Question

So someone told me that they invented a car that runs on water is that true????

Answer 1

Someone told me that too. And they've mastered cold fusion, by the way!

Answer 2

Yeah.

...and you can live on water also.

Some say you can separate the H2 from the H2O (water) and run an engine on it. You can. But it takes more energy to d it than it produces.

Answer 3

Its funny....I remember watching a movie back in about 3rd of 4th grade about cars that would run on water.   I'm 39 now and still haven't seen it happen yet.

Answer 4

in theroy, yes.

if you can compress the water in some way to turn the drvie shaft, but chances are its a waste of time, because you would have to have alot of extra equipment that would use fuel ineficently, it wouldnt work so great.

Answer 5

Heat the water and it becomes steam.They call it a Stanely Steamer. It was invented a long time ago.

Answer 6

The air car is much more feasible and in production in France already....as is the electric car.  Toyota can't keep up with the battery demand and is working on new lithium batteries for the next generation of vehicles.  Why wouldn't a water power car be possible.  EVERYTHING is possible...feasible and practical is another thing.

Oh ye of little vision.

Answer 7

Yes!  Santa Claus and the Easter Bunny will hand them out soon!

Answer 8

Only if they're able to break the laws of physics. It takes more energy to remove the hydrogen from the water than they can get back out using the hydrogen as fuel.

Answer 9

Most likely the person was referring to 'fuel cell technology' which is sometimes mistaken (or simplified) with water.

Fuel cell technology as being researched and tested in the auto industry is based on Hydrogen, the H in H2O (=water) and the by product of this technology is heat and water. This explains the common misnomer that the cars run on water (although it is pretty close!)

Directly from the wiki page, in case you'd like to understand the technicalities behind it:

It produces electricity from various external quantities of fuel (on the anode side) and an oxidant (on the cathode side). These react in the presence of an electrolyte. Generally, the reactants flow in and reaction products flow out while the electrolyte remains in the cell. Fuel cells can operate virtually continuously as long as the necessary flows are maintained.

Fuel cells are different from batteries in that they consume reactant, which must be replenished, whereas batteries store electrical energy chemically in a closed system. Additionally, while the electrodes within a battery react and change as a battery is charged or discharged, a fuel cell's electrodes are catalytic and relatively stable.

Many combinations of fuel and oxidant are possible. A hydrogen cell uses hydrogen as fuel and oxygen as oxidant.
