HHO Dry Cell Hydrogen Generator System
Discussion
One of the guys in the office mentioned these to me earlier, and we both agreed it had all the classic signs of snake oil.
However, is there any fact behind the theory..?

Perpetual motion you say?
Marvellous!
ETA: Maybe I should explain a bit more...
Engine turns alternator, alternator generates electricity, demand for electricity increases to power electrolysis, resistance of circuit increases, engine load increases to power electrolysis and more fuel is required.
As energy cannot be created or destroyed the extra fuel required as to power the electrolysis results in more energy required than released from the process.
Doesn't work for the same reason you can't stick a wind turbine on your roof to help power an electric car.

You joke, but I spent 20 minutes on our stand at a well known outdoor car festival earlier in the year explaining to someone why this wouldn't work, and after several attempts along the lines of:Me - 'Yes sir, but you would use more electricity driving the turbines through the air than you would create from them'
Punter - 'Yes, so it would create electricity as it drives through the air'
Me - 'Yes, but it would use more than it creates in that proces'
Punter - 'But it would still create electricity, so how does that matter?'
etc.
The worst thing was at the end of the very long 20 minutes when he begrudgingly accepted it, I'm still not convinced he actually believed me. The second worst thing was that it wasn't the most stupid idea that I had proposed to me in that day, let alone the week I was on the stand. I was left wondering what people think engineers actually do for a living.
I should add that this was a well dressed, well spoken individual, clearly a functioning member of society, and that I'm 99.9% sure it wasn't a wind up (no pun intended by the ambiguous spelling).

Yep. The UK, birthplace of Charles Darwin and Stephen Hawking is 16th in world for education in Science.Quite frankly I think 16th is an over estimation.
here is one on a car..

^^ They didn't?
This is an old one. As it is, it's complete snake oil, which you knew already. If you could control the alternator so it only draws load during over-run, use some of the energy to electrolyse water, and store the produced gas so it's only dumped into the engine during acceleration... then you have a hybrid car, with the only difference to other hybrids being how you're recovering and storing energy. But it would be a crap hybrid, as
a)electrolysing water is pretty inefficient, so you wouldn't get much energy back
b)if you did get significant amounts of gas, controlling it all would become very difficult for the ECU - the engine would knock, stutter, surge - you name it.
Best stick with battery or flywheel based hybrids then.
