Motors Cars Running on Water...

Isn't that the kit that the Mythbusters guys comprehensively showed was crap?

I think the point is made by the article:

Wheras (I guess, and hence the reason for the system) HOD does away with those losses.

 

Interesting. I'd overlooked that paragraph, thanks for pointing it out.

And, electric cars aren't boring to drive. They've got a ton of zero-rev torque, and are have a much greater power/weight ratio than a conventional IC engine. The thing that's holding them back is battery capacity and power output (not to mention weight), and hydrogen fuel cells promise to make that simply not an issue.

 

It produces Boron Oxide?
Just did a quick calculation, there is no Boron Oxide. Boron Trioxide is the closest thing available (B₂O₃.

EDIT: My mistake, Boron Trioxide can also be known as boron oxide (I'm a moron).
A quick look on Wikipedia shows that it's a solid (and may be hazadous).

Personally, this water car seems like a load of tripe to me.

 

I have not seen that episode of mythbusters. I have no first hand experince with the kit so I cant say. All I reported was what I had found and have found in searching for other fuel sources.

I am completely in love with IC engines so electrical cars turn me off, I love the sound a large engines makes when accelerating hard.

I see no replacement fuel in the near future and hydrogen is a joke in any form being used. Honestly I say each country should grow its own fuel. For gasoline engines increase compression ratios and run alcohol. For diesels make simple oil and let each country suply itself.

Hey,

Are you talking running on water or hydrogen? If you want to run on water, you can add a water injection kit. This will send a spray of water into your cylinder along with gasoline(petrol) (still need it to burn). When the gas(petrol) ignites, the water boils and vaporizes (the water vapors take up something like 3000 times the size of liquid water), plus it absorbs some of the heat from the fuel burning to keep your engine cooler. Then you *could* lean out the air fuel mixture.

Other end of it, if you’re talking about running on hydrogen, there are a couple of issues. First, the hydrogen tends to get mixed into the metal of most engines, causing brittleness. Second, (as previously stated) hydrogen doesn’t have the energy density of fuels being used in cars today. Third, if you’re going to use any thing other than water to create your hydrogen, you are giving no overall benefit to the environment (solar cells/hydroelectric/wind power + water = coolness...).

In addition to the boron process, there is another one out there that uses aluminum and lye (and water). The lye acts as a catalyst and strips the oxygen from the water and binds it to the aluminum (saw a set of plans for that that can fit into your engine compartment. Just have to find them again. (Dang late night web browsing sessions...)). Down side, is water is used up, and you'll end up with a bunch of aluminum oxide. *shrug* I guess everything has a trade off...

 

You dont know much about cars fo you?? by adding water you cool down the intake air meaning you can get more air into your engine. it has the side effect of cooling down the expostion in the combustions camber and reduceing how much the combustion gasses expand by.
Also iam no chemist so if anyone else more knowlegeable than me wants to correct me but i dont belive hydrogen can react with the typical metals found in an engine.
3rdly the catalyist you describe anit a catalysis because it gets used up the in the reaction ie becomes AUoxide catlyist just provide a surface for things to react on
And last but not least when you expose a peice of aluminum to oxygen only its outer layer forms oxides forming a hard layer that stops anymore oxideation so that would stop your so called catalsist from working as soon as it made
I could go on but ill leave that up others

 

I guess you're right I don't know a thing about cars.

I guess you're right that water injection cools the combustion chamber making it possible for you to lean out your mix (this causes more air to be in your cylinder, that means more air than gas.)

Oh and I stand corrected. The steam produced by the water vaporizing is 1600 times larger than the liquid form.

I'm sure that you're right about hydrogen not being able to mix with the metals in an engine.

Since you were right about the previous statements, I guess you're probably right about the rest of them.

Sorry for wasting your time with my lack of knowledge about anything.

P.S. I found the website for the hydrogen generator again. It uses lye(Sodium Hydroxide) as a catalyst and the aluminum and water as reactants. It's located here: http://h2gen.info/genplans.html

 

Even if iam wrong on all the other points it take a hell of lot of energy to convert aluimum oxide to aluiminum which would preberly make your way of producting hydrogen more damgeing to the enviroment than petrol would thus geting rid of the hole point of useing a hydrogen powered car.

And unless you knw how much the combution gases expand by noramlly you cant say whever steam will make that much off a diffrence.

 

I think in about 70 years cars will all be running on Fusion Reactors.

 

Never said that using the method I mentioned was environmentally friendly. In fact...

I totally agree that it's not a fool proof concept. However neither is using Boron. I was just offering another alternative.

And as for the water injection, something that increases it's size by 1600 times, absorbes some of the heat out of the cylinder, cleans away carbon deposits, raises the apparant octane of your fuel and increases the combustion chamber pressure with out adding any more fuel or air... Well, it might make a little difference...

Here's a couple of sites on that.

P.S. I'd love to try running on fusion...

 

Even more fun to try running on fission.

 

but there have been many people who have had there car running on water with just electrolysis. Stan Meyer was one of them people he had a dune buggy runing on just water with no hydrogen tanks.

Stan mayer was poisoned March 98'. He died in the parking lot of a restaurant in his home town of Grove City, Ohio. Sharks came a week later and stole the the dune buggy and all of his experimental equipment, according to his brother, Steve. Stan said while he was alive, that he was threatened many times and would not sell out to Arab Oil Corp. Stanley said he was offered a billion dollars from an Arab to basically shelf his idea. Stan said, "no, this technology is for the people."

I think he was poisoned by a hitman hired by a big oil corp cos we all no the world runs on oil and a car running on water means no income for the oil corps.

 

Ah yes... The required conspiracy theory. I'm surprised that the thread went this long without one...

Electrolysis requires energy from an outside source to turn water into hydrogen and oxygen.

Getting energy from the hydrogen is either through combustion in an internal combustion engine or through a fuel cell, either of which result in water.

However, the energy we get from re-oxidizing the hydrogen will never be greater than the energy it takes to split it apart from the water in the first place. In fact, it will be less, due to loss of energy as heat. See the first and second laws of Thermodynamics for discussion.
