Best Ashden Moments 2010: Anne picks the moment GERES sold its one millionth cookstove

GERES, Cambodia - 2006 Ashden Award winner
For the fourth in our end-of-year series, where members of the Ashden team choose favourite moments from the year, Anne Wheldon, Technical Manager, picks the moment GERES sold its one millionth improved cookstove.

I was really encouraged when I found out how much one of our past winners, GERES in Cambodia, had progressed since winning an Award in 2006. Not just that the sales of their improved stove had exceeded one million, but that it was now in use in nearly half the urban households in Cambodia. That’s what we need everywhere, sustainable energy technology becoming mainstream.

Award-winning presents for Xmas: the cookstove

Run out of ideas for Xmas gifts? Why not give an award-winning clean stove to a camping enthusiast?

These highly efficient rocket stoves are a simple but revolutionary technology that burn wood or charcoal and cut fuel use by 40 percent or more, reducing smoke and carbon monoxide emissions by more than 50 percent.

Efficient stoves like these tackle one of the scourges of the developing world. Indoor smoke kills 1.6 million people, mainly women and children, worldwide every year.

In 2009 we awarded our Energy Champion prize to the Oregon-based Aprovecho Research Center and SSM in China who together design and manufacture affordable and efficient rocket stoves used extensively in the developing world. The company that has been set up to sell the stove, StoveTec, has sold over 50,000 in countries like India, South Africa and Chile. They aim to reach the three billion worldwide who cook on smoky open fires and inefficient stoves.

But these stoves are also available in the UK. Order and get more information and reviews from UK retailers: Wild Stoves (all the money goes to Stove Tec)and Bell Tents

Chris addresses delegates from 12 sub-Saharan countries on solar and stoves

Ashden Award winner Chris Mulindwa (left), from the Rural Energy Foundation, yesterday addressed 12 partner organisations from across sub-Saharan Africa on climate change and sustainable technologies.

He was guest speaker at a joint international workshop in Uganda on the shores of Lake Victoria, organised by the Baring and John Ellerman Foundations.

This was a valuable opportunity for Chris to show the effectiveness of solar and stove equipment to delegates from Mauritania, Ghana, Chad, Zimbabwe, Sudan, Ethiopia, Tanzania, Democratic Republic of Congo, Kenya and, of course, Uganda.

The purpose of the week had been to share experiences of working with displaced peoples and focus on women, rights and education. Chris wrote to us:

I am mainly going to talk about two challenges - indoor air pollution and lack of access to electricity. I will then share with the delegates some of the technologies available to deal with these challenges (efficient cook stoves and solar energy), the benefits gained from using these technologies (better health, income generation and saving and environmental conservation) and I will share with them the approach that Rural Energy Foundation has taken to diffuse these technologies (market development).

The Rural Energy Foundation won the 2010 Ashden Award for Africa, which was supported by the John Ellerman Foundation.

Andrew Marr says "We are three weeks away from a crucial conference"

Last night there was an excellent debate at the British Museum titled Conserving Biodiversity. Whose money? Whose rules?

Tonight our Senior Advisor, Anne Wheldon, gives a talk titled Stoking up a cookstove revolution: The secret weapon against poverty and climate change.

It's not hard to see the link between the two.

A significant driver of deforestation is the amount of trees cut down for open fire cooking. This leads to loss of habitat for animals, loss of native plants and soil erosion that increases risk of flooding.

2010 is the international year of biodiversity. Yesterday a report was released that said one in five of the world's plants are under threat of extinction.

The issues of biodiversity, poverty, renewable energy and climate change are all bound up in the idea of sustainability. What's fascinating about hearing this debate at the British Museum is seeing sustainability treated - quite rightly - as both an environmental and a cultural issue.

WoodGas stove demo

The following stove demonstration is by Mike Pepler, Technical Manager at the Ashden Awards.

One of the key issues in developing countries is changing the wood stoves people use for cooking so that they are more efficient and emit fewer harmful pollutants. Gasifying stoves are one area where research is still ongoing, and this demonstration is of a stove that uses a fan powered by two AA batteries. Being battery powered, this is not intended for use in developing countries, but is aimed at the outdoors and camping market in developed countries. However, some of the profits from its sale go to fund research on developing a similar stove for developing countries, but with a thermoelectric generator to power the fan.

Here's the details on how it works.
It's a WoodGas CampStove. What it does is "gasify" the wood, burning the gas produced in an efficient manner right under the cooking pot. Basically there's a cylinder inside it that you fill with small sticks:

Cookstoves in the Economist

A recent Economist article covers biomass cooking stoves, explaining some of the challenges faced in designing them and making sure they actually get used:
If user demand were the sole driver of innovation, the biomass cooking stove would be one of the most sophisticated devices in the world. Depending on which development agency you ask, between two-and-a-half and three billion people—nearly half the world’s population—use a stove every day, in conjunction with solid fuel such as wood, dung or coal. Yet in many parts of the world the stove has barely progressed beyond the Stone Age.

The World Health Organisation (WHO) estimates that toxic emissions from cooking stoves are responsible for causing 1.6m premature deaths a year, half of them among children under five years old. In China 83m people will die from lung cancer and respiratory disease over the next 25 years, according to a recent report from Harvard University. Research from the University of California, Berkeley, on stoves in India, Guatemala and Mexico has found links between indoor air-pollution from stoves and increased incidence of pneumonia, cataracts and tuberculosis.
...
Even if they get the thermodynamics and materials right, designers must also make the devices compatible with local foodstuffs and cooking habits. A lot of the initial stove projects failed this test, says Daniel Kammen of Berkeley’s Energy Resources Group, who has worked on several stove projects in sub-Saharan Africa. A lack of field testing, he says, meant a lot of stoves were simply unsuited to users’ needs. The difference in cooking styles between countries, he says, can determine how—and whether—a new stove design ends up being used.

Award winning stoves feature in DFID magazine

Two past Ashden Award winners feature in the Developments magazine, published by DFID:
A pioneering range of wood stoves and kilns in South India, which save at least 30% of fuel, have been crowned “2008 Energy Champion” at the annual Ashden Awards for Sustainable Energy.
...
Many of South India’s small businesses rely on wood as their main source of fuel, which causes pollution and deforestation as well as uncomfortable and dangerous working conditions when boilers and stoves are badly-designed. Building on the track record of stove design at the renowned Indian Institute of Science, TIDE commercialises their designs to provide efficient tailor-made wood stoves and kilns cutting fuel by at least a third.
...
The Ashden Awards Outstanding Achievement gong went to Grameen Shakti of Bangladesh, an organisation which has made a big contribution to the spread of sustainable energy solutions. So far it has installed 160,000 solar home systems and is adding around 8,000 more each month. Since winning an Ashden Award in 2006 it has diversified into the provision of fuel-efficient stoves, which improve living conditions and save fuel. It also produces domestic biogas systems which bring clean, sustainable energy to thousands more.
The full story is available here, and further details on the two winners are at the following links:

Additional photos from Kisangani Smith Group

Kisangani Smith Group (KSG) from Njombe, Tanzania, won an Ashden Award in 2008. Information on their Award-winning work with domestic stoves burning waste sawdust and agricultural residues can be found on the Ashden Awards website, along with the official media photos. However, we also have some additional photos that may be of interest, so here they are. (You can click on each image to see a larger version)
