Equation 1 · Part 2 · The Domestication of Everything: Biotech's Loop, Closed

Symbol V

log⁡10(P)=−0.563 log⁡10(V)+3.65\log_{10}(P) = -0.563\,\log_{10}(V) + 3.65
VV

What this part means

production volume in metric tons per year — a real economy-of-scale effect, but one that only partially offsets the bioreactor ceiling above it.

Its job in the formula

V is one of the signed contributions combined to compute the quantity on the left.

Where the article explains it

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

…for roughly 51% of total fed-batch cost. Humbird models individual amino-acid prices as falling with production volume along a fitted relationship, log⁡10(P)=−0.563 log⁡10(V)+3.65\log_{10}(P) = -0.563\,\log_{10}(V) + 3.65. 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…
