That study is so inadequate that it is laughable. Besides I have seen it already and evaluated it in detail. I suggest you do the same.
HINT #1: University of Notre Dame is in the USA as are all other researchers and research expenses involved with KBLB.
HINT #2: Where is the USA Mulberry leave source? That study assumes they are free trees and the only cost is cutting the leaves. It also clearly mentions the need to grow those trees as a front-end activity. What happens to the cost per ton of Mulberry leaves for every 500 miles you ship them?
Hence, KBLB has no significant inventory (not a metric-Ton or even close, and certainly not 50 or more as some seem to believe).
