How could you possibly run your car on water? If you buy Water4Gas, a helpful and inexpensive manual, it can explain in-depth how water can be converted into a sort of fuel that is used in conjunction with the regular gas you put in your vehicle, making it get more miles to the gallon. The manual will explain how to convert your vehicle to convert water into something powerful called “Brown’s gas”, which is two parts hydrogen and one part oxygen instead of the other way around. While “Brown’s gas” cannot be used alone to power a vehicle, it can cut your current gasoline expenses by as much as half.
