Well.... uhhhh.....

The general name for the gas mix produced by electrolytically separating water is oxyhydrogen. The process was discovered by William Nicholson in 1800. Lots of inventors since then have claimed efficiency breakthroughs in the separation process. All of those claims have turned out to be false, or based on using various chemical accelerators in the source water.

Oxyhydrogen won't work as a motor fuel the way you expect, because it contracts when it burns. It does not expand, like nearly every other kind of chemical combustion does. The first "Brown" to get involved with oxyhydrogen was Samuel Brown in 1825, who built a vacuum engine.

A modern "combustion" engine is an expansion engine, and works on the principal that gasoline will expand when it burns, and that expansion during the power stroke is used to push the piston DOWN. A vacuum engine works exactly the other way--by drawing the oxyhydrogen into the cylinder with the piston at bottom-dead-center, closing the valves, and then igniting the mixture--and the fuel's contraction pulls the piston upwards.

People who add this stuff to their car and then insist it helps are,,,,
-how can I kindly say?
Probably not using good laboratory procedures when conducting their experiment. If your modern car's engine produces power on the downstroke, what good will adding a contracting fuel do for it? Not a lot, to my thinking.


Oxyhydrogen is a lot more interesting as a welding method than as a motor fuel.
It's not efficient for welding most things, but is very good at a few things that nothing else can do. The separators tend to use a lot of power however--several times as much as a roughly-equivalent MIG or stick welder of the same heating capacity.
