transfered to electric generators which produce an expected average of 30kW of energy an hour. That's enough power to run all the check outs.  It all helps and they expect a 2 year payback. link link
