The Protos Plant Fuel Stove: Cooking with Coconuts

We've talked before about the Institute for Agricultural Engineering in the Tropics and Subtropics of Hohenheim University, Germany, when highlighting solar food driers. And we’ve brought up the issue of deforestation of the Philippines for palm oil. In this case the two coalesce. The Institute observing that open wood fires using forest timber are less than 10% efficient, worked on a new stove. One that allows for effective cooking, while leaving trees intact. Their creation was a plant oil stove running on coconut oil. The operation of the stove sounds very much like that of modern, multi-fuel, backpacking stoves. It uses some fuel to preheat the stove valve, which releases a vaporised oil/air mixture. Aside from coconut, it is expected the stove will also take other pure plants oils like Jatropha and Canola. Seems that in pinch it will run on kerosene and diesel as well. The prototype (see photo after fold), currently under evaluation in the province of Leyte, Philippines is said to be capable of being made from materials readily available in developing countries. The project is being supported with assistance of Western Europe’s number one appliance powerhouse: BSH Bosch und Siemens Hausgeräte GmbH.
