Run you car on water

You have GOT to be kidding

Thanks, I'm already running my car on another alternate fuel...

I think LA tap water might be flammable enough...

 

This car has been running on water for years.

I have a hydrogen generator. I used to use it in my lab 30 years ago to produce hydrogen gas. Production of hydrogen gas isn't a mystery Electrical sparking of water (HOH) yields hydrogen and OH. The issue is the amount of constant electricity needed to produce the spark. The vehicle in the video was using 50 amps and hour, a lot of current for a vehicle to produce consistently. I thought of converting my generator for vehicle use but I was hesitant on damaging one of my cars.

 

If memory serves me the first person who proved it could be done was in the early 1900's and his invention was squashed by the oil companies.

 

Running our cars on something vital to human life is not a good idea. We're contaminating enough water as it is, burning the hydrogen and oxygen in it means we can't clean it and recycle it and we're going to need it somewhere down the road.

 

Let's do some basic due diligence on their statement:

Starting from one direction. 1 mole of hydrogen molecules has a volume of 22.4 liters. 55 liters per minute is 2.5 moles per minute of hydrogen gas. Hydrogen has a combustion energy of 286 kilo-Joules per mole. This results in 715 kilo-Joules per minute of energy or 12 kilo-Watts. All assuming 100% efficiency. At 750 Watts per HP, this is roughly 15 HP. This can certainly move a vehicle, but in a limited way.

Going in the other direction. 55 amps is 55 Coulombs per second. A Coulomb is 6.24x10^18 electrons. A mole of hydrogen is 6.02x10^23 molecules. It takes 2 electrons per water molecule (plus EMF or voltage of 1.23 volts) to electrolyze into a hydrogen molecule. Do the math and 55 amps will produce 0.017 moles of hydrogen molecules per minute or 0.38 liters of hydrogen per minute. Also all at 100% efficiency.

Problem. Input does not equal output. By a lot. Solution, wave your hand and talk about a resonant chamber that makes electrolysis much more efficient. About 150x more efficient! No discussion about the energy required to resonate the water. Oh, sometimes they conveniently add hydrocarbons to the hydrogen going into the engine, just "until the load demand ends".

Duh. Want to buy a bridge?

 

you and your science

 

I have a semi truck that I run a hydrogen unit on, it uses distilled water and burns about 1/2 gal. per day. I have run this for about 120,000 miles and compared with before and after mpg I have an increase of 1-mpg over that period compared to before install of the unit. I did have to add an custom alternator that I had a shop build for me that is supposed to put out 280 amps that really helped the unit work much better. this 1 mpg increase nets me a savings of about $1,000 per month in fuel cost, it works for increased fuel mileage right now but doesn't put out enough to fully power the unit down the road, I do remember in the late '70-early '80s of college students running small engines on pure water and being successful.

 

No they weren't. Engines don't run on water.

 

OK, hydrogen!

 

Does **ANYONE** really think that if cars could be run 100% on WATER that there
would be an OIL INDUSTRY and a demand for more cars like the PRIUS?

Get a CLUE! Or buy my damn London Bridge in Lake Havasu City - yep I own it and it's for sale....... PM me an offer

You know what you get when you burn hydrogen with oxygen? Water.

H2O.

I used to think it'd be cool to blast a bullet of cold oxygen into a star and turn the thing into steam. Then came the day I realized oxygen has eight times the atomic weight of hydrogen.

This is like reassembly the ashes from your fireplace into a log, it would take a lot of energy to remove all the oxidation, to try and burn the "log" again.

The original poster, is probably a jokester wanting to have some fun, that or there are some pretty dumb users around here.

 

United Nuclear in New Mexico, has a Corvette they run on H2, supplied from tanks filled with metal-hydride to absorb the gas. The hydrogen is supplied via solar-powered electrolyzer that fills the tanks. And IIRC, it takes about a day to fill one tank on the units they propose supplying.

There's also a Cobra that runs on H2, but it uses compressed gas in a tank that fills the entire trunk space. It's also a rolling bomb, just waiting to get rear-ended.

The technology seems to be available, but no one seems to be doing much to make it happen. Maybe because they can't make enough money. Maybe somebody is keeping all of them bound-up in law-suits.. who knows for sure?

This guy did it in Melbourne Australia in the 70's.

Built his own car.

Then mysteriously disappeared.

Indeed, but you don't get back out what you put in, and water is not a renewable resource currently. So until we can sail the solar system at will and rid Mars or the moons of Jupiter of their water, or until we can make water from hydrogen and oxygen easily, efficiently and cost effectively, what we got is all we got.

Neither the hydrogen nor the oxygen are consumed in the process (it's pretty hard to use up atoms outside of nuclear reactors!). They just recombine to water, and set energy free doing so - energy that you have to put in before by splitting water molecules.

 

Yup - its a loss of energy to split the water molecule, then recombine it, not a loss of water. (Assuming you had 100% combustion)

 

Guys, Yin provided a real scientific explanation of why this won't work. But it's really pretty simple. It takes a certain amount of energy to split a hydrogen molecule into hydrogen and water, or hydrogen and an OH ion/anion. So you have to put this amount of energy into water in order to split hydrogen off. That's how chemistry works... ALL chemistry (not talking about nuclear reactions here). So to get an amount of hydrogen that has X amount of energy, you have to put AT LEAST X amount of electricity into the water to get the hydrogen to split from it.

In fact, splitting the hydrogen off is not a 100% efficient process. So regardless of what you do, you will be using MORE than X energy to split water to get only X energy out of burning the hydrogen from the splitting process. If this sounds like a losing game, It IS! Most hydrogen today is made from splitting methane, CH4 into hydrogen and Carbon (mostly CO2 I'm sure in the process, for those concerned with CO2 global warming). The chemistry is the same... takes more energy to split the hydrogen than you get from the hydrogen that you're making. You can think of hydrogen as just storing energy, you have to put energy in to get less energy in the hydrogen out. Unless you can find a way to circumvent the laws of chemistry or even fundamental principle of Conservation of Energy (Energy can neither be created nor destroyed, only changed form one form to another), it's a losing game. ALWAYS.

The gobbledegook on the website is just that... a smokescreen to cover the facts. As far as burning hydrogen, hobbyists have done it in IC engines for some time. Check out the American Hydrogen Assn. website to see info. Also, locally here, Arizona Public Service used a fuel cell (in reverse) to make hydrogen from electricity, which I believe was even less efficient than just using straight electricity/electrolysis to do it. They did burn it up to certain percentages in a couple vehicles with IC engines (onboard tanks of H2). The only vehicle that I recall that they had that burned 100% hydrogen was a specially-converted european Mercedes Van that they were testing and using in conjunction with the DEA on some clean fuel test programs. I personally knew Ray Hobbs who helped manage these APS programs, and here's a 2003 article he authored that some hydrogen group posted. I'm sure more searches could provide more info on APS' program from many years ago.

Hey Brian!! Hope you're doing great, and that you'll have some quality time at home over the holidays! I wonder if your system somehow changes (I suspect increases) the combustion temp and efficiency in your engine and results in small % increases. At any rate, if it works, do it! Hope we get to see you around here from a C&C some time. Merry Christmas!

 

Screw all this mumbo jumbo energy crap.
I just bought a machine that when I put a quarter in it spits out a dollar bill.
See Ya Suckers !!!
