Device to turn water into fuel
If you want to run your car on water, you are assured that you will not need any elaborate engine. They will simply fix a device that will let them fill their tanks with water and then drive off as if they are using gasoline. The device that will do this conversion is called a converter. A converter sells for $150.
You can buy a converter from almost any local shop. The converter will use power from your car’s battery to work. You will not need to install any other component to make the car work. The device will apply the principle of electrolysis to release the gas from the water and then use that to power the engine.
