Sainsbury's find a green use for cars
Paul Ridden writes: Following a successful trial at its depot in Northampton, a Sainsbury's store car park in Gloucester is getting ready to start producing enough energy to power the store's tills. The power will be generated by the action of cars rolling over kinetic plates, which have been positioned underneath road surfaces. The impressive 30kW per hour of energy produced by the plates should be more than enough to keep the tills running.
As a car rolls over the road surface, the plates produce a sort of pumping action (similar to that used by Formula 1 racing cars to turn braking energy into speed) which then drives a generator. The store in Gloucester also benefits from rainwater recycling to flush the lavs, solar panels and the cold air from the fridges is used to keep customers cool while they pay for their goods at the checkouts.
With Tesco about to install electric car charging ports at its stores in Kensington and Vauxhall, it looks like being eco-friendly will feature heavily in future trips to the supermarket!
