[Stoves] [Gasification] "ecogas" defined

[Kevin Chisholm]

Dear Crispin, Tom, Paul, Ron, and The List

I've been struggling with definitions that are meaningful, sensible, and 
that "will get us where we want to go."

I find that when I look at the "trees" rather than looking at the 
"forest", it is easy to come up with myopic definitions that will lack 
meaning or be confusing when we step back to view the overall context. I 
think many of our contradictory views are perhaps because each of is 
standing a different distance from the trees.

I have taken the liberty of configuring a "Big Picture Approach" with 
teh objective of getting things in perspective.

I think it is important that we be able to distinguish between "Neutral 
CO2" that is derived from biomass, and "Fossil CO2" that is derived from 
fossil fuels. In the attached preliminary draft of a "Energy, Biomass, 
Gas and Nomenclature Flow Sheet" I attempt to lay things out "from start 
to finish". There are probably many opportunities for improved clarity, 
additions, etc.

I would propose that if we first get "the big picture" right, then 
detailed definition of process and nomenclature will flow relatively easy.

Hope this is helpful.

Best wishes,

Kevin
