thermodynamics friends. this is garbage. snake oil. fizz.

Prove it.

yesplease in short two H2s + one O2 together will have a chemical reaction (fire, in this case) to form two H2O molecules. What is called the delta heat of fusion is the difference of the potential energy (or stored heat) between the two discrete H2s + the one discrete O2 versus the potential energy of the 2 discrete Water molecules. This delta heat of fusion is the same whether you are burning H2 + O2 to form water or using electrolysis to break the water molecule back into to its component parts of Hydrogen and Oxygen. The problem that should be obvious for you at this point is that in a purely biblically perfect conversion process you will not have released any more heat (energy) than what you put into the process in the first place. In the real world (not the one that was created in 6 days) no person has ever developed any kind of system that does not suffer from heat loss. If this is not sufficient proof for you then you should consider taking a course in Chemistry or Physics and have a blast arguing with the Instructor.

And watch out for Snake Oil salesmen in the future. This particular scam has been around for at least 100 years.

velodog nailed it.

For a humbler example I offer a question.

Premise is that a three dimensional and multi sided solid may be constructed to be unstable on at least one of its sides. That is to say that if a person places that solid down on a flat table, the solid body will topple off the unstable side onto another side.

Question is whether or not a solid body can be constructed to be unstable on all its sides?

just-me, there is so much mutually supporting empirical evidence, from the layout of the Periodic Table (it's not random), to things like stoichemitry, titration, carbon bonding, hydrogen bonding ( this tells you why H2O is a liquid @ a molecular mass of only18). Avagadro's number has been consistently empirically correct for almost 200 years now. The fault with statements like the one above is that there are experiments done in High schools and Colleges everyday that illustrate titration, equivalents, calculating unknowns etc. , that are not being overseen by evil Oil company operatives, and further, such experiments show consistent, repeatable results. Chemistry IS an exact science.

What this thread demonstrates with sad precision is that our eduction system is so horribly off base that with its assistance even aspies become uncritical thinkers. The ignorance in modern society is at a professional level.

Such persons not only believe in water power, but 200 mpg carburettors, ozone holes, man made global warming, and that the WTC towers were brought down with demolition charges. Might as well bring back bleeding witch doctors. Wait! We have, they sell magic potions and are all over the telly on infomercials.

Of course converting energy to different forms will incur significant conversion losses, I'm not arguing it won't. The point is, whether or not the differences in BSFC (IE thermodynamic efficiency of the engine) will outweigh the conversion losses. Like I said, similar could be accomplished via changes in gearing. Or a battery powered hybrid system. Go have a gander at a BSFC map for a SI engine, as well as the literature on Hydrogen/gasoline combustion, and you may see why something like this could net significantly better mileage at low loads, eg a 50% reduction in idle fuel consumption.

Not exactly. At least, not AFAIK... Stating the car runs on water is sufficiently vague as to arouse media attention, w/o being wrong per say. What the creator of the car said is imprecise to the point of useless from any scientific perspective. They may be attempting to sell snake oil, or just garner interest for yet another form of load maximization/onboard energy storage.

yesplease, for me the fact that they are claiming to break up water back into Hydrogen and Oxygen, so they can then burn the Hydrogen and Oxygen back into water brings up the question "Why not take the energy that you would be putting into the process of electrolysis, and use that energy in a more direct fashion to power the motor?". Anyway, I need to practice posting links, but if you do a search using "Warning: The Hydrogen Economy May Be More Distant Than It Appears" you will get a Popular Science article from 3-24-06 that will discuss some of the problems that need to be overcome before Fuel Cells can be used practically on a large number of vehicles. Electrolysis can probably be made practical using what would be wasted power in Nuclear or Hydroelectric Generation Plants. Having a portable electrolysis unit on a vehicle powered by an outside source (solar?) again begs the question : Why not apply the power directly to the vehicle?

If this can actually be done in a practical, affordable fashion in the next 35 years I will be very surprised. I have had to eat crow before, but I don't believe this is one of those times.

There has been a car powered by water out there of ready for about ten years or so ,a man in the Philippines I think, it was the first water car, I think you can find a clip on youtube.

kim commando the computer goddess on AM radio had a little thing about some company spending millions of dollars or even a billion on a water car claimed that they had the first and only car powered by water . They failed to give credit to the man in the Philippines for actually developing it first,in essence stealing the credit.

I thought I would put this tidbit out.

Is that you JerryHatake or did some guy named soon steal your picture?

Even if you burn the hydrogen in excess oxygen so as to up the percent yield, you're still using the vapor pressure of the steam to drive the piston. Also, you will need a lot of H2 gas as the energy in the H-H bond isn't as great as a C-H bond, meaning either a large tank (increasing wind resistance) or high pressure (meaning a physical hazard.)

Will it run on ocean water? If not congratulations to the person for inventing a car that runs on another natural resource that is getting more difficult to find enough of.

There are already water wars in some countries.

Salt water decomposes more readily than water with a lower ionic content... but this post just ignores all previous posts. As well as the hydrologic cycle.

who is JerryHatake?

iamnotaparakeet, what is the English translation of your sig line?
