0

This is how to build the ultimate OFF-GRID refrigerator from cheap and easy to find materials. This design uses both the cooling effect of evaporation, and two water cooled condenser coils. The fridge is shown using a water ram pump at the end, if you add an electric fish tank style pump powered by 12 volt/solar, it will only use 8 watts an hour.
