Excellent idea - carbon neutral (ish) fuel plus regenerated higher
fertility, lower input agriculture plus sequestered stable carbon. Looks
like a win-win-win situation. Anybody see any flies in the ointment?
Does anyone know if algal strains exist that can fix their own nitrogen from
the atmosphere -or would they need nitrogenous fertiliser added??
