Really good info! I am looking into this now. I really wouldn't be that hard, if would for sure have to be DIY, but a large solar collector that is used for heating in the winter now doesn't have to not be used in the summer, you could use the extra to power a refrigeration cycle.
OR could you directly heat the propane (refrigerant) in a homemade high pressure solar collector with a check valve allowing flow only in the discharge direction? Would that create flow? I KNOW you could get it hot enough to make huge pressure differences.
