How’s this for clever: Using a parking lot to generate power. Sainsbury, a supermarket in Gloucester, England, has installed kinetic plates in the parking lot that use the low-speed travel of vehicles to pump a series of hydraulic pipes. Those pipes drive a generator. For those of you who slept through physics class, this is called piezoelectric power. It’s the same technology Formula One cars use to convert the kinetic energy gathered when braking into power later. If used on a wider scal
