You can drive up to twice as far with the same amount of gas you are using today to go half that distance. You might think it is impossible but once you know how to run a car on water, you will be making less trips to the gas station which will be better for your wallet and your emissions will be nothing more than water and oxygen, which is better for the environment. My husband used to have to fill up twice a month just to go back and forth to work, now he only fills up once a month.
