Could Oxygen gas be used as a fuel source?
I was specifically thinking of the products in electrolysis of water. The hydrogen gas produced from this process could (potentially) be used as a fuel source, but what of the waste oxygen?
O2 gas is what makes everything burn, so could a car or electric generator be powered by pure oxygen?
No! You need something that ‘burns’ in the oxygen. Hydrolysing water to get Hydrogen is wasteful as the oxygen is available from the atmosphere.
Did you see the guy who had a LPG powered car had a leak and when he lit a cigarette blew himself and the car up? Hydrogen is even more of a problem as it cannot be liquefied at reasonable pressures and is stored cryogenically – extremely cold. It boils off slowly even in very well insulated vessels and you get a garage or car full of Hydrogen which makes a lovely bang if there is a spark or hot object nearby.
Nearly all ‘good ideas’ for different fuel sources have a down side and many are less efficient than burning oil or coal directly. Losses throughout the system add up. You cannot say because the FINAL use is wonderfully efficient it is overall.

Yes, it could. Current car engines rely on mini explosions to push pistons to turn motors. Oxygen, as a flammable gas, could be used in creating these explosions instead of gasoline. Unfortunately, producing O2 gas takes an inefficient amount of energy.

yes but why wast it

A car running on pure O2 has already been created. The thing is they had to make it uber light so it could move. The whole thing is made of plastic and hot glue. It a complete saftey hazard and NO ONE should use it!!

Actually no, oxygen is the "oxidizer" that combines with the fuel, not the fuel itself.

dude, if you put a mach in it, and it flames it up, it’s defenitally a fuel source!!!

NO, NO, NO Remember, to have fire you need fuel, oxygen, and ignition source. pure O2 doesn’t burn. There is a great video on the web where they pour liquid O2 on hot coal. The hot coals have fuel and ignition, but they are smothered and have little O2. When the liquid O2 at -300F hits the coals. Boom, the reaction is so quick and the heat so high, the steel tray "burns" there is enough O2 and heat that the Fe in the steel pan immediately turns to Fe3O8 a pile of rust.
That is what happens if you feed a fire in a an engine with pure O2, the engine burns.

No. Oxygen needs a fuel to burn. You would probably need to construct your engine out of some exotic materials to prevent it from melting if you wanted to use just hydrogen and oxygen.

why think of oxygen as waste particles, you can use it in medical resources and you can usr it too. Cant you feel that oxygen is your blood….

No.
Pure oxygen is not a fuel and will not burn.
You need to mix oxygen with a fuel to get flame.
Pure Hydrogen is a fuel but will not burn without Oxygen.

O2 is not a fuel. Go back to school the electrolysis of water is not feasible as a fuel. U can not get power from nothing. It takes 300% more power from your battery than it will cost U to recharge the battery .
