Power plants could greatly reduce their CO2 tax by bubbling their output gasses through water, which takes out much of the CO2 and creates carbonated water.
The carbonated water could then be piped to living green plants, where it can be proven that the plants thrive and grow faster, and with better drought resistance due to the CO2 absorption through their roots.
EFFECTS OF CARBON DIOXIDE ENRICHED IRRIGATION ON YIELD...
Water demand varies inversely with CO2 concentration in soil.
