Do you have links to the history, so that FReepers will be informed?
Does this company have independent testing results?
I have seen this behavior in the civil aeronautics community. There are guys who publish and sell ONLY plans. No one knows who’s built the actual airplane.
And there are guys like Jim Bede who actually printed plans, built the airplane, and went into volume production on the promise that there would be a corresponding power plant, which never came to fruition.

And there are guys like Burt Rutan, who changed the face of the industry, even building an airplane that flew around the world on one tank of gas... but he isn’t a billionaire industrialist, as one would expect.
You can just go to their website and look at their press releases. You may be able to find a stock discussion board for the company, but I think they have been delisted.
