[Gasification] Bagasse uses

[Matthew Pottinger]

Peter, I have to say, you rule. Good suggestion. You're the most
knowledgeable person on this list. I've been lurking, and no, I haven't 
abandoned gasification or renewable energy after these past few years, quite 
the contrary, and I know much more now then I did back then as a newbie. I 
can appreciate your knowledge much more than I did in the past. You are 
quite a genius. Thanks for continuing to bang heads with these people. Have 
you made any real progress with them so far? lol

Peter I know some more things which you might be very interested in about. 
Remember your suggestion on producing methane using steam? I have to say you 
were *almost* on the mark, on the right track so to speak. I'm exploring 
something in that avenue, though I've been told not to speak of it, your 
'unconventional' approaches make a lot more sense than people here will give 
you credit. Don't let them frustrate you OK? You know your stuff.

Yes, I'm baaaaccckkk! :) Remember me? As for those who didn't like me, too 
bad ;)

 and yes I am armed with a lot more knowledge than I had 3 years ago  :) 
I've done my homework since then.
