Worth mentioning is this - the experiment using radiation in the radio wave spectrum to excite an alkali dissolved in water is similar to the device invented by John Kanzius. This invention was initially used to treat cancer but could also split water and ignite the gas in a flame, which was quite impressive.
Unfortunately the device proved to be not gainful, although it was very efficient. It used RF in the megahertz range, which was resonant with sodium. Using microwave irradiation with potassium has the potential to be gainful - to the extent Mills theory is correct, even if the Kanzius device was not. Apparently resonance is involved with KCl too. It would be rather amusing if an amazingly simply way to apply the hydrino theory turns up inadvertently on the internet, which Mills has himself completely missed.
