Plant Oil

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.

An Update from BSH on Protos. The Plant Oil Stove.
Samuel N. Shiroff, Director, BSH

For a brief update BSH is preparing a mass production capacity that should come on-line in late autumn of this year. Initial production will be ramped up through Q4 so we can expect to produce several thousand units in 2009. We are working with a local Indonesian partner - in an OEM process with 100% local content. This is part of our goal, but since BSH is not present in any meaningful way in our conventional business in that country, it is a very new activity for us. Thus, the time line may be subject to delay if quality or other issues arise. I would rather delay a few weeks than deliver a defective product.

The initial cost is going to be around US$40 - 42 Ex-works. This means it does not include transport or tolls if moving outside of Indonesia. Our total capacity for 2010 should be around 50,000 units - so this price will hopefully edge down. Naturally currency fluctuations will also play a role. BSH is running the project as a "social business". This means our goal is simply to cover costs and any additional profit will be put back into the project - for instance subsidizing costs in countries where there is viability, but not enough purchasing power for the capital costs. The mentioned price is the cost of production and local overhead. No more. Larger orders do not generate greater discounts. At first all orders will be filled out of Indonesia. New production capacity requires a minimum annual demand of 25,000 units and a viable infrastructure in the desired region. With perhaps the exception of the tank and some cleaning tools, it is simply not possible to establish small-scale local production that ensures consistent quality in an economically viable manner.

ARISTO. The Plant oil stove

Two Burner ARISTO StoveTwo Burner ARISTO Stove

With the purpose of developing a stove that uses a different fuel to petroleum and other conventional, 4 years ago was initiated the development of an alcohol stove, which presented several problems in its efficiency such as:

A. Under performance in the generation of heat energy
B. High cost of fuel (alcohol)
C. High levels of evaporation of alcohol, which generated a minor use
D. Smell of alcohol due to its evaporation
E. Danger in use because of the high level of inflamability of alcohol in their natural state

With these results has been decided to seek other fuel that could solve these problems.
During 4 years we have researched and developed a stove that is capable of generate the same or better performance that gas stoves have and could solve the drawback of accessibility to gas in rural areas and areas far from cities.
To that end we developed a stove that works with vegetable oil, whose characteristics are presented below.

3. Description

Aristo is a 2 stove burners that operates using all kinds of vegetable oil.
The most known types of oils are Higuereta, jatropha, Camelina, African palm.
They can also be used cooking oils made of soybean, maize, sunflower, although these are not desirable because of its high cost and are also products consumed at home.
Another excellent option is the use of used cooking oil, which has a high performance at low cost.
The stove oil has a good performance on fuel consumption.
Compared with the gas generates a decrease of 40% in costs

Features and Benefits

1. Easy to use and fast ignition
2. High level of heat energy
3. Danger void, because the oil only lights inside the stove
4. Do not emit toxic gases.
5. The oil is not volatile, so you do not need special packaging
6. No need of heavy and expensive storage tanks
7. The oil can be obtained at any point of sale, in small packages
8. In the fields can be sown to extract oil for own use
9. It reduces the import of liquefied gas which would generate large benefits to the country.
10. They can be used as heaters in cold regions.
11. This produces a savings of up to 70% in costs compared with gas.
12. It helps preserve the environment by reducing the felling of trees used as firewood for cooking.
13. The oil stove is much more economical than a gas stove.

The press extracts oil from sunflower, sesame, and other oil seeds. The filter produces clear, cold-pressed, nutritious cooking oil ready for sale or consumption. The seedcake by-product is valued as a high protein animal feed supplement.
