Can water be a source of energy in motor vehicles ?

Question

For cost cutting and cleaner environment !

Answer 1

Must separate the Hydrogen, then Hydrogen fuel cell

Answer 2

In a word, no. Water is a combustion product, not a fuel.
It can be dissociated into hydrogen and oxygen, which can then be recombined (burned) to produce energy, but the energy it takes to separate the hydrogen and oxygen is more than you get out of it by burning, and must come from a different source.

So much for the cost cutting. cleaner environment? Not unless you use Solar, wind, or geothermal (or nuclear) to dissociate the hydrogen and oxygen. The absolute most you can get out of Solar is 1,366 watts/m^2. At 746 watts /horsepower, that's 1.83hp/m^2. We want somewhere around 250 hp in our cars (500hp for high-performance BMW's), so that means 136.61 m^2, or about 12m x 12m of 100% efficient solar panel.

Answer 3

I doubt. Water as it is cannot let out energy to run on a moving transport. By producing steam from water we can use for running vehicles. But it needs fuel. Any fuel except stored electricity or solar energy requires space and it may cost more. Certainly it will not save environment.

Answer 4

It already has been used in steam engines 100 years ago. But you would need some other type of fuel to heat the water and create steam. So water powered vehicles wouln not only deplete our water supply, but also use up other fuels (coal, wood, etc.) and these other fuels would create just as much, if not more, pollution as today's cars do

Answer 5

Yes. Water can be decomposed into oxygen and hydrogen which is a source of energy. Some vehicles are already powered by hydrogen.

Answer 6

its possible but youd have to worry about the hot water, youd lack performance in your car but i could be wrong... youd also have a problem with what kind of water and how much fresh water? salt water?. Youd end up using our water sources just to fuel your car then what would we drink? If you used salt water it would start to corrode the engine. cleaner YES cost cutting depends, water supply would go down and demand would go up causing water prices to fluctuate.

Answer 7

yes,in motor water is heated during driving & heat is converted into kinetic energy which helps to running the motor.

Answer 8

yes by using electrolysis to separate the hydrogen molecules which can be used as fuel.

Answer 9

Yup , but not all ppl use such kind of vehicles , sad :(
I hope they'll cause it'll be better for our ecology too!:)

Answer 10

no
