Energy saving madness

Sainsbury's brings green power to the checkout with 'kinetic plates' (Guardian, Monday 15 June 2009)

In other words, it creates energy out of nowhere. Right.

"Hey you guys, let's drive our Hummer 30 miles to Sainsbury's and pass over the kinetic road plates! To save energy!"
