Your only hope is the gas refrigerator, called the Electrolux refrigerator. It was invented by two Swedes while they were still undergraduates! This refrigerator does not use mechanical input to operate, just a high-temperature source. If 650F is high enough I have no idea.

Kerosene-burning refrigerators were popular last century in homes with no electricity supply. The modern equivalent uses refillable cylinders of camping gas. http://en.wikipedia.org/wiki/Absorption_refrigerator

If there is one big attraction of electric fridges it's that they kill far fewer people than do the combustion fridges. Kero and gas fridges can cause house fires, and they can also kill people by carbon monoxide poisoning when poorly maintained operation occurs in a confined space (house, caravan, etc.)
