Dragon Power Station Harnesses Kinetic Energy From Passing Vehicles to Power Stuff

Terry Kenney's Dragon Power Station prototype works by harnessing the kinetic energy of trucks passing over plates buried in the road and turning that energy into electricity. The system he's got set up now in the Port of Oakland, with 2,500 trucks passing over it in a day, is enough to power 1,750 homes. It's a very interesting concept that can be extended to busier streets, harnessing a little bit of the energy that would otherwise be lost.

It's not all free energy, however, as these trucks slow down ever-so-slightly as they depress the plates in the road. TreeHugger supposes that this would be even better for the times when you actually do want to slow down, like going down a hill, where they could load up on these plates and slow down cars enough to not have to ride the brakes the whole way. Sounds good to us. [Treehugger]
