Dr. Dieter Seifert has been called "the father of the parabolic solar cooker". He is the developer of the SK line of parabolic solar cookers and helps many organizations with these. Dieter promotes use of deep focus, high quality cookers together with heat retention cookers. Over 16,000 SK's have been produced.
Recent news and developmentsEdit
- 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.

- May 2013: Pioneering couple reflect on the state of solar cooking - For almost forty years, Imma Seifert has been involved in the promotion of solar cooking technology. She has used all the solar cooking devices that her husband Dieter Seifert has designed. Seifert’s solar cookers are today used by thousands of people around the world. For 157 days during 2011, Imma cooked all meals for her family in Germany using the 1.4-meter parabolic SK-14 solar cooker. On many of these days she baked bread and cakes, produced jam and made fruit juices. She combines solar cooking with the use of a retained-heat cooking device. On all sunny mornings, she brings ten liters of water to a boil and keeps it hot for use during the day and evening in an insulated retained-heat container (studies have shown that 1/3 of the energy needed for cooking is required simply to bring water up to a boil). Imma and Dieter are convinced that quality solar cookers are not only helpful in overcoming the firewood crisis, but can reduce poverty in developing countries. They believe that solar cookers should also be used in industrialized countries and have proposed a large solar cooking program in Spain, where currently 50% of the youth are unemployed. They also urge schools to teach solar cooking not only as a clean energy technology, but also as a symbol of global cooperation and sustainable development.
