"Nissan cars sold in North America and Europe will feature solar chargers from ICP Solar, under a sales agreement announced Tuesday by the two companies. The chargers will serve to keep the 12-volt batteries of new Nissans charged while they are parked on sales lots."
I've actually seen some of these at car dealers by my house. They move them from car to car to keep the batteries charged so they don't have to turn the engines on with the current price of gas.
