Dear Paul

  ...snipped...
When it comes to mass of fuel consumed, the energy in it and so on, the lab is 
agnostic. There are no holy

stoves and there are no holy fuels. The stove does what it does, emits what it 
emits, and consumes

what it consumes. We just report it. Don't shoot the messenger.

Paul replies: Sorry, but the testing centers do NOT report BOTH the FUEL consumption and the ENERGY consumption. A major point of the Shields E450c method is to show the ENERGY consumption and the ENERGY efficiency. It is the people who only talk about FUEL (and who avoid acknowledging the difference concerning energy because of the energy in the charcoal) who are the ones making the problem continue on and on and on.

When the statement finally comes about testing procedures and reporting for pyrolytic stoves that produce charcoal, I hope that the distinction between energy and fuel is clearly made AND is reported in each report of a stove tested.

Although gasifiers have existed for a long time, gasifier STOVES (especially those that yield charcoal) have not. So some changes are needed in the reporting of the results.

Paul
