I didn’t see where they claimed to have perfected cold fusion. What I read indicated that they had figured out how to use solar energy to break the H2O covalent bonds which seems reasonable.
At the moment this is an absolute record for energy costs with “cold fusion” Low Energy Nuclear Reaction (LENR). It outpaces all research centers, laboratories and universities involved in the hydrogen problem of (LENR) for 20-30 years
In retrospect, it looks like they were talking about someone else; the text isn't all that clear.
Back to the original issue: The Second Law of Thermodynamics says that you will always get less energy from burning hydrogen than it took to separate it from water; in effect, hydrogen becomes a battery. If these people have a way to use solar energy to economically power hydrogen separation, they'd probably be better of just selling the solar power. Sorry, but this whole thing reeks of scam.
Solar energy, or electrical energy is what you would use for a standard process of breaking the bonds, but they are claiming transmutation and their numbers are freaking off the chart in terms of production from a given amount of water.
When questioned about that they just lean on the transmutation and the LENR process.
That’s the problem..
If it’s true, and that is one huge IF. The process, no matter how it transmutes would be huge...
But that’s again the problem.
IMHO
Those would be hydrogen bonds. Using solar energy for splitting of water is not a new idea.
What is new here, however, is the idea of transmuting oxygen into hydrogen. Normally hydrogen is far more apt to go in the other direction, just as we saw it in explosions of hydrogen bombs. You'd need to apply some comparable energy to put the toothpaste back into the tube :-) Our Sun happily survives on simply fusing hydrogen into helium. Imagine the cost of splitting O into many H's :-) Humans can do some of such things, but only to individual atoms, and only on huge particle accelerators.
