[Stoves] Charcoal Champion Stove. Was: Charcoal Rocket Stove

[Thomas Reed]

Dear Paul and All:

I am currently reading the biography of Benjamin Franklin Walter 
Isaacson.  Franklin was arguably the most creative American to date.  
Not only did he invent the lightning rod and Franklin Stove, but the 
library, the fire department and hospitals.  He appeared to be very 
modest, but this was simulated in order to be better able to communicate 
with his fellow man which he did very effectively. 

We here at STOVES are the leaders to a new age in which "cheap oil" no 
longer dominates the fuel market and we have to re-examine our energy 
and fuel options.
We all are mining the same fundamental truths, so I suggest we should 
all be modest (or simulate modesty) in our talk, actions and inventions. 

Paul Anderson has done an excellent job (below) and I can hardly wait to 
catch up with his latest inventions.  Benjamin Franklin made many 
inventions, but said that he had benefited greatly from other 
inventions, so refused to patent his. 

Unfortunately, I live in Denver and Paul lives in Normal, Ill, so we 
meet seldom but with great enthusiasm.  I tend to work more on the 
fundamental chemistry of fuels, while Paul is combining 
combustion/gasification knowledge to make ever better stoves. 

Onward to a (better/worse/no/healthier) future
