Four Cooking Stove Designs That Can Save The World
At the front of both the design of high quality low cost stoves and a robust distribution network is Envirofit out of Colorado State University. Their diligent work in developing combustion chambers that meet precise tolerances to maximize combustion has lead to a family of stoves, lead by the flagship G-3300. The stove uses a special low cost, high heat tolerant alloy that, along with a advanced combustion chamber design, reduces fuel consumption by 50 percent.
Designing the stove was only half the work though. Envirofit has opened up offices throughout the world to developed distribution and credit networks to get the stoves to where they are needed. They are on target to sell half a million of the $23 stoves by the end of 2011.
Stovetec in partnership with Aprovecho Research Center 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.
