This small wood burning cooker (pic 1) has been converted to not only produce electricity, but also run a small heating system, produce hot water for washing and can also cook dinner. With a cooking hob and a small oven this device may be the future of powering a home.
After developing electricity generating wood burning cookers for many years, it is now possible to power one hundred and twenty flood lights while dinner is cooking!
