[Gasification] Methane

[Dick Glick]

Hello Peter --

I tried to do something in Belize -- working with an American then living 
there -- got stuck when:

"It has become quite clear that the Mennonites simply want to bleed us for 
the information and proceed on their own. I have learned that this is 
typical of them."

Whatever -- although conceptually -- methanogenic anaerobic fermentation --  
is simple -- care must be continually exercised to insure that the process 
can be maintained to be continuous.  This, particularly, when the system is 
designed to fit into the society and environment to minimize capital costs.

And then the soil amendment needs tailoring to local crops or so as to 
maximize quality -- including sale to Europe or Japan or whomever -- as a 
high quality organic fertilizer.

Anyway, CO2 is liquid at room temperature at 6 atm.

We also tried to do something in St. Kitts -- this time my naiveté didn't 
realize that my 'big-time' partner was only interested in maximizing his 
return on my technology -- so we parted ways -- I'm idealistic, but not that 
naive.  What was mentioned was that the price for human grade CO2 was 
something like $2500/ton (I never verified this, but there wasn't much of 
CO2 in their beer!)

What a history -- few successes and many failures -- but the technology as 
we've approached it -- time has come or we're close.

Best, Dick
