I agree with Mark U that there is plenty evidence für the H2(1/4). They made null runs for all their results and the spectroscopic signals vanished in these null runs and when they did their "hydrino thing" the signal appeared and had the value they expected from theory. I also like the photoluminescence emission spectroscopy result, with which you can measure the internuclear distance of H2 that shows the 1/4 H radius.
But I also agree with Wyttenbach and Simon Brink that the mechanism for hydrino generation might work in another way as Mills thinks. I think they have more of enough evidence for the necessary properties of their catalysts, but the equations and mechanisms could be different in reality from their current form. I think the proper mechanism includes Mills H2(1/4) but could be different. And their are probably mechanisms at play that Wyttenbach describes that Mills ignores or dont know.
But I am confident about their future: the prototype reactors are very good and within the next year they could have a device to study the reaction in detail. They can look into their reaction with the glas reactor and their highspeed camera. In a few months they can do energy in and out calculations to learn about the energy balance of their system and I think they are the only ones with high power reactors in the field. Higher power means, that they learn faster and with more signal/noise about the physical properties of their reaction. The water bath will allow them to run the reaction for a longer period of time. Currently they dissipate heat just through radiation - that hinders them to increase the power output. They have different reactor designs they analyse in parallel and that will speed up progress. I am pretty confident that they will have the most interesting experiment/reactor on this planet within the next two years. A commercial product is nowhere to be seen at the horizont.
