Less amps = less heat = less HHO. Hey Makg, what if we ran a line from the exhaust to the "HHO" to produce more heat\gas fume mixture? Would that change much of anything? Just asking, not building or going back to HHO is going to change the world for the better, just thinking outside the box I guess.
In principle, heat electrolysis ought to work. This is observed in O and B stars (big friggin hot massive stars, easily seen even in fairly distant galaxies). It almost certainly happens during supernovae or other nuclear blasts.
But the kinds of temperatures you need make it happen will bathe the truck in hard X-rays. The surface of the sun isn't hot enough (it's only a G star), though the interior is. And thermal radiation is
extremely inefficient; you'll need a small commercial power plant to do it.
You could make a heat generator to do that (say, a Stirling engine), but you're still not going to get out what you put in. All that heat comes from gasoline. Basically, you're trying to power a house with a potato battery. Yes, it works, but not on anywhere near the scale you need.
It's not heat that makes electrolysis work. It's electromagnetic forces. If you boil water, it doesn't electrolyze. Electrolysis works by jiggling electrons (that's what electric current is) enough to make them jump from oxygen to hydrogen, which releases the chemical bond between them. It's distinctly
nonthermal.
