That is very misleading. You need electricity to seperate the hydrogen from oxygen so in essence, you are buying an electric car.
By that same logic I am driving an "electric car" now, as electricity is used to ignite the gas fumes that drive the pistons, that turn the wheels on my gas guzzling SUV.
There is a level of efficiency. Although you need electricity to break down water into its component parts, the break down of the bond between the hydrogen and oxygen will release more electricity than is used. Potentially enough to run the car and charge a battery so you can get the car started.
You are wrong on many levels. First of all, energy is used to break bonds and energy is released when they are formed. Secondly, the amount of energy you put in to break the bonds is what you get when you release them. Water is used as means for transporting hydrogen because no one has been able to store it efficiently yet. Just some chemistry for you.
Fueling stations for hydrogen aren't so uncommon anymore actually.it seem's they are the only fueling stations and are very limited
