- NEW: May 2015: Dieter Seifert reports: Today I have made tests with the Ben 2 and 3 Ben 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.
