how can we use H2O as an alternative fuel resource to replace gas?

Answer 1

I don't know but as soon as you find out let me know.

I don't know if they are urban legends or not but I have heard of people inventing cars that run off of water that have "disappeared" before the made it to the patent office.

Answer 2

Hydrogen fuel for a car has to have several things worked out in the real world before it can work into society. Yes they are explosive anytime there is H2 in the tank. 1. What about the warming of the liquid hydrogen. Refrigerated liquids require insulation and vacuum space to isolate the heat transfer to the liquid from the outside environment to the liquid that causes it the flash off to a gaseous state. Typically these require maintenance and even the design to survive being transported in a moving, bumping vehicle is going to be a challenge. 2. Lets say your Grandmother has her Hydrogen Fuel Vehicle in her garage and she only drives one day a week. Well that Hydrogen is warming at a good rate and the relief valve on the tank will vent to the garage space at some point. Yes the Hydrogen gas is lighter than air but what happens when it fills the garage and she opens the garage with her electrical garage door opener and the whole garage goes up in a blast. You cannot contain liquid hydrogen when it warms up and it is going to warm up. So maybe you 3. Lets say you go on vacation when your car is low on Hydrogen and when you come back all the Hydrogen has vented off safely but your tank is empty. Once the Hydrogen tank has warmed to room temperature the tank will require a whole lot of Hydrogen to cool the inside of the tank (Maybe 2 or 3 to 1). So how are you going to chill off the tank to get enough fuel in the tank to get you down the road? You can’t just take a gas can down and fill it up and then pour it in the cars tank and expect it to add much volume to the empty tank. Maybe you will call AAA and have them send out a 500 liter Liquid Hydrogen Dewar to cool off the tank and fill you tank. So you have wasted maybe 2 or 3 tank loads just to cool the tank. Now that is efficient! 4. Who in there right mind is going to allow an average driver or worse yet a below average driver to work with or fuel a liquid cryogen. It is not something that should be played with even if it is liquid nitrogen which is non-flammable. I am not saying to give up the efforts to use Hydrogen as a fuel, I am just saying that there are these items I bring to light and many more before H2 will replace gasoline.

Answer 3

You could use a type of hydrogen combustion engine. Run electric charges through water to split it into hydrogen and oxygen molecules and then use the hydrogen as the fuel instead of gas. Hydrogen is combustible and it would probably work basically the same way a modern internal combustion engine works. And the output energy would be more than the energy used to split the water molecules.. Hydrogen has huge energy potential.

Answer 4

Water can't directly be the source for fuel, but indirectly, yes we can use water to generate electricity... look at hydro dam for example. But also probably by taking out molecule so it become hydrogen.

Answer 5

no. you cannot get energy from water. Even if you were to split the water into hydrogen and oxygen, any energy you get from burning the hydrogen would be less than the energy used to split them.

Answer 6

You can drink it while riding your bike or walking instead of driving the car.
