I don’t know anything about hydrinos, so I’m not qualified to evaluate your link myself. However, the Wikipedia page [1] has nothing good to say about that company. That video makes all my scam alarms go off.
That wikipedia page is rigidly policed by skeptics that pointedly ignore any and all progress especially over the last 10 years. You have to review their progress with an independent mind and evaluate what they have achieved on its merits.
I don’t work in physics, nor do I have a physics degree, therefore I can’t evaluate the theory of their claim. I can’t find any reputable physicists backing the claim that hydrinos exist, in fact they all say that the hydrino state simply isn’t possible. I’d believe in this theory if they actually proved that they’ve generated all this energy or reputable physicists have backed hydrinos. Believing in it otherwise would just be faith.
