[Stoves] Understanding "charcoal making" stoves. Was: energy lost in charcoal making and briquetting

[Kevin Chisholm]

Attention Tom Miles and AJH:

There seems to be a difference in opinion as to what constitutes a stove. If 
Jeff and I have a different understanding of what stoves are, there is a 
good chance other List Members may be unclear also.

Given that this is the "Stoves List", we should all be on the same 
wavelength.

As List Moderators, could you please provide what you feel is a good 
definition of a "stove?"

Thanks.

Kevin
