If he wanted he could build a machine as a fountain outside of his office. The fountain would be lifted above the ground on some transparent (Lexan) standoffs, so that everyone can crawl underneath and see that there are no cables. The fountain would be heating the water, so that it's always hot. The fountain could work 24/7, well guarded so that nobody steals the secret sauce. [But is he going to guard *all* his power plants? That's not realistic. His secret will be out in minutes after the first device is sold.]
But otherwise yes, his short runs of the machine are disconcerting. But I have no dog in this race; it's up to the customer to check what they are buying. If I were them I'd be seriously worried about paying money for a power plant that works on a principle that science doesn't understand. For all I know, it could stop working tomorrow, or it could explode, or it could start radiating death rays, etc. Earlier discoverers of radioactivity were oblivious to the danger, with sad results:
Skłodowska–Curie visited Poland for the last time in the spring of 1934. Only a few months later, on 4 July 1934, Skłodowska-Curie died at the Sancellemoz Sanatorium in Passy, in Haute-Savoie, eastern France, from aplastic anemia contracted from exposure to radiation. The damaging effects of ionizing radiation were not then known, and much of her work had been carried out in a shed, without proper safety measures. She had carried test tubes containing radioactive isotopes in her pocket and stored them in her desk drawer, remarking on the pretty blue-green light that the substances gave off in the dark. [link]
We call that a “patina”.
What is that? A car air filter?
