Running a V8 on Hydrogen?

(1/4) > >>

Jonny Boaterboy:
Well I have just been reading about installing a hydrogen system on my V8 to increase the MPG. At first glance it seems like a good Idea. you attach some bottles to your engine bay with water and baking soda in them, pass a current through it and it gives hydrogen..... stick a tube on top of the bottle and put the tube on the air intake and there you have it hydrogen going into the engine thus increasing the "Bang" in the engine and therefor less pedal pressure tho get you going...... and more MPG

Has any one heard of this? more to the point is anyone running on hydrogen? they claim it cleans your engine and makes it run smoother... does it? or will it wreak your engine?

Here is a link to one of the people selling the system:

sounds like a good Idea what do you think?

The amount of energy you need to electrolyse the water into hydrogen will be more than the amount of energy you get out of it by burning it.  That's the mahoosive flaw in most of these magic water schemes.

I'm not sure what difference the baking soda would make, but I'd have thought you'd have needed a lot of soda to yield much difference in your hydrogen electrolysis when you're talking V8 quantities of hydrogen.

That said, a small amount of hydrogen could conceivably tweak the efficiency of your engine a little by making it burn the dino juice more efficiently.

I'm not really sold on the idea though.

can I just say if its an aliminum enging DO NOT use it as over heats engine (this is from a m8 in the no)

The soda is needed to make the water conduct ; it'll only electrolyse if you pass current through it and you can't pass much current through pure or tap water.  Proponents of 'free gas from water' are pretty coy about the costs of this necessary additive (although it must be cheap, surely) and the cost of replacing the stainless electrodes which corrode (maybe not so cheap).

Like you say, these gizmos are only intended to trickle a small additive amount of hydrogen/oxygen mix to the engine.  On straightforward laws of thermodynamics, you can't get more energy out of burning the H/O mix than you put in with electricity from the alternator.  There remains a theoretical possibility that the presence of H/O mix somehow magically improves the thermal efficiency of the normal petrol burn more than the (at least) 50% losses involved in generating the electric, but frankly I don't believe that all  :)

No, I haven't tried it.  Nor have I tried a wind generator on top of an electric car so it fuels itself for free ...

cheers, Ross K

Well when you get it working let me know as the cost of LPG isn't all that cheap anymore.................... :'(
