[Gasification] Getting both heat and char .....

[Doug]

Paul and Colleagues,

Quite awesome and the smelting pot demonstrates how much high 
temperature can be created. Some version of this would I think be 
adequate for Rolf's first proof of concept trial, better than using his 
gasifier. How big have you made one without compromising the key parameters?

Our colleagues are responding to the wake up call, and when a few $$ are 
available,  the ceramic project will be able to draw from the best 
people and technologies in the business. In the mean time, we can all 
contribute to assembling Rolf's projects needs, and I hope others will 
join in and help make it happen.

Doug.
