fuel working on its own emission

does anybody know of any fuels, or possible inventions, which would allow fuel to work on its own emissions time and time again.

Thanks in advance

As far as our current fuel technology is concerned, no.

Here is the current model for chemistry and energy:

You have chemicals that are High in Energy. You burn them, they release the energy, and they convert into chemicals that are Low in Energy. The only way to convert the Low Energy chemicals back into High Energy molecules is to use up more energy from somewhere else and put that energy into the Low Energy chemicals. (I said energy too much)

Example: You use up your battery. The chemicals have been "used up." You plug the battery into the recharger and use electrical energy to build up the chemical energy in the battery. Of course, something else had to happen to make that electrical energy, such as using more fuels.

As far a gasoline is concerned, its energy is used by Combustion, which is a violent and fiery version of oxidation. Gasoline is in a reduced form. Burning it with air converts it to carbon dioxide (ideally), which is as oxidized as any carbon molecule can get. The carbon dioxide and other oxidized chemicals coming out of the car cannot be burned or combusted any more, and must be built back up. This takes at least 65 million years under normal natural conditions.

This is true for humans, too, for the exact same reason. Sugar and Oxygen are both reduced molecules. They are both oxidized completely until they are broken down into water and carbon dioxide. For the same reason that cars cannot run off of their exhaust, humans cannot live in carbon dioxide.

Ideal solution: Hydrogen fuel. Hydrogen and oxygen are combined in a Platinum or Palladium chamber where they are compressed. The Pt or Pd acts as a catalyst and causes the H2 and O2 to combine into H2O, water (balanced chemical equation not included). This releases TONS of energy. The water produced should be collected in an exhaust canister which is dropped off when you go in for a refill. This water is taken back to the original source of the Hydrogen gas, which is a solar-powered plant that splits water back into H2 and O2.

Nuclear submarines already take ocean water and convert it into breathable oxygen while submersed (as discussed on the History Channel). We aren't going to be living under the sea for quite some time, so let's just use solar power. In this way, our hydrogen-processing plant doesn't have to burn fuel to run - it can just use the sun, which is still good for at least another two billion years.

thanks for the in-depth answer

"fuel working on its own emission"

Seems to me that describes a nuclear reactor very well. Did you intend
that to qualify as an answer ?
