Here’s more info on it and vids too. Notice it is not a normal flame. THere is something going on here besides ordinary combustion of hydrogen.
Yes, it’s certainly not a pure hydrogen flame. Trying to stick to the concept, you might suppose the yellow is due to sodium flame spectrum, but how would the sodium be expelled?
In the Youtube video I watched, his patter did not involve electrolysis. He said something about “heating”. In that demo, he stuck a paper towel in the tube, then later withdrew it to show it wasn’t necessary. Hmmm. In another of the videos he put a fluorescent tube in the RF field to show how it glowed.
I wonder if the “flame” is an analogous discharge phenomenon. Something funny is going on! I feel certain electrolysis of H2O is not the principal effect, if it’s involved at all.
