[Stoves] Risk of CO poisoning with TLUDs

Hi All;

A scientist would say that the statement "all TLUDs have safe emissions of
CO from residual char" is a hypothesis in need of experimental
falsification.  CO should be measured under a variety of conditions (fuels,
fuel moisture, primary air rates, etc) to see if the hypothesis is false.
If we can't falsify the hypothesis then we conclude that the hypothesis is
"probably" true.  If we do find circumstances where CO emissions are
hazardous, then we say the TLUD is "probably" safe under these conditions,
but not safe under these other conditions.

Scientists are professional skeptics and engineers are professional can-do
optimists, so they differ in their training and approach to research.

Cheers,
Julien
