I assume I'm not the first person to bring this up, but I did a search and got no results, so hopefully I'm not beating a completely dead horse here

I just saw a video on yahoo about some guy who put a water-for-gas conversion kit in his chevy truck and doubled his gas mileage. I dunno much about the science of the thing and if it will damage the engine over the long run though.

Anyone have any experience with this, or general knowledge as to whether it's really a good idea or not?

I've heard it's pretty much worthless. The amount of amperage needed to do a useful conversion is beyond what your car's system can provide.

I wouldn't try it.. 4 years of physics in high school and college tells me its a bunch of hooey!

Hard to get past the 1st law of Thermodynamics - In any process, the total energy of the universe remains the same. So you can't get more out of a system than what you put in.

You may be able to increase the efficiency (slightly), but again, you don't get something for nothing.

Don't confuse the water-for-gas with water injection. Different animals - water injection was used on aircraft engines back in WWII - here is a good definition of water injection. http://www.rallycars.com/Cars/WaterInjection.html

The idea is that you are using "spare" energy from your alternator. That is how they generate something from "nothing" in this case. It does make a certain degree of sense. However, the amperage required is to the point that it nullifies the usefulness of the process. I wish I could find the link I had on this a while back. Explains it quite well.

you would also have to tune your car to be able to do it because your MAF thinks that all air coming in is regular air which is mostly nitrogen. if you could add a lot more oxygen from separating the water molecules, the car would lean out because it wouldnt be able to sense the extra oxygen in the intake like using nitrous.

Even if you had a nifty way of efficiently splitting the water with "surplus" alternator power, a gallon jug under the hood is not going to get you much. We need a to have Chemistry major chime in here and state the math, but I suspect you would need to pull around a trailer with a large water tank...

I know there are YouTube videos with many amazing claims, but I don't buy it.

Someone out there will swear that you can put some lead in a microwave and make gold - and others (along with some beer) will try.

if it works out for you, send me a pm.
