Richard McMahon shares his experience with using a solar oven as a radiant refrigerator at night. His experiments began in the winter of 1997 in Western Australia, where he successfully created ice by leaving a box-cooker outside at night. McMahon also details his creation of a radiant fridge using a dead fridge and insulation, which keeps his food cool even during the hot summer days. He believes in the potential of radiant fridges and hopes others will adopt this simple yet effective technology. McMahon’s innovative approach to refrigeration offers a sustainable and low-tech solution for keeping provisions fresh and beverages cold.
