My non-electric refrigerator operates along similar lines but uses a propane burner to dissociate ammonia from water in a continuous cycle. Devices such as this can operate on many different heat sources including kerosine. Absorption refrigerators have been available for over a century but they are neither cheap nor inherently safe.

My next off-grid refrigerator will be solar-electric with a high efficiency compressor. Even factoring in the cost of additional solar panels and a storage battery it will be cheaper to purchase and certainly cheaper to run.
