where P is price in dollars per kilogram and V is production volume in metric tons per year — a real economy-of-scale effect, but one that only partially offsets the bioreactor ceiling above it.
The passage around this formula
where P is price in dollars per kilogram and V is production volume in metric tons per year — a real economy-of-scale effect, but one that only partially offsets the bioreactor ceiling above it. His own summary conclusion is that “metabolic efficiency enhancements and the development of low-cost media from plant hydrolysates are both necessary but insufficient conditions for displacement of conventional meat by cultured meat” [ 13 ] — necessary and insufficient, not impossible, which is a materially different claim than the industry sometimes attributes to him in rebuttal.
