The first time I ever saw a propane powered fridge was in the Amish community in Lancaster ( they are not very fond of electricity) Absorption chillers are used where large amounts of waste heat is present also. The one that sticks in my head was a the AC in a local supermarket was powered by the condenser heat from the freezers, they were essentially getting an AC free ride.

The major difference between this set-up and a typical propane fridge is what they are calling a solar compressor on what appears to be lowside which would speed the recovery up considerably
