Turning Big Truck Traffic into Electricity
...
It took him eight years to get a working prototype, but now there's one working at the Port of Oakland which Kenney calls the "Dragon Power Station". Special plates are set on the road, and as big trucks drive over them (about 2,500 of them per day at the port), they compress a tank of hydraulic fluid under the road, which in turn creates a series of pumping actions that turns a generator to produce electricity.
By June, the Dragon should generate about 5,000 to 7,000 kilowatt-hours of electricity each day, or enough to power up to 1,750 homes. Not bad for a prototype.
