Here is a video if you are interested in running an internal combustion
engine on hydrogen. What this person does in the video and what they
fellows have done is very similar.
Hydrogen Fuel Engine Fundamentals Parts #1 thru 10 link:
http://www.youtube.com/watch?v=Jo88bRN8vFwYou have got to get to fact that air is not pure oxygen. So the
oxygen and hydrogen to the engine may be in stochiometric quantities
but the mixture is not. The engine is designed to run on fuel air mix
and therefore some air is gated in.

The experiment needs to be improved as follows;
a) You need a needle value in the fuel line to act as a throttle. You should
couple the throttle to the Hall Effect switch in a way that controls the RPM
of the motor. This will set the 50 Hertz line frequency correctly in the
generator. The Voltage Regulator in the generator are generally resonant
circuits I think so the frequency instability will negatively affect the voltage
stability.
b)You need a hydrogen accumulator and a pressure sensor that controls
how much energy is being gated to the electrolyser. When the pressure
goes down in the accumulator the electrolyser cells should work harder
the bring it back up. For this control you should use a bulk 40VDC supply
rather than a regulated one so that the output voltage follows input.
If the transformer of the power supply doesn't like continuous TRIAC
controls then try using cycle skipping.
c) You need two Variac's variable AC auto-transformers. These are manually
adjusted to split the generators output power between the load and the
electrolyser. The concept is since P=E*I, as you increase the AC voltage
slightly up or down then the power on that path will follow along. Diesel
Electric Locomotives operate this way (sans hydrogen of course) and use
a variable transformer as a Continuously Variable Transmission.
Of course stabilising the feedback loop will do nothing if the electrolyser is not
producing at least somewhat above Faraday hydrogen and oxygen amounts.
It doesn't, by the way, make sense that non-stochiometric quantities of gas
would come from the electrolyser because the feed chemical is water and
if CF Cold Fusion is source of the excess energy, one is never going to see
reaction products because their quantities is so small.
If you have an option get a "Digital" Generator Set as it has a bunch
of features that would make it easier to control the feedback loop.
It essentially works the way the feedback loop should look!
I hope these fellows go on to improve their demonstration because they
started it.
I would rather have self-running proof of overunity energy
with a Carnot perfect gas engine rather than measurements anyhow. So
far what they have looks very good.
