[Gasification] Where is Everyone?

[Bob Stuart]

Thanks, Doug.

I'd been worried about coking, so you have saved me a test setback.  
Will a cyclonic separator upstream help?  I've never dealt with coking, 
so I don't even understand its vulnerabilities.  Would a good wire 
brushing with each new load of fuel do the trick?  That could be 
automated pretty easily.

All the ICEs have to deal with the power for a compression stroke.  I'll 
do the math on intake vs exhaust volume before building, of course, to 
make sure the turbo efficiency is a minor fraction of the equations.  
With a built-in air pump, a condensing flue is easy to arrange, and it 
recaptures any heat used to burn wet wood.  Would the steam help clean 
coke?  It eats carbon in an ICE.

 From what I know about generators, a rapidly spinning magnet is quite 
effective.  Those little DC-DC voltage converters are surprisingly small 
and efficient, running at very high frequencies.
