  1. No don't think so. They are coming out with battery operatiing cars though in the future.


  2. What your talking about is the hydrogen fuel cell car, it uses the hydrogen (oddly enough) to generate electricity. Unfortunatly this means storing Hydrogen in a tank, which is very dangerous unless you keep it as a liquid which is rediculous for a family car.

    The other option is storing it as water and splitting it into Hydrogen and Oxygen, but this actually takes as much energy as you get out of the fuel cell. Net gain = 0.

  3. No such thing.. at the moment, do you mean hydrogen cars? there already made.. there just figuring out how to make it cost effect. But in a way it will be a water car, they put water in a tank and it reacts with a compound to make the hyrogen. Right now the tank needs to be replaced once the "fizz" is gone and its pretty expensive.

  4. I wish! I think it is possible, since water does generate a lot of power.  If you have ever seen that one tv show with the guys from Xfiles, I can't remember the name, but they had one espisode where they discovered the first and only  known water powered car.  Who knows, one might already exist!

  5. No.

    It takes at least as much energy to get the hydrogen to separate from water as you could get back by burning the hydrogen as fuel. (even in a fuel cell)

    Since there are ALWAYS losses involved in the practical application of power production... the result is its impossible to make an efficient car powered by water.

    The first law of thermodynamics says it just won't work.

    Energy can not be created or destroyed, it can only be moved or changed in form.

  6. UNDER CONSIDERATION!

  7. I gather you know what steam is?. The first automobiles were steam (water) powered. Check the etymology for the word automobile.

  8. In a way yes. You could have wave energy power stations charge up batteries, which could then drive you around. Otherwise there is very little energy in water.

    There is actually some energy in water which can be seen by an experiment where you have a little bobbing duck on the edge of a glass which dips its beak in the water periodically. As the water evaporates, it gives the little duck slightly more momentum, and thus the duck keeps going until the water is empty.

    Quite a cool little experiment. But the amount of energy available through evaporation is very little and almost impossible to harness.

    Water H2O as mentioned above can be split using electricity into oxygen and hydrogen, (which is explosive) and used in fuel cells to drive a car. The end product is water again. However the water is not powering the car, but being used as a vehicle for that energy.

  9. only when petrol is scarce, the worlds economy would more than likely go bust if petrol sales stopped !

  10. so people claim to, but what they are doing is breaking water and forming hyudrogen, so its not really getting energy from water its getting energy initially from electricity and in the process losing energy so in my consideration this manner of operation is just silly

  11. No it's an old, old con - Henry Ford fell for it! It still persists amongst woo-woo zero-point merchants - hence the X-files reference.

    Of course, Water can be broken down to give Hydrogen, which is a clean and efficient fuel, but someone will need to develop a method of producing Hydrogen from water than uses less energy than the Hydrogen will produce - that's quite a challenge!

  12. Steam locomotives exist. Invented by James Watt.

  13. They already do.  They are actually hydrogen powered, but the hydrogen is separated from water through electrolysis.

  14. They do exists.

                               Water is made of oxygen & hydrogen.

    there is a place in hampshire that has found a way to strip the hydrogen out of water to use to run cars.

    the exhaust fumes are pure oxygen.

    the place is called area 51.

  15. lol If they did they would start taxing water!

  16. Water powered cars as u think would be a electric car in a sense . It would require a large generator to supply the power to convert the water to hydrogen . The water conversion is not very efficient.

  17. No, can't be done.  Please stop asking.

  18. na.  dont think a  "water station" instead of "gas station" sounds right.

  19. They already do, but you need electricity to break the water down. Hydrogen fuel cell cars are basically just water powered. Very inefficient still, and expensive to operate.

  20. They DO exist. Type 'water powered car' in google and see one.  I just looked 4 days ago and found one.
