[Stoves] CO2 drawdown (Re:Jock)

[Ronal W. Larson]

Nikhil, Jock, list and ccs

	See inserts.  Handled shallowly below because this is a standard topic on the (sister) biochar list.

	[RWL:  You misunderstand Jock (a good e-mail friend , who like me has worked on policy matters in DC).  CO2 drawdown is a responsibility of developed countries - especially the USA.  The cheapest way by far is to pay (fairly) rural inhabitants of developing countries for producing and using biochar..

It does, however, advocate the development and deployment of BECCS -Carbon-Beneficial Biomass Energy plus Carbon Capture and Sequestration: "Any facility that combusts biomass for electricity or converts biomass to fuel and captures resulting CO2 for utilization (e.g., enhanced oil recovery) or storage in underground reservoirs.” 
	[RWL:  Mt perception is that the BECCS technology, despite having received billions, is a lost cause.	The biochar growth rate puts BECCS to shame.  Especially in China.

	[RWL  The odds of that are about the same as the sun coming up tomorrow in the West.

	[RWL:  I remember Eugene Odum, world famous ecologist at the University of Georgia, saying that PV would never pay off its energy debt, because it cost $100/watt  (in mid 70’s).  Now under $1/watt and energy payback time under a year I believe. (wind payback now measured in months.

	To Jock - I agree biochar is only one method of CDR.  Can you name one that looks more promising or necessary?
