We have seen and felt rumble strips on the road, well now they could be producing more than just bone shacking vibrations through your car, they could be producing electricity to power street lights etc. The idea is being tested at a Civic Centre in Roanoke, Virginia, USA, the rumble strips were operated by cars leaving the centre and by the end of the day around six hundreds vehicles had gone though in six hours producing enough power to light an average home for a day!
According to the company, New Energy Technologies Inc;
“Once fully optimized and installed, engineers anticipate that MotionPower devices may be used to augment or replace conventional commercial electrical supplies used to power roadway signs, street and building lights, emergency power storage systems and other electronics, fixtures and devices.”
