David- I'm still confused about this. With Danny Day's pyrolysis, 
biochar remains a semi-precious commodity. I have yet to understand 
what the limiting factor is...time? I don't know, but from what 
practical material I've seen offered, I have to assume that pyrolysis 
is not a very, shall we say, municipal technology currently.

What say?
