I will admit to being not much of a chemist, but what in the world is "HHO"? It isn't "separated", but is "split"?? Huh? I'm getting the impression that it is a mixture of O2 and H2, where electrolysis has been used to separate it. Right? That means that gaseous H2 Comes off one electrode and O2 comes off the other, but it is collected and fed to the engine as a mixture. Right? Yes, that would make the mixture explosive, but I don't see that as a problem as long as the quantity is kept small and there is no ignition source. But calling it HHO? It confused me, but then I'm easily confused :-( If I'm right, the O2 being fed into the engine doesn't do much, as the incoming air is already 20% oxygen. No problem - and no advantage - the creation of pure oxygen is "wasted" in the process.

THE HHO mix is different, the HYDROGEN and OXYGEN is split by electrical means but it is not separated, and a spark could ignite it.
Hydrogen is usually (always?) used as a heat exhanging coolant for large electrical generators, and the media in Stirling engines. It has a very high specific heat (takes a lot of heat to warm a pound of gas) and has low aerodynamic drag. Other gases would cause more drag on the armature and not be as effective at absorbing heat. I remember taking time to fill them with H2. First, we pulled as much vacuum as we could. Then we filled it with nitrogen and measured the O2 concentration. Then we evacuated it again and finally filled it with H2. There was a continuous oxygen monitor that would give us an alarm if there got to be too much. The shaft seals at each end were of the labyrinth type filled with oil. We also had a process that put a vacuum on the oil to get the dissolved H2 out of the oil.
