The house will be almost entirely hand-made. I like how this tutorial explains the system w/o ammonia because alcohol and hydrogen gas are much easier to understand as most DIYers have had some experience with both of these chemicals. When they throw ammonia into the mix it gets extremely confusing [also because the system now has to be pressurized]. I'm going to attempt to build a small fridge from this concept, as well as an air conditioner. The systems will be alcohol/hydrogen and the heat source will be either hydrogen flame [from my solar hho generator] or wood gas [using a simple wood gas generator]. If anyone has any advice that'd be cool. Thanks, Ian Stumbled upon this site while researching refridgeration for my off-grid home im building. The house will be almost entirely hand-made.

Propane has a better energy density than electric batteries, and it's quieter, cheaper, and simpler than using a gasoline motor to either power a generator or to drive a compressor directly. I had one of these refrigerators in a VW camper van that I owned for ten years. This is the first time I've seen such a clear explanation of the operating principles.
