How do you build a water powered engine?

Answer:
Well directly a water powered engine hasn't yet been invented, but indirectly it has. By putting H2O through electrolysis you can separate its two components into H(2) and O. The hydrogen can then be used to fuel a hydrogen fuel cell engine while the Oxygen will be emitted harmlessly into the atmosphere. after the engine uses the Hydrogen, it will dispose of it and the hydrogen can effectively react with the Oxygen in the atmosphere to re create water. this water can be recycled to begin the process again and in theory, you could create an engine with infinite power on as little as a gallon of water.
