[Stoves] [Jatropha cake properties]

[Tom Miles]

Crispin,

Good thoughts. The Jatropha discussion was "toxic" in that it stimulated
quite a lively debate. We probably got more heat from the discussion than
from the stove on a cold and slightly windy day. No pot. It clearly needs
some careful testing. Good project for Winter stove camp (this week?)  

I didn't bring either of my testers. Unfortunately my TSI is in repair
(after burning it up testing a gasifier) and my Testo is in use at a steam
boiler. Stovers don't seem to carry them. I would have liked to have tested
the two Aprovecho charcoal stoves that were demonstrated. 

Tom

Dear Tom

Thanks to Tom, Dr Tom and Dr Paul

Did you put a pot on it? I am interested in whether or not the flames
touched the pot more than usual. That has to be judged by someone who knows
the stove and other fuels well. If the fuel is oilier, will it make the
flames longer to the point that they run along the pot creating more CO?

It may be that a J-seed stove needs a different flame path length to get
great performance.

Burning Jatropha seed in a Tom Reed Woodgas Stove at ETHOS 2011. No
emergency vehicles were called and no adverse symptoms were recorded by
observers. Greatest danger was that the seeds "pop" occasionally. 

Thanks to Paul Anderson for the demonstration.
