Plant oil stove

With the development and construction of a plant oil stove that resembles a conventional camping stove, researchers from the field of Agricultural Engineering in the Tropics and Subtropics of the University of Hohenheim succeeded in a breakthrough:

Plant oil stove in action
The stove, which runs with plant oil, prevents the health hazards of cooking with open fires and helps to reduce the enormous demand for firewood. It is operated quite simply and burns different plant oils clean and efficiently. Moreover, this innovative stove has proven its practice value and durability in various field tests. It is planned to being produced at the approximate cost of € 30 per unit in the developing countries where it is used. The plant oils required as fuel can be produced locally using relatively simple pressing and filtering processes.

Technology for developing countries
With the new stove and 100 liters of plant oil, an average family can cook an entire year under healthy conditions. The stove functions without smoke, increasingly scarce and expensive fuel such as wood, charcoal or kerosene are no longer required, and 370-times less carbon dioxide is emitted than is the care with open fires. Additionally, the stove brings increased safety by being absolutely explosion-proof. Highlight of the development is a specially designed vaporizer and an impact plate. A manually operated air-pump generates the compression that carries the plant oil into the vaporizer where it passes through the heat of the flame. The gaseous fuel escapes through a borehole from the vaporizer, is mixed with air and burns in a hot flame.
