A group of Israeli engineers have created a system that allows certain types of roads to generate electricity just by driving over them. The Israeli engineers behind the project claim that a 1km stretch of the power-generating asphalt will generate 400kW - enough power to run eight small cars.
The system works by embedding tiny piezoelectric crystals into the road. When cars drive over the crystals, they are 'squeezed' and thus generate a small electrical charge. The new 'electric road' will be tested next month when engineers in Israel drive over a stretch of tarmac embedded with the tiny piezoelectric crystals.
