For nearly three years we have been working with and achieving very good results with the Solar Steam Cooker. The Solar Steam Cooker cooks food without using any fuel (except sunshine) and with no harmful emissions. I suppose solar cooking in general takes care of the no fuel and no harmful emissions part, the Solar Steam Cooker overcomes some important cultural issues that are inherent in conventional solar cooking. The Solar Steam Cooker is best suited for groups of people like (boarding) schools, hospitals/health centres (besides cooking food for patients it can also be used to sterilize instruments), and refugee camps like those found in the Darfur region of Sudan and elsewhere in Africa and around the world. I think this device could radically change the way food is cooked in the developing world.
