[Stoves] Fwd: Smoke-free biomass pellet fueled stove

Tue Nov 6 10:06:46 CST 2012

Hi All,

The cost of stoves rises when designers and manufacturers are asked to
produce stoves that are cleaner and last longer. Luckily, the understanding
of both materials and how stoves can be cleaner has and is expanding
exponentially. So now we are in a much better position to make cleaner
longer lasting stoves that can be sold at market prices. I bet we'll see a
lot more this year at ETHOS and the Global Alliance Forum.

Stoves tended to go up in price responding to the demand for cleaner
combustion and better durability when it was thought that carbon credits
would pay some of the bill. But now as the carbon credit market shrinks
purely market viable stoves are in demand and are available. For example,
look at the Peko Pe, the Champion, etc.

Best,

Dean
