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

[Jeff Davis]

Hi Kevin,

But all gasifier systems (for example WWII car/truck gasifiers) are basicaly 
stoves as a matter of fact they were called stoves. The engine is where the 
gas is burned and the engine is a heat engine. So this is basicaly a large 
T-LUD. Gasifier and the engine is the top burner.
