There are a couple of threads about CGON on here.
I have been contemplating it for the 90 - not for fuel consumption.

Did he just invent this, or is the news paper a bit slow on the uptake? You have been able to buy kits from the states for years. I was toying with the idea of getting one over ten years ago.

People have been doing it with jam jars inside the bonnet for years.

people have also do this with water before now. Thought Volvo got into trouble with one of their race cars for it.

So why if its 'been around' is it not being used by the big car companies ?

OK I am almost 50 years out of university but this still smells like snake oil to me. To split hydrogen from oxygen in an electrolyte takes at least as much energy as is released again by burning the hydrogen in an engine. It may well take more energy , wasted in things like heating the electrolyte and resistance heating of the wiring in the cells etc. And that energy is produced by the car engine, so at best its a zero sum game.
Car engine produces energy - some used to drive alternator - some alternator output used to power "fuel cell" - gasese generated back into engine - gases burned to generate less energy than used in fuel cell.
IMO the likelyhood is that the power going to the rear wheels will be a bit less than normal but the mix of gases being burned means that there is a bit less CO2.
Can anyone whose physics and chemistry is a bit more up to date comment on this? I might be wrong but it looks to me like the "cold fusion" claims we periodically see.
P.S. The ratio of ortho hydrogen to para hydrogen is a max of 3:1 at room temperature and above. But AFAIK there is no difference in energy released on combustion anyway

But AFAIK there is no difference in energy released on combustion anyway I don't disagree with what you are saying, and AFAIK the main claims for this device are about cleaning up emissions rather than decreasing fuel consumption which is only around 5% I think. I think the theory is that this would come from the hydrogen enabling more complete combustion of the primary fuel. I don't think anyone is claiming over-unity power production on this.

Can anyone remember the 'steam injection' which was around in the sixties and seventies?
It was a simple water reservoir which was heated through the exhaust manifold, and the steam was fed into the air filter.
Smoother running and better MPG were the claims.

My son has a Water Methanol injection fitted to his Focus ST. This cools the charge significantly and increases power.
But does it clean up the emissions?
Probably: the car has no cat yet passed the MOT tailpipe emissions test.
I do wonder if a small Hydrogen cylinder might achieve exactly the same result.
