B/S/H BSH Bosch und Siemens Hausgeräte GmbH has decided to continue the Protos plant oil cookstoves that they had been working on in Indonesia, and instead made the technology publicly available for commercial manufacturers:
The family of plant oil stoves, including the Protos stoves, were designed to be safe, and reliable cookstoves for low income residents of Indonesia. BSH found that despite having a lot of plant oil available, there was no reliable network of distribution of that oil, and it was keeping users from being able to use the stove. The plant oil stoves also require a lot more cleaning and maintenance than kerosene stoves. Between the difficulty in getting fuel, and the additional maintenance, it was difficult to expand the stove project beyond the initial pilot projects, and BSH eventually concluded that this project was unfeasible.
