Hydrogen power
Iv just been reading in the May Car Mechanics and there is a good writeup about part hydrogen fueling.
The Kit costs £500 and im certainly considering saving up for it

I am not convinced, read that article the other day.
You cant get energy for nothing, and it must be less than 100% efficient. Therefore as its pulling the power from the alternator you will be using
more fuel.
These things have been discussed no end of times on here before.

no no no no no no...
it takes a LOT of energy to break oxygen and hydrogen, way more than a car electric system can produce i think.

the only reason it will save fuel is by helping to burn petrol more cleanly and efficiently by spreading the burn better.
my advice, stay well away.

Sounds kind of pointless to me! Like flak monkey says, you don't get out for nout, thats my main beef with electric cars, where do they think
this free electricity will come from? The environmental damage will still happen, just at a powerplant instead of an exhaust!

nonsense = have you not heard of the flux capacitor????
the answer is here.
Dyno Test Results and Official MOT Emmissions Data will be published here soon.
date on page is 2008, we are halfway through 2009.
says it all.

i agree with the conservation of energy aspect of it, but some people argue that these systems work by improving the efficiency of the IC engine by
adding hydrogen to the fuel (non seem to provide a mechanism by which it works though). IIRC car engines are only 25%ish efficient, so there certainly
is room for improvement!
I think the main benefit of electric cars is that the energy could be produced in a nuclear power plant, which doesnt consume hydrocarbon reserves.

i do wonder though, if you sprayed water in, is the engery released in the fuel burning enough to split hydrogen and oxygen?
i've heard of forest fires being put out by planes full of water, but instead the heat splits the elements and causes an explosion
similar to this, but more convincing

Thats just the same effect as putting water on a chip pan fire. Wax is essentially oil, so when its alight and molten it will float on water....

Wow, I'm really convinced. But I'm going to use all that "Spare electrical energy" to run an electrical motor, like KERS....
but better. 
With the left over spare energy that my car produces, I'm going to feed it back into the engine, thus creating a perpetual motion machine......
I don't know why no one else has done this.

My thoughts on this is that it cant work , but maybe it does help efficency in the same way as adding propane to the inlet air of a diesel engine
helps it burn more efficently.

The only way to split water into it's component parts is AFAIK Electrolysis, heating it up just turns it to steam.
However cars can run water injection to gain a power boost (IIRC due to increasing the effective density of the charge air and therefore it's
expansion once heated by the fuel).
If disfunction is a function, then I must be some kind of genius.

ive looked into this. a car alternator does not output enough power to efficiently produce enough hydrogen to make any difference. but ive spoken to
several people with different kits based around this theory claiming massive differences in the car. but from what i can see its placebo effect

yeah, as soon as you look for improved mpg you drive smoother.
