Hi Steve
this is not the main unit but the little pipe injector, Now to get H2 from NH3 is easy it is done as part of my waste treatment process, why is it easy because the H2 is 'loosly bonded' as that there is one extra H , Hydrogen will only come away or separate in 'pairs', this is why Hydroxcy is a 'streatched gas' unit, NH3 will loose one H quite easily, if done in proxcimity of more NH3, two of the H will form H2 as a gas and float to the surface, the trick is it has to be done in low oxygen water.
As for the hydroxy then there is another way that you could get it to the ionisation stage, this does involve a magnetic field, and should work, it does on 'air'.
how ever this is a cost in power so I do not know if it will save any thing in the long run.
but providing that the power is all comming from the ICE I supose that it does not matter. it is a simple set up, I will try and draw it up fo you.
