Ok. But that still leaves my question. How much energy is used to the amount of energy produced by the welder? And again that still doesn't explain their claim that they are creating HHO which is probably just completely incorrect.
I don't see any evidence that HHO was created and collected. How do they know this was made? Did they do spectroscopy on it? Do they have predicted ab initio type calculations for it's structure and spectral properties? In all honesty, I think HHO may actually be a physcially possible species, but it's likely some type of unstable intermediate species that would rapidly, on the picosecond time scale, rearrange or dissociate into something else. After all, I've been to presentations on the formation of H3. But these types of chemicals aren't something you can accumulate and store. Frankly, the guy is full of BS on his water car project.
