Electro-kinetic Road Ramp
The electro-kinetic road ramp is a method of generating electricity by harnessing the kinetic energy of automobiles that drive over the ramp. In June 2009, one of the devices was installed in the car park at a Sainsbury's supermarket in Gloucester, United Kingdom, where it provides enough electricity to run all of the store's cash registers. The ramp was invented by Peter Hughes, an electrical and mechanical engineer who is employed by Highway Energy Systems Ltd. The company says that under normal traffic conditions, the apparatus will produce 30 kW of electricity. Other proposed applications for the road ramps include powering street and traffic lights, heating roads in the winter to prevent ice from forming and ventilating tunnels to reduce pollution. The idea was dismissed as ''Talk of 'kinetic energy plates' is a total waste of energy'' in the Guardian by David MacKay, a professor of natural philosophy in the Department of Physics at the University of Cambridge The Univer ...

Sainsbury's
J Sainsbury plc, trading as Sainsbury's, is a British supermarket and the second-largest chain of supermarkets in the United Kingdom.

Gloucester has a population of around 132,000, including suburban areas. It is a port, linked via the Gloucester and Sharpness Canal to the Severn Estuary. Gloucester was founded by the Romans and became an important city and ''colony'' in AD 97, under Emperor Nerva as '' Colonia Glevum Nervensis''. It was granted its first charter in 1155 by Henry II. In 1216, Henry III, aged only nine years, was crowned with a gilded iron ring in the Chapter House of Gloucester Cathedral. Gloucester's significance in the Middle Ages is underlined by the fact that it had a number of monastic establishments, including St Peter's Abbey, founded in 679 (later Gloucester Ca ...
