I am a pediatrician, living in Rio de Janeiro, Brazil. I first became interested in solar cooking after seeing a demonstration in 1992, at the Rio 92 meeting.I have a weekend house in an island about 150 km from Rio and go there at least twice monthly. Up to 1 year ago we had no electricity save for a generator that was used about 10 hours/month. Now we have solar power and can have refrigerators running full time.
My solar cooking is done on the early desined solar box, mostly for fish, rice and potatoes. It is a success and amazes the local fishermen.
I also have a solar oven, with a parabolic mirror, but the temperatures achieved are too high for general use, reaching 450º C, melting pan handles.
I plan to make a video about solar cooking but have been posponing the work.
Some vilages in the Northeastern part of Brazil would be an ideal place to disseminate solar cooking. High temperatures, lack of wood for cooking, lack of electricity in many impoverished areas.But the distances are enormous, 6-7 hours of bus riding.Before going there I would have to test the local food (goat meat, black beans, corn) and decide on cooking times and so on. A very important use would be pasteurizing water and milk.
