Water cars really exist
Yes, they do. It is not science fiction. Water cars really exist. In principle, it is a reality that you can use water 4 gas. You can run your car on water. There is no reason why water cars cannot exist. The process through which a water car produces fuel is the same one as a gasoline. Both of them use gases to power the car. Gasoline will burn just as hydrogen.
By water car we mean a car that will take water as input and then convert the water into hydrogen. Hydrogen burns just like gasoline and makes an efficient fuel. You may want to know that hydrogen gas can be recycled over and over again to give recurring fuel for the engine. Water cars really exist and will give more mileage.
