Using the cars' weight to generate energy

Kinetic energy is not a new subject on this blog. I've already shown you how this kind of technology can be used to generate enough energy to power some parts of a nightclub or more simply, your MP3 player.

This time I bring you a great idea developed at a Sainsbury's supermarket in Gloucester, United Kingdom. This supermarket has installed kinetic plates in the parking lot that use the weight of shopper's cars to pump a series of hydraulic pipes, which in turn drive a generator. The figure below is quite self-explanatory:


Apparently, the kinetic system can generate enough energy to power the store's checkouts. While it may not seem as much, it sure is a great step towards a more green attitude.

Here's another picture at location:
