[Stoves] Very small stoves and reheating food

[Paul Anderson]

Richard,

It is the words "feed ... continuously" fuel that is a problem. The 
pellet stoves (heaters) are acceptable and successful because the 
continuous feeding of fuel is automated.   No such luxury with 
inexpensive stoves for economically poor people.
