I designed this Smokeless Stove that uses inexpensive, non-fossil fuel made from vegetative and wood waste.
It also works as a geyser on the side, giving you running hot water while you or the people living in the flats below you are doing their cooking. It would be an ideal solution for the multistoryed slums that the government is now building in many cities in the country, and would benefit hundreds of thousands of poor people living in slums. It can also be used in villages—changing the whole paradigm of rural cooking.
