I once shared a building with an inventor of biological things. One of
his schemes was to turn chicken waste back into chicken feed..
Supposedly, it worked but it sounded too much like perpetual motion to
me.
The final straw in our relationship was when he convinced unemployed
shrimpers to harvest cannonball jellyfish and he took them back to our
shared lab where he treated them with lye in a big vat. This yielded
large amounts of nearly pure collagen for medicinal purposes. It also
made the building smell like a rancid chinese restaurant. I'd have to
call my employees and givem them a "Stench factor" on a scale of 1-10
so they could decide to come to work or not.
