iam having idea about water as a fuel,any 1 help to come up?

Answer 1

Quote:
"There are rumors (and a few "documentaries" on TV) about a car that runs on water (as a fuel). The rumors say that the big oil (and car) companies are suppressing the idea, because it will put them out of business.

The original idea was a well-known scam that a few con-artists have pulled off, over the years. They made cars that actually ran on something other than water. They filled a large gas-tank-like tank with water, and maybe threw in a special pill. And the car drove off, probably running on gasoline or natural gas, from a hidden tank.

The idea gets a small amount of credibility because water can be divided up into hydrogen and oxygen, using electrolysis. Hydrogen can be burned, very nicely, in oxygen, to form water, with no pollution. Of course the water can then be split up into hydrogen and oxygen. Maybe we can even use the burning of the hydrogen to run the generator for the electrolysis. Free energy.

Does that sound suspicious to you? It is perpetual motion, something for nothing. The Second Law of Thermodynamics says "No way José/Josita." This whole idea is a violation of physical laws. Electrolysis of water takes a huge amount of energy, much more than can be generated by burning the hydrogen.

But, go ahead and invest your money in the invention. Or you can throw your money down a toilet. It's about the same.

If it can be used as a fuel, water would seem to offer very cheap energy. There really are ways to use water to help propel a vehicle, steam and nuclear fusion being two of them. You can also use a fizzing chemical like Alka-Seltzer (tm). There are actually people who seriously consider using a fizzing chemical like that. The bottom line is that such an idea is likely to be much more expensive than some form of combustion."

Answer 2

It requires more energy to split the water into hydrogen and oxygen than you get by combusting the hydrogen and marrying this molecule back together again.

You would have more net energy combining two elements that naturally occur in a "ready to marry" state.

Something like a long-chain carbon molecule, and oxygen.

Oh yeah...that's already being done (gasoline, kerosene and diesel fuels).

The fact of the matter is that someday, everyone is going to realize that hydrocarbons ARE the least intrusive of all the fuels. When they are gone, we will naturally progress to the next least intrusive fuel.

The problem is our footprint - too much travel, too much transportation. It has nothing to do with which fuel we burn or use.

Answer 3

I have often thought of combining solar (to split the water) with a hydrogen burning engine. You could use it to power tools, or even a vehicle.

Basically the solar gets you around that pesky 'perpetual motion and conservation of energy' problem.

I've had this thought in my head for at least the last 20 years, but have never had the where-with-all to test it.

Nothing much to do with this, but l've also had thoughts on ceramic cylinder liners for engines.
If I'm right it would provide easy change out, less friction, and better economy. I often thought it would work well with a hydrogen burning engine too.

Answer 4

what's the idea? any hint?!?!
