So you throw away at least 90% of the power generated as waste heat. You attempt to develop a technology that requires a large graphite dome, heated to above 3000K at which temperature the graphite evaporates, and a PV system closely surrounding this dome which has to operate at hugely elevated temperatures and incident power. You need to control the reaction so the dome doesn't evaporate quickly, and you have to cool the PV cells so they are not completely cooked by the nearby 3000K+ source. Within the dome you have molten silver being pumped around and you need a power source to melt the silver and to start the reaction in the first place. And this is simpler than a technology that was perfected in about 1850?
All this assumes that hydrinos exist and that there is a process that produces energy from transitions to fractional states of hydrogen. But, in reality the theory is riddled with inconsistencies, hydrinos don't exist, and so the engineering issues above are moot. Anyone who invests in this scam after 30 years of utter failure is an idiot.
