The parking lots of shopping malls in the U.S. contain loads of cars in the car-parks.On parking customers generally switch off the engine after a short period (NOT GOOD FOR THE ENGINE!)and stroll in to do some browsing/shopping.It would be better for the car engines if they were left idling. Perhaps a conector of some type coud be made to hook up with the alternator output from the car.If the car's battery were fully charged up the current coud be switched to the local grid of the Shopping Mall.The MALLS would benifit from reduced electricity costs,the shoppers' car engines wear and tear is reduced.Shoppers could be encouraged to use such a system by awarding them credits towards purchases at the Mall.

Reward: The use of an untapped source of energy supply & longer engine lifetimes for motorists.

Midoh, letting the engines of hundreds of cars run for no particular reason would waste a lot of energy, plus, the air on the parking lot would be so disastrous that you could only approach your car with a gas mask.
