Salt Water as Fuel
 
Salt Water as Fuel ? I think I will need to hear from joepole on this one. What say you joe ?

I say I don't open videos at work.

Is it about a guy in Florida that makes water burn? If so then I've read about it and it looks to be about as real as cold fusion.

It certainly looks real to me. This guy is awesome. He was looking for a cure for cancer and stumbled onto a potential solution to our energy needs too. This guy is gonna be a very rich man.

Salt water is almost everywhere. Gasoline prices would plummet forever if we started putting salt water in our gas pumps.

If he's burning plain salt water then it's not real.

It may not be easily conceivable, but it's obviously possible under the right conditions.

joe when you get home please take a look at this clip. I am sure you will know and have a very candid way of explaining the reason it is not true. My reaction is if it is so great why have we not seen it in the news ? That is not physics but gut feeling.

It's definitely not possible under any circumstances for salt water to be used as a fuel that produces more energy than it takes in. Sure you can break the H-O bond and burn the hydrogen, but that produces less energy than it takes to break the bond.

Here is some hard data. This source does agree with Joe that more energy is consumed in order to split the molecules than what is yielded. The difference between those two figures is known as "free energy," which this article says can also be harnessed for whatever we need.

It's not a question of getting more energy back than what we've put in, Joe. Gasoline doesn't accomplish this, yet we're still using it. If it can burn, then it can be a fuel used for something. We just need to find the most efficient way to handle it and go with it.

>Gasoline doesn't accomplish this, yet we're still using it.

Yes, it does. It takes less energy to extract, transport, refine, and ignite gasoline than is recovered it produces. If it didn't we wouldn't use it. In fact,w e couldn't use it.

The laws of thermodynamics (specifically the second law) tells us that it did require more energy to make the crude oil in the first place, but that energy was provided by the sun millions of years ago, it doesn't cost us anything to utilize it.

Think of it this way, if you can extract X joules of energy from salt water and it takes 2X joules of energy to extract, where will you get the 2X joules from in the first place?

As joe pointed out, fundamental laws of physics state that energy cannot be created nor distroyed, it can only be transformed from one type into another.

Keep this in mind when you pay your next light bill. You are not paying for energy. You are paying to "borrow" energy, or more specifically to transduce it from one form into another. In a since, it is impossible to "waste energy". Rather you can only transform it into a form that isn't as desirable as the one you are looking for, such as heat emitted from a computer or light bulb.
