the CO2 exhaust isn't really carbon neutral is it?
It's using 'current carbon' which is basically the same thing. Plants grow using CO2 in the air, we burn the plants and that CO2 is released again. If we just left the biomass to rot on the ground it'd produce CO2 and / or Methane depending on the type of decomposition it underwent. Verses plants and animals lived millennia ago, died, got compressed by huge geological forces and finally we come along and extract it a…
but we still need to manufacture ammonia etc for fertilizer to grow the next year's plants...
