A company in New Jersey is testing a prototype of a kinetic energy harvester that looks like a speed bump. The device, dubbed "Motion Power Energy Harvester", is installed in a drive-thru at a NJ Burger King restaurant, where cars generate electricity as they drive over the bumps and pick up their Whoppers. Pretty interesting idea.

It looks like a flattened speed bump with long pedals across the top that press down when tires roll over them. That force turns gears inside, generating 2000 watts of electricity instantaneously, according to the engineers who designed it.
