An alternative solar operated refrigerator in which the refrigerator itself is also of "conventional" design, involves solar thermal conversion using high temperature solar energy collectors. The high temperature thermal energy produced may be transformed subsequently into mechanical energy via a heat engine, which then drives a refrigerator compressor.
