anything as long it is related as engine or motor
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.
Yes. See link below.
You could build one today. I also hear that at least one Hydrogen powered car reached the US Market. Check with a Honda dealer or any dealer to see if there are any models available.
Like a gas combustion engine, a hydrogen engine relies on the combustion process - in this case, combustion that results when hydrogen is combined with oxygen. Fuel cells in a hydrogen-powered car then convert this mechanical energy into electrical energy.
The first person to build a gas engine was built by Daimler or Karl Benz.
You could make one that ran off hydrogen.
Cars which run on Hydrogen are more commonly confused with water-powered cars. So, Per see, the car is dubbed "water powered" because the car extracts the hydrogen from the water and uses the gas to run its' engine. It does this by splitting the oxygen from the Hydrogen/water by way of electrolisys in a small tank in the boot, feeding the engine in the same way as a petrol powered car. But a Hydrogen powered car uses only one or two moving parts in the engine. For alot of people, the thought of the worlds' fuel resources deminishing would be the end of the automobile. And efforts to design a new engine/fuel cell were proving very difficult until the Hydrogen cell was introduced not too long ago. Many, if not all, are hailing the design as the saviour of mankind. http://news.bbc.co.uk/2/hi/business/7456141.stm
They are either powered by a turbine engine like a jet engine or a piston engine.
They used strong, light, and flexible material. The plane was powered by a simple four cylinder engine.
Airplane is a device powered either by a piston engine and prop or by a jet engine.
Hydrogen-powered airships are not commonly used today due to safety concerns related to the flammability of hydrogen gas. Most modern airships utilize helium gas instead, which is non-flammable.
