Zimbabwe Man Comes up Missing after Invention!

I dunno - magic happens in fairy stories and the sciences of physics and chemistry happen in the real world....

You can't reburn water, after the hydrogen and oxygen used to make it, has already been burnt.

AND adding in a very faint mist of water, to the intake of an internal combustion engine, IS a very good thing... it cools the mixture slightly, makes for better combustion, more power etc..

I have all the tables and calculations on day to day drivers and emergency boost settings for supercharged piston engines in WW2 aircraft - so for the reliable daily drive, especially an engine that has to work hard in getting a big load moving, or up a hill etc.. or pulls hard like a freight train engine - especially in a hot dry location - a tiny amount of atomised water from a fogging device IS a very good thing....

But you can't burn burned water...

Water in terms of being the fuel, used to feed a standard piston engine, to provide power from combustion and expansion with air, is the end product or combustion, not the precursor for combustion, so it just does not work.
