Water can be elcrolyzed using for example solar panels into hydrogen and oxigen.
Hydrogen can be stored and transported similar to gas and it is possible to run modified benzine engines with hydrogen. The Italian manufacturerer FIAT already offered such cars on the German market.
A future economy based on hydrogen is already developed in detail and you can take part in congresses every year or every few years.

The problem with using water as a fuel is that you have to convert it into something that will either combust or produce some other form of usable energy. The conventional way of doing this is to break the bonds between the Hydrogen and Oxygen in order to produce a combustible gas.
One very widely misunderstood truth is that the energy required to break these bonds is not equal to the energy that one gets out when they are recombined. There are those out there who *claim* to have highly efficient processes to produce a fuel gas from water. There are even some who claim that they can generate more energy from the resulting gas than is required to break the bonds. Personally I am pretty skeptical of such claims as they would seem to violate some pretty fundamental laws of physics. OTOH, I am not so closed minded that I am unwilling to entertain the possibility.
I think that Hydrogen is a more likely clean fuel source if we can find an efficient way to safely store and distribute it.

Not directly, but if you invest electrical energy, you can split water up (it's called electrolysis) into oxygen and nitrogen. Those two then can be combined again, releasing the previously invested energy (either as heat or electricity). The whole process is like a battery.
Theoretically, there is a second possibility, we just don't have the technology for it yet: Fusion. Water could be split up, then the hydrogen could enter a nuclear fusion chamber where it becomes helium and large amounts of energy would be released. Unlike the first possibility above, this process could be self sustaining and would not require an external power source.

Anything is possible
...if the water it is forced through a high pressure nozzle, which creates an effect similar to a fire hose on a rolling or dynamic mechanism. The system could be designed to reuse 100% of the water..the concept would be like standing on a skateboard while holding a portable nozzle linked up to a hand-ranked water pump.
...may not be too efficient however, because there would be more work put in than work output from the nozzle due to the weight of the vehicle.

That might not be such a bad idea! If cars were run by water the vapor would just go into the air. it would do any harm to the atomoshere! Are you like a engineer or something! Good question, but i dont think it would work. Water would harm all the electric stuff.

Of course it could!
It would be really truely hard...but I think that some kind of converter that could extract the hydrogen from the water and let off the remaining oxygen would be the key. The only problem is that this most likely could happen, but the oil industry would do anything in it's power to not see it happen.

Yes but not as it is in the form of liquid water. You would need the break the bonds between the oxygen and hydrogen to create two gases. You could then burn the two gases and use the released energy to drive a car.

cars WAYYYYYYY back in the day were originally run off of steam power. the technology then and now is still too bulky and unreliable. only way to run a car off water is through steam. running steam essentially means you'ff be sitting on a very big bomb thay may go off. it's very tricky to formulate a small efficient "motor" that can use steam but yet still be practical. previous steam cars had HUGE steam engines that weighed even more than the car.

Absolutely. Some of the first automobiles were steam powered.

That is a big negative, the engine's pistons will not work properly, but one fact is that AM/PM does mix small amounts of water in there gas and also does not filter there gas well. So as advice do not use AM/PM even though they are a couple cents cheaper it is not worth it. maybe once or twice a week.
