I had a guy come into my shop with a 2005 Expedition with a hydrogen system - supposedly it was a 2 mpg improvement in town and a 4-5 on the highway. Not sure how much I believe it - the system was certainly a cluster $%$# under the hood - hoses and crap everywhere. The intake had several hoses going into it - none of it looked very professional so not sure if it was a new system or this was how it was supposed to look/install.... he wouldn't answer any detailed questions about it.

The only "gains" from these systems is from the engine running lean which does give you a little better mpg but probably isn't very good for them.
If these thing worked, how come no Univertisy or engineering school has proven that they do? How come NO car manufacturer is using them?
How could anybody forget this thread, I really hate to drag it back up, but it exposed the complete and utter failure to prove anything, also Myth Busters did a piece on it too...."BUSTED".
Ok, so what says you, former ford engineer? What says your engineer peers? What says Ford?
I'm not trying to be sarcastic. I am really wondering what you or people you know think about it.
I read an article recently on combining H with CNG but that was commercially combined fuel at a govt test pump.... They did show Reduced emissions and increased power and MPG as H has about twice the BTU output of CNG... same effect was also found with CNG-diesel hybrids
the problem with the onboard HHO systems is that the load on the engine to produce the Hydrogen will offset any gains... its the whole perpetual motion thing
I am glad to see folks trying to create an alternate fuel approach though... thats how great discoveries occur....
SDD.... I love that Mythbusters show too... Gawd some people have the greatest jobs

I don't know what Ford says. I haven't been there in almost three years.
I say that it can't possibly gain you ANYTHING. It takes more energy to split the hydrogen and oxygen than you can get back by running them into the engine. Anyone that had a science class in school should be able to understand that this is perpetual motion. You want to put a little energy into creating two gasses out of water and then gain a lot of energy by combining them. It's impossible. All the engineers that I know agree with that.
Some people have claimed that the electricity to run it is free because the alternator is going to produce the electricity whether if it will be used or not. That's false. The alternator only produces the current needed to keep the voltage were it belongs. If there is more load the alternator puts out more current to keep the voltage up. So when you add the load of the HHO generator the alternator works harder and it takes more work by the engine to turn it, so the engine burns more fuel to work harder. You can't get something for nothing.

I think they would make better discoveries if they worked on things that are possible, not pie in the sky impossible things such as HHO. Perpetual motion does not work.
you have to get the energy to breakdown the Hydrogen from somewhere. but getting the energy from the same source you are trying to drive with that hydrogen energy is not possible for the reason i mentioned above.... however solar, wind or regenerative energy from braking may all be possibilities in the future...
