Solar Cookers That Work at Night

Rob Goodier at Engineering for Change reports on progress in solar cookers for rural areas in the Third World. At least that's where they were originally intended for. Now in the Age of Trump, all bets are off.

H. S. Udaykumar, a mechanical engineering professor at the University of Iowa, explains the challenge like this: “First, the cooker should operate in the early morning and late evening when the sun is not at peak. They should be able to cook indoors, sitting down. They cook for two hours each time. The stove top temperature should be about 200C, with heat delivered at approximately 1 KW to the cook surface.
