Sam's project is not obviously fraudulent. But it also is not what the article was about. All fusion startups except Sam's are obviously fraudulent, as they all depend upon burning tritium that cannot be obtained, among numerous other intractable problems. ITER, likewise. Sam's depends on 3He which is even rarer, but for which they have not obviously unworkable plans to breed in their reactor. Even if those don't work, the reactor could be usable in spacecraft relying on the limited supply, as we do for plutonium in thermoelectric generators sent to the outer solar system..
