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.
