Most plants use so-called C3 carbon fixation, which uses a fairly basic Calvin cycle. This has an overall efficiency of at most 3.5% (relative to Sun radiation energy input), whereas the less common C4 carbon fixation cycle peaks at over 4%. C4 and CAM (crassulacean acid metabolism) are a form of convergent evolution, where both use phosphoenolpyruvate (PEP) to capture CO2 and thus create an increased concentration of CO2 around the RuBiscCO enzymes to reduce photorespiration.


Much longer article... But, they ignore some key points, trying to focus entirely on rapid growth. It's not how efficient the plant uses energy from the sun. It still has to take in water, CO2, and nutrients from the soil, to act on. Moving stuff from roots to leaves is slow. The greatly downplay the presence of abundant CO2, is what makes the magic happen. The goal is to reduce CO2, but these Frankenplants and trees are going to need more than available in the wild, just to survive.

Isn't Bessler more of an orbit?


Studies show that if you force several tubs of peanut butter down the throats of newborns, in some cases it could potentially be toxic. In cities where infant-PB-stuffing is more common, infant deaths increased by over 47% with corresponding increases in dead-infant obesity.. -IBdaMann

In a sense.
