So the question then becomes how do you capture hectares of methane?
Anybody got 10% on this?

Can the coal seam gas technology be re-purposed as the former USSR already
has good, if politically sensitive, gas lines to western Europe. Are these
deposits too shallow to be 'economically feasible'? Unlike humanity's
tenuous future existence that appears to rapidly proving to be economically
unfeasible |-0
