CO2 is produced by the power plant, not the air conditioning unit. So every power plant would have to have some sort of “carbon-capture” equipment that is powered by renewable energy. Not sure how that would work, but would probably raise the price of electricity astronomically.
I think the intent is to remove ambient co2 from the air as it is pushed through the condenser coil. They still are idiots, but at least that concept could work, as long as the co2 made powering the a scrubber is less than the co2 adsorbed. Still begs the question of whether or not co2 is an issue or a blessing. Science they say... Myarse.
