Oh, very cool!

…a Burger King in Hillside, New Jersey tried out the MotionPower energy harvester from New Energy Technologies to see how it would hold up to the heavy traffic flow they experienced over the holiday period. As drivers wended their way to the window to get their Whoppers, the cars ran over a metal speed-bump affair that, using the weight of the vehicles to depress a plate and turn some gears, produced 2000 watts with each passing.

As it was just an initial durability test, the fast food franchise didn’t actually benefit from the “free” electrons but customers were treated to a very small light show that was installed to demonstrate the that system was working. The manufacturer envisions larger MotionPower machines installed in places where traffic is slowing down to prevent the scheme from requiring extra energy input from vehicles. [via autobloggreen]
