Kinetic Energy From Roads
An Israeli company Innowattech have developed a road that produces energy every time a car is driven over it! This is because the road surface has piezoelectric crystals built into it, which vibrate whenever a vehicle passes over the surface. This is what produces the energy, which is then fed into transformers.
The amount of energy produced is only small, it works out at about four hundred kilowatts per kilometre, but imagine the power produced if all of the world road surfaces where covered in this material, the savings would be colossal. Although it would depend on the cost if this is to be practical. Innowattech will be testing a hundred metre stretch of road early in 2009.
