How did this design improve life?:
Turbo Stove - A New Cooker that Operates on Bioenergy.
Hundreds of various types of stoves made of stone, clay and sheet metal have not been able to solve the problems related to the preparation of food by women under conditions in the developing nations.

Amongst all the food shipments, tents, pots and cauldrons, there has been a distinct lack of cookers incorporating bioenergetic and other agricultural waste materials in their heating systems.
