I've been watching this story for many years. I have decades of science and engineering experience, and find the story totally plausible. But it could still take many years more before successful products emerge from the lab. The recurring problem seems to be that the hydrogen-to-hydrino (dark matter) reaction only happens when a very specific set of conditions is set up, and then when the reaction happens it destroys the conditions needed to keep it going. Dr.Mills is going thru the proverbial fifty thousand experiments needed to learn whatever it takes to commercialize his discovery. He has intellectual property barriers in place that effectively dissuade anyone else from investing in parallel research. Plus most people prematurely jump to the conclusion that Mills' work is a scam before they spend enough time to appreciate what he has discovered. It is quite fascinating to know that amazing science is being done in a lab in New Jersey, but 99.9999% of humanity is unaware of it.

Oh, by the way, I don't expect the apparatus will use enough silver to perturb that market much. But if Mills achieves success then electricity will become much cheaper and less centralized. So electric transportation will become more economical. And the market for power semiconductors ought to increase.
