produces a hybrid wood and charcoal stove that is based on a special lightweight clay core which improves combustion efficiency but maintains strength for years of use. A special dual chamber allows families to use either wood in the upper chamber or charcoal
in the lower one. The double door system also allows for more control of the burning, leaving both open to maximize air intake when starting a fire and partially closing the lower door to maintain the proper temperature.
The technology is dubbed the rocket stove, a seemingly simple device that has a large vertical cylinder to hold a pot and an opening at the bottom to feed the combustible biomass to efficiently cook a meal or pasteurize drinking water. While the concept has been proven to be simple, effective and best of all cheap, studies in fluid dynamics, geometry, and advanced materials are leading to very efficient high-tech designs which can reduce the smoke by 95 percent.
Add to that the fact that fuel consumption is reduced by half, which helps to curb expenses for families and slows the clearing of forests just for cooking fuel. All of theses factors make these stoves essential for the long term sustainability of a significant portion of the world population. These stoves are precision technologies that are far superior to homemade stoves, and they are designed to be affordable for even the poorest in the world with prices as low as $15 a unit.
