Chemically speaking HHO makes no sense. It says that the H in the middle is bonding two ways, which isn't possible.
And there's no mention if H2 or H3 (atomic weight 2 or 3) are being used (or possibly created?) in this process.
So what exactly gives here? What am I missing?
Under normal temperature/pressure conditions, gaseous hydrogen and Oxygen are both diatomic. That is, they exist in nature as stable molecules H2 and O2. These "stable" gases can coexist in proportions that would form water without actually doing so. It takes a "spark" of energy to blast at least a few molecules of hydrogen and oxygen out of their diatomic state, whereupon they'd be free to recombine as H2O, and releasing MORE energy than what was required as input in the original spark. This, of course, sets off a chain reaction throughout the mixture until all the hydrogen and oxygen are combined.
As near as I can figure, this Clearwater "genius" must be using some highly insulated, temperature/pressure controlled storage vessel to prevent the mixture from combusting. And may also be using weird temperature/pressure conditions to hold the H and O in their unstable monatomic states.
Pretty nifty engineering, if that's what he's doing.
But I'd prefer viewing any demonstration from at least a mile away.
