Keep in mind that a proof of concept isn't that hard to do.  Mr. Bordynuik just has to feed in plastic feedstock during a run, sell the corresponding output and then publicly announce the cost and nature of what went in and the revenues of what came out.  If the numbers are good and he's actually being truthful, he and everyone else win.  If the numbers are good and he's lying, he risks going to jail.

He understands this well.  He announced the Islechem testing...unfortunately all that was said was "mixed multicolored plastic" went in and a "diesel-like" liquid came out.  Not surprising for pyrolyized plastic.  He also hired SAIC and fed them assumptions to use in their analysis, assumptions which were undisclosed and later cautioned about being "incorrect or outdated."  There's never any 'validation' which gives a full, clear picture.

And again, Mr. Bordynuik didn't need to hire SAIC and make them rely on his hypothetical assumptions for their calculations...he just needed to publicly announce the actual cost of the feedstock from a run and the actual corresponding revenues.  He's not that dumb that he can't do that simple math.  By using SAIC, he just leveraged SAIC's name for credibility while continuing to give shareholders incomplete information about 'validation'.
