I'd suggest that instead they spend $200K on independent research to check, test, and improve the SRI instrumentation and calorimetry assumptions.
The problem is that the SRI reports are already independent research, and are being ignored/dismissed by people for dogmatic reasons rather than technical questions. There is really no certainty for Brillouin that another report by another independent research institute would convince people that what they have is real. Which is why they are going for proof through commercialization.
I made my own investment mostly on the basis of such reports, and of confirmation by non-LENR people that Tanzella was neither dishonest nor incompetent as the main issue that is often raised is that Tanzella is biased because of his own research in LENR.
If you are really interested in the question, getting in touch with Tanzella is not that hard and could probably be arranged.
Don't worry, they won't. It's the last thing Godes would like else he would have arranged for it long before now-- remember that the claimed results 4 years ago are essentially the same as now. And I suspect they will be same 4 years from now, still unverified. BLP is the model for Brillouin.
You have made a lot of references to the fact that the results are the same as the results four years ago, and I feel they have not been properly adressed. You are indeed right that Brillouin claims that they reached 4X in 2015 but an impressive section of the investment documentation is dedicated to explaining how this result was achieved and why it could not be replicated (I am not sure all this has been told by Brillouin in public communication so I won't say more). Of course you might say that they are scammers and that those explanations are lies, but their willingness to be transparent about those results and their inability to build on them is part of the transparency that distinguishes Brillouin from other LENR companies.
This 4X result also explains part of the overly optimistic predictions of 2015.
