Homebrew Protos Plant Oil Stove




After reading with interest all about the Protos plant oil stove and seeing the potential in the burner I took it upon myself to recreate the burner part of the unit.




Some things I changed for simplicity are on the vapourising element I only have one feed from the oil supply, the other end I have capped. My test unit is constructed from Micro bore 8mm copper tube, unsuitable for long term use but easy from a fabrication point of view.




I managed to create a 0.5mm hole by reaming out the tube with a drill bit and then pecking through the final copper tube with a sharp nail.




I placed my Protos burner into my Turk burner unit previously fabricated and connected it to my oil supply via a peristaltic pump at 0.5L per hour delivery.




Igniting was achieved with the help of a propane blow torch, this easily got the unit up to working temperature.




My Protos clone is in (Alpha) testing right now and I will bring some more details on how it performs in due course.

Protos plant oil stove for developing countries

A stove powered with plant-oil? That does not seem so unusual in an age in which even automobiles run on rapeseed oil. But, a high-tech, high-quality stove that is nevertheless so inexpensive that even poor families in developing countries can afford it, is a special challenge that requires a special idea. The plant-oil stove Protos, developed by BSH, is more than just a cooker; it is also generates positive ecological, economic, health and social benefits beyond basic humans needs of daily food preparation.
More than 2.5 billion around the world prepare food on open fires. Up to 700 kilograms of wood are needed per person per year to fulfill the cooking requirements, leading to severe deforestation, health and safety problems. The World Health Organization WHO estimates that every year 1.6 million people die as result of the indoor air pollution caused by those fires. Furthermore deforestation leads to ecological problems like flash floods and mudslides – as seen recently in the Philippines and elsewhere.
BSH is working to provide a viable alternative to the open fires, charcoal use as well as imported kerosene or gas used for cooking. With a core competence in developing world-class home appliances, BSH is dedicated to sustainable development for all members of society.
But, BSH cannot tackle this challenge alone. Support for the initial research and development in conjunction with the University of Hohenheim was provided by the German Environmental Foundation and other members of the Bellagio Forum for Sustainable Development.
On the ground, BSH is working in cooperation with the Leyte State University in the Philippines as well at the German GTZ and DEG and European Environmental Heritage Fund.
