[Stoves] Stoves Digest, Vol 23, Issue 7

[David Osborne]

Dear Lloyd, 

Maybe the answer lies in the question, to improve something that is truly practical and cultural isn't the answer, the answer could lay in the way that it is used, look at the Jompy boiler, as you know it is a device that can be added to any cultural fire with maximum effect. Our findings in Kenya and Uganda as well as India indicate that 3 stone fire will not disappear and to try and change it will just attract resistance however add a device that can save up to 60% of fuel and exposure to fumes etc with an availability of 1 litre of boiling water per minute. The Jompy is doing this now. 
Sometimes over engineering can occur  by default. Let's just keep things simple  yet effective. 

Kindest regards 

David Osborne.
