Oil Stove

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.

GTZ Probec Protos Stove Tests Tanzania

To give feedback on the Bosch-Siemens PROTOS plant oil stove when using Jatropha oil:

To give feedback on the Bosch-Siemens PROTOS plant oil stove when using Jatropha oil:
The long term test of the Jatropha oil being used in the BSH stove is currently under way in Tanzania in cooperation with GTZ-ProBEC. Preliminary tests are giving very positive results, even though with Jatropha oil being produced on small scale. Purity of the oil seems to play a crucial role, but we will be able to tell more early 2007.
The stove is designed for using straight plant oils, no need to convert them into Biodiesel. However, Biodiesel can also be used.

Plant oil-powered stove catches Gloria’s fancy
Manila Standard Today, Philippines, May 19, 2006

President Gloria Macapagal Arroyo yesterday ordered the mass production and distribution of a new cooking device that runs on oil harvested from plants to 18 “hotspot” urban poor areas all over the country.

Mrs. Arroyo said the Leyte State University should fast track the production of Protos, which can run on jatropha oil, among other plant-based oil products, to help Filipino consumers cope with the rising cost of living.

“We will support the mass production and distribution of this cooking oil in 18 hotspots in the country to benefit those living in urban poor areas,” she said.

The Leyte State University is producing Protos, which is manufactured by German firms Bosch and Siemens Home Appliances Group.

Mrs. Arroyo said while the introductory price at P2,000 may be considered prohibitive, mass production will eventually lower the price of the plant oil-powered appliance.

Protos, also known as jatropha stove, was officially launched in Malacañang yesterday.

The President also ordered the immediate release of P500 million for the Philippine National Oil Co. for the planting of jatropha plants, locally known as tuba-tuba or tubang-bakod.

Socioeconomic Planning Secretary Romulo Neri said the country imports about $7 billion worth of oil and petroleum products, 25 percent of which is diesel. Once the jatropha methyl ester product is mass-produced, it can translate to a savings of $1.75 billion.

The PNOC and the Armed Forces have signed an agreement for the conversion of idle lands in military camps into plantations for jatropha, a potential biofuel source.

Another P500 million will be sourced from National Development Co. for the mass production of jatropha cooking oil and jatropha methyl ester as an alternative gasoline blend.

Lt. Gen. Romeo Tolentino of the Northern Luzon Command said 150 hectares have been allotted by the Armed Forces for the test planting of jatropha.

The Camarines Sur provincial government has also set aside 10,000 hectares of land in the towns of Lagonoy, Caramoan, Presentacion, Pili, Calabanga and Sipocot to serve as jatropha farms.

According to Jun Lozada, president of the Philippine Forest Corp. which is a subsidiary of the Department of Environment and Natural Resources, about P50 million of the P500 million PNOC budget will be used for further research.

“Per hectare, a jatropha farmer can earn P10,000 to P15,000 for the first year, and after five years that will plateau at P60,000 per hectare,” Lozada said.

Neri, however, gave a conservative view on the private production of jatropha oil products. “Let’s give it one year with the Philippine Army first. I do not want to be overoptimistic because this is still in the testing stage although some people are making glowing remarks over this.”

Jatropha planted from seedlings would start yielding fruits after six months, while those planted from cuttings would have an earlier yield at one to two months.

The University of the Philippines-Los Baños is now developing the protocol for the tissue culture of jatropha to mass produce the plant cuttings.

UPLB aims to come up with a high-quality jatropha seedling that is free from viruses, bacteria and fungi.
