I really don't see the point of this...it takes at least as much energy to "unburn" the CO2 in the air back into organic molecules, as burning the coal/oil released in the first place.
(If it took less, we could make a perpetual motion machine by burning and unburning coal)
Are we really supposed to expend as much energy as we expended in the entire industrial age just to remove the excess CO2 in the atmosphere?
