Ooh! ooh! ooh!
Someone posted a link on bennelson's EV thread about a cheap vacuum pump for his brakes. The link shows how to use a fridge compressor to draw vacuum for vacuum bagging surfboards. But that got me thinkin'. How about using the entire system out of a household refrigerator to cool the car? Put the condenser under the car to dissipate the heat and the evaporator inside. Power the thing with a couple marine deep-cycles and an inverter. Like I said, I suppose I could put up with charging batteries every night. Need to get into the habit if I ever build an EV.
