I believe that it would be powered by nuclear fusion of oxygen and hydrogen which would release energy because they are low mass elements. This would result in a byproduct of water I'm pretty sure. Water isn't considered a pollutant.
trees they make oxygen
Hydrogen and oxygen readily combine, releasing energy. If you have ever heard of hydrogen powered cars--this is how they expect to run. The oxygen is freely available in the atmosphere via photosynthesis. The hydrogen, however, must be cracked from water (a net loss) or from hydrocarbons--the chief source of which is fossil fuel.
Nope. Jupiter's atmosphere contains hydrogen and helium.
Yes, the atmosphere contains trace amounts of hydrogen gas, but it is primarily composed of nitrogen (78%) and oxygen (21%). Hydrogen gas is much less abundant in the atmosphere compared to nitrogen and oxygen.
in the atmosphere nitrogen and oxygen hydrogen and oxygen
No. It is composed mainly of hydrogen and helium. It is about 1% oxygen.
No, Earth's atmosphere is mostly composed of nitrogen (about 78%) and oxygen (about 21%). Hydrogen makes up a very small fraction of Earth's atmosphere, less than 0.1%.
We can use hydrogen to power cars, as it is clean fuel and will not pollute the atmosphere. However, oxygen and hydrogen have such a strong bond, they are very hard to separate, and at present possibly use more energy to separate thna hte hydrogen actually gives. Anoter problem is storing it, as it is very explosive, and will easily react with oxygen to make water before it's been used. :)
No. Jupiter's atmosphere is mostly hydrogen and helium with no free oxygen.
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.
There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.
Nitrogen and hydrogen, and of course, oxygen :)
