My wife and I made a short video showing how we make Pita Bread using a version of this stove design. Here is the link:

My little iCan made from a 3 lbs Costco coffee can boiled 1.75 liters of water in 42 minutes this afternoon. Ambient temp was 47 [8.33C]. This was done in 5 batches averaging 350 ml each. A very clean burn. Some soot at the start of each batch when the water was cold. Just a soon as the water in the cup warmed up a bit, the soot stopped.

Of course I also made some biochar as well.

Fuel was a good quality wood pellet. Cost of fuel: about 17 cents assuming pellets at $230 per ton. They can be bought for a good deal less, but I am using a higher number to be safe.

Cost per liter boiled: ~ 7.4 cents, allowing 4 cents as the value of the biochar captured at the rate of 17.5% of the dry weight of the fuel.

a high efficency charcoal stove for small buisness's, cook wihile standing up and it has built in ash catchers. only 9,000Ksh (appx. 130$)

From Crispin: "You know the top of the Stovetec 2-door unit? It has a very thin cast iron plate which is quite cheap but you have to get them from China, about $1. Perhaps they could be made in AL from local drink cans. I don’t think anyone could melt one in normal use."

From Christa Roth:
we had the same idea in Madagascar, where pot-makers in the highlands not only make pots but all sorts of other items at low prices from aluminium. great stuff. all made with sand casting. the Swiss NGO ADES ran with the idea and started making potsupports in 2009, but I only saw the first stove in Switzerland last year (see photos). I don't know the cost but it is affordable.

please copy, it is doable! at least where you have a trade and the skills in country, which seem to be more abundant in the french-speaking countries in Africa

and I like Crispins idea to cast different pots. Let us know how things go. It might be easier to getting the pots adopted than some stoves...
regards Christa
