[Stoves] Stove testing with and beyond the WBT

[Dean Still]

Hi Paul,

3 tests are commonly used for looking at stove performance. Only 1 is the
lab test. The other 2 are field tests and Aprovecho and the stove
manufacturers that I know rely on the CCT and KPT to inform about all the
important things a manufacturer needs to have in the stove, like does it
cook well, what happens in the field, etc. The CCT and KPT have the cook
use her fuel, pot, wood, etc while she makes the normal meals. Then we see
if fuel is saved, if less emissions are made.

The process Aprovecho follows is to learn how fire works and how stoves can
burn cleaner and use less fuel with the WBT and the emissions hood. But the
stove is really designed by the user who knows what is has to do: make
great food. So the field tests are as much a part of the process of
designing a good stove as the lab test. Manufacturers often rely more on
the field tests than lab tests because they want cooks to like their
products.

It's great that the Global Alliance is moving so quickly to have field
testing be recognized as vitally important.

Best,

Dean
