*{{NewApr16}}'''April 2016:''' [[Dieter Seifert]] has a new design for the tripod for the Ben 2 and Ben 3 Firewood Stoves, which has several advantages. The tripod consists of three equal parts which are welded together. The parts are made of round steel with a diameter of 6 mm. {{NewApr16}}[[Media:Alternative_to_welded_tripod_photos_drawings_and_list_of_parts_-_April_2016.pdf|Precise, illustrated instructions here...]] |

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 {{Cat|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. |
