I was reading that, at least, propane could be used to replace the AC refrigerant. http://en.wikipedia.org/wiki/Propane and there was an interesting gas-absorption refridgerator with no moving parts that can cool directly from heat energy. http://en.wikipedia.org/wiki/Gas_abs...n_refrigerator -- ASCII stupid question, get a stupid ANSI |
