There are a few problems, beyond the one in the other comments that come to mind. (1) How are you assured to keep the proteins in the machine? (2) could this lead to a prion infection? My understanding of prions is limited so take this thought with a grain of salt. I was under the impression that while there may not be anything different with the composition of a prion pathogen, they tend to be misfolded and that misfolding tends to be contagious to other properly folded proteins.

I wonder if there isnt something that eats prions too. After all, if prions were impossible to destroy, then the whole planet would be one big pile of prions.

Didnt the planet have a LOT of coal since for millions of years there were no fungi to digest the dead trees?
