Could salt water fuel cars?

Posted October 08, 2007 10:47 AM

From HowStuffWorks: Daily Stuff Feed:

There may be water, water everywhere and not a drop to drink -- but what if you could substitute ocean water for gasoline? It's a little like alchemy, but it just might work. In the future, you might see a lot of confused seagulls hovering around your local gas station. That's because rather than gasoline, gas stations could smell a lot like the beach. It depends on whether the kinks can be worked out in an invention created by a 63-year-old named John Kanzius that could create an alternative fuel out of salt water. Through sheer serendipity, Kanzius, a former broadcast engineer, found out something incredible -- under the right conditions, salt water can burn at incredible temperatures. With a little bit of tinkering, it might even serve as an alternative fuel for our cars in the future.

...No, wait. Page 2 of the site.......

"Both struggle with the energy input to energy output ratio -- or efficiency. This huge stumbling block causes some to view inventions like Aquygen and the RFG as useless science. While the RFG produces a hydrogen flame that burns stably, the amount of energy it puts out is less than the amount of energy needed to power the RFG. In this sense, any energy that comes out of the salt-water flame cannot be considered a source of power. It's just a manifestation of the energy being put into it, only in a lesser amount."

Nice impartial reporting. Just giving the facts and science. Hooray for proper reporting (I was getting a bit worried as I read the first page).

Now, if we can find a use for separating hydrogen from water using radio waves .......Oh, I just came up with one........and it's weapon-based . I think I will keep that one to myself.

I was thinking of perhaps a new form of desalinisation process to extract hydrogen and oxygen from salt and then recombine them in a more energy and resource efficient way than current methods.

Your suggestion is intriging. By what process do you see this happening?

Ahh, something along the lines of separation of the gas H and O from the water leaving behind all the other contaminants (sodium, polution, etc) and then recombining H and O to get water. Sounds a bit silly but if it could be done more efficiently than current methods then it could be a potential winner (filtering salt water is not easy and desalination plants are rather large and expensive places to build and maintain). Just an idea, but when a new idea comes along (yes it has been proven to work, even thou the primary proposed use is a load of rubbish) it is a good idea to see if it can be used for other purposes rather than just ignoring it out of hand.

No other ideas spring to mind (except my original).

Yes, others have already suggested this approach: electrolyze salt water to produce H2 and O2 gases. This of course consumes electrical energy. But we can recover part of that energy investment by feeding the H2 and O2 into a fuel cell to produce electricity and ultra-pure water.

I changed to a new avatar because a few people reacted very negatively (in private communications) to the previous one, as if my admiration for western and Israeli soldiers makes me an imperialist warmonger. I consider pacifism to be a huge mistake, but on the other hand I only support war when absolutely necessary for self-defense. I have very mixed feelings about the Iraq war, but I won't get dragged into a debate about that, especially not in an engineering forum. Anyway, now my avatar won't give anyone an excuse to assume anything about my politics.

Well now I am gonna assume that you like making bombs out of snakes.

I had not noticed this before you pointed it out, but I can see how my new avatar might resemble a bomb. This resemblance is completely unintended -- it is actually an ancient symbol from alchemy (I am a chemist).

Ah, very cool. I didn't mean anything negative in that so please don't be offended.

No no no not electrolyzing, it's too inefficient, I was thinking of a different possible approach.

Out-of-the box thinking and all that.

Regarding the production of pure water from salt water, it's going to be very difficult to develop an approach that is more economical than reverse osmosis. I would suggest industrial-scale solar stills as an alternative. Or if you want something a little more "out-of-the-box", how about freezing salt water to produce relatively pure water-ice, using this ice for centralized cooling systems, and collecting the runoff. But this would probably be far too expensive.

Gosh, on the second page there was an inference about that annoying little law that keeps getting in the way. The Law of Conservation of Energy.

Josh Clark - the author of the article - did his homework and didn't jump like Mike O'Mara to give to Kanzius unconditional credit.

About three weeks ago, John Kanzius was featured on Discovery Channel (Daily Planet) in Canada. This time he seemed to be more cautious in defining salt water as the future fuel for cars. Instead, he came up with another miracle: crops are growing better if watered with RFG-treated water....

This guy never stops!

He said that, that's even worse! DANGER, DANGER WILL ROBINSON! <hooks flailing wildly>.

OK- He never stops. What is he getting out of all this nonsense?

What he gets? MONEYS for more "research". He's a master in TV shows as he was the manager and/or owner of a TV station. He is building a false credit by making waves in the media. How many decent and real inventors had this opportunity?
