Well, in a manner of speaking. The idea is this: streetlights and traffic signals take lots of electricity to function -- electricity which could be generated by a special low-impact ramp, built into the road, which would harvest power from the inertia of the cars moving over it. (Sounds a bit like the tube station that powers itself, which we blogged about awhile back). Check out this video from Hughes Research and see if what you think. Would this work on American roads, or would it be annoying? (Apologies in advance for the cheesy rock soundtrack.)
