[Stoves] new manufacturing technique for GEK(gasifier experimenters kit)

[Crispin Pemberton-Pigott]

Very Interesting John. Very interesting.

We are working 'at pace' on what appears to be a new understanding
(advance?) of ceramic components and you might be able to get the small
chambers really hot at the sides. I take your point about the cooling
effect, which could be expressed in terms of the outside surface area of a
cylinder relative to the volume.

As the volume gets smaller, the bleed-in air gets lower on the sides, yes?

What burn rates do you think are sustainable on a small scale?

What is see is that some projects in Johannesburg and Ulaanbaatar are aimed
at improving the houses (reducing heat demand) and others are improving the
stoves (delivering more heat per kg of coal).  They don't talk to each other
much.

By the time the stoves are perfected, the houses won't need nearly that much
heat!  Sort of humorous.

I think 2-3.5 kw will do well for most small homes, whereas now they need
5-8 kw.

Challenged to make a 3kw heat source with low CO, would your present
dimensions work?

Best regards
Crispin

Jim and Crispin,

Absolutely fantastic plan and a guideline for my coal stove plans, to be 
published soon.
