Answer 1

both of the first 2 answers are good ones and I agree with them

Answer 2

flame requires some aggressive chemical reaction, and some sort of combustible fuel, however, producing electricity or heating water are available solar technologies, one could use a mixture of hot water and solar electric powered vacuum pumps to produce steam or store solar electric energy in batteries and use that energy in electric cooking and baking.

hot water from solar heating can be used to heat homes.

Answer 3

You cannot uproot a culture just like that. People do not change that fast. There is no need for them to change to a frenetic lifestyle.

Yes, you can do something to upgrade their present mores. The population you are considering are not technically savvy. Either the system you design has to be completely maintenance free, or cheap enough not to be repaired.

None of them buy fuel. Most use waste solid material to burn.

I have been associated with a few programmes of the kind you are considering. Very few are sustainable. Try the sites below for some concepts. You can visit them or volunteer.
