[Terrapreta] Catalyst: Carbon Bigfoot

Dear Sean

You raise an excellent point: Char is being used as a carbon neutral 
fuel, rather than for TP.

If GW was not being caused by GHG's, and if char was not being used to 
reduce GHG's, then more char would be available for TP, with all the 
benefits you list below.

If we hang the future of TP on funding from Carbon Credits, TP would be 
dealt a serious blow, if Carbon Credits were not forthcoming.

On the other hand, if we develop TP in a way that it can be successful 
on its own merits for promoting more effective agriculture, then Carbon 
Credits would be a massive windfall, and an enormous boost to TP use.

What do you think we should be doing to maximize the early acceptance 
and widespread use of char for TP?

Best wishes,

Kevin
