=== Protos the Plant Oil Stove<br/> ===
 
−
 
 
−
The University Hohenheim (Germany), in cooperation with '''Bosch and Siemens Home Appliances Group (BSH)''', developed protos the plantoilcooker. The basic idea was to develop a cookstove that can use a variety of plant oils; even recycled and filtered oil previously used for frying.
 
−
 
 
−
Field tests in the Philippines and in Tanzania have shown that households and small enterprises such as restaurants, that were previously cooking on 3-stone fires, can handle the Protos-stove. People stated that they enjoyed the comfort of cooking and said it was like cooking on gas, even if LPG was not available. Based on observations from the field tests, BSH developed a 'second generation' of the protos plantoilstove technology to increase efficiency, reducing noise, cleaning time and the cost of production.<ref name="https://energypedia.info/wiki/Stove_by_BSH_%28protos%29">https://energypedia.info/wiki/Stove_by_BSH_%28protos%29</ref> The serial production was launched in May 2010 in Indonesia. Initial costs were considered to be around&nbsp; US$40 - 42, at a production rate of around 25,000-50,000 units in 2010.<ref name="http://stoves.bioenergylists.org/taxonomy/term/1687">http://stoves.bioenergylists.org/taxonomy/term/1687</ref>

However, in 2012, BSH decided to conclude the Protos plant oil cooker project and to discontinue series production of the stove in Indonesia. The main reasons were as follows:<ref name="http://www.bsh-group.com/index.php?109906">Protos Plant Oil Cooker Project to Conclude. http://www.bsh-group.com/index.php?109906</ref>

−
*The stove was required to be of a high quality, safe and as easy as possible to use. Equally, however, it had to be cheap enough for people in developing countries to be able to afford it. The low purchasing power of the potential users had limited the use of the stove to a few individual projects.
 
−
*Plant oil cookers require a lot more cleaningn and maintenance than kerosene stoves as plant oil leaves residue in the burner when it evaporates.
 
−
*Due to the physical properties of plant oil the stove is technically complex. All varieties of plant oil have an extremely high flash point, which means that plant oil stoves require much higher operating temperatures and a longer pre-heating process than conventional stoves burning fossil fuel.
 
−
*No established market for sustainably cultivated plant oil in Indonesia.
 
−
*BSH faced serious difficulties in setting up a supply chain for sustainable cultivated plant oil.

Introduction

Stoves fueled with alcohol (ethanol and methanol) are not widely used in households. They are mainly used in areas where such stoves and fuels have been fostered and promoted by studies and projects.


Cooking with Alcohol Stoves

A stove to burn alcohol fuels can be very simple. It can be made relatively cheaply in countries with industries producing articles such as aluminium pots, etc.


The main components of the burner are shown here[1]:

RTENOTITLE


Alcohol stoves have a very clean combustion, emit no soot and negligible emissions. Cooking is very fast as heat is available instantly after ignition of the fuel.

For further advantages and disadvantes of alcohol as a fuel see also the article onCooking with Ethanol and Methanol.



Experiences of Cooking with Ethanol Stoves

The most documented ethanol stove model is the CleanCook Stove by CleanCook Sweden AB, which is produced in South Africa and promoted mainly by Project Gaia.

The "CleanCook" Stove is available as a single or double-burner model for households and institutions. It is made from aluminium or stainless steel. The CleanCook is a non-pressurized alcohol stove with a refillable fuel canister of a capacity of 1,2 liters.[2] The canister contains a porous fiber that adsorbs alcohol and retains it in a manner that prevents spills, leaks, fires and explosions.[3] The power output per burner is rated at 1.8 kW at maximum heat, allowing for a cooking time of 4-5 hours. It can burn ethanol and methanol.[2]

Up to now, 55,000 cleancook stoves have been provided, mainly in Africa.[4]

Project Gaia and its Ethiopian sister organization, Gaia Association, have lab and field tested alcohol stoves since 2005. To date, alcohol stoves have been used by households in Ethiopia, Nigeria, South Africa, Malawi, Madagascar, Mozambique, Vietnam, Brazil and Haiti. Click here to access country study/project reports. The largest number of households using alcohol stoves is in the UNHCR refugee camps near Jijiga, Eastern Ethiopia where more than 4,000 households rely on the CleanCook stove and ethanol fuel as their main source of energy. The UNHCR now aims to scale up to provide ethanol cookstoves and fuel to up to 27,678 households by 2017.[5]

Project Gaia currently leads four community-based, small-scale ethanol distillation projects in Ethiopia. Also in Brazil and Haiti microdistillery projects are being implemented. These projects aim to allow communities to produce clean cooking fuel using local feedstocks, simultaneously adding value to agricultural markets by taking advantage of co-products of the distillation process[6].

One of the pioneering efforts in use of low concentration ethanol for cooking and lighting [7][8] was done in early 2000s by Nimbkar Agricultural Research Institute[9] in India.
