Are solar ovens affordable in the developing world?
Not by the people who need them the most – virtually nothing is. However, there are now durable, efficient modern designs which can retail for $50 or less. There are continuing efforts to reduce that cost further. Creative financing will always be necessary to achieve the widest possible distribution. This includes micro banking, lay away plans, barter arrangements and subsidies. And since solar energy is free, people eventually pay for their ovens with the money they have saved by reducing their need for traditional fuels.
