A simple sixteen-brick fuel-effcient stove

An example of a two-door manufactured fuel-effcient stove.

Fuel-effcient wood stoves can be valuable companions to solar cookers as part of the Integrated Cooking Method. Some can be easily constructed from low-cost materials such as bricks and concrete blocks, while other designs are offered as finished manufactured stoves.

They burn small pieces of wood or other biomass very efficiently, greatly reducing the amount of fuel required. The fire burns very hot, which eliminates much of the smoke typical of open fires.

Although the level of smoke produced is reduced, there is still a risk of respiratory illness when used indoors, or with the constant attention required to feed more fuel to the stove.

The Ben 2 Firewood Stove

  • May 2015: Dieter Seifert reports: Today I have made tests with the Ben 2 and Ben 3 Firewood Stoves. It is almost unbelievable, but the efficiency is always higher than 40% and if one does not heat up too fast (i.e., the power under 1.5 kW is), the result is almost no smoke and approximately 350 g thin wooden sticks can bring 6 liters of water to a boil in 25 minutes. Of course cooking is much more convenient with a large parabolic solar cooker (We have used the AlSol 1.4 for many years.). The Ben ovens are so easy to prepare (2 sheets provided with holes and bending, drilling a ring and three legs and turn, turn 4 bars hairpin-shaped and assemble everything) that the cost in firewood crisis regions would be well below $10 USD. The combination of heat-retention cooking and Fuel-efficient wood stoves with the solar cooker is ideal. The solar cooker can do much more than just cooking. It is a peace-creating technology that is so urgently needed.
