Question

Is it possible to use water for fuel,if you seperate the oxygen from the hydrogen?

Answer 1

The fuel cell is like electrolysis in reverse.  Electrolysis uses electrical current to split water into hydrogen and oxygen from acidified water.  In a fuel cell gaseous hydrogen and oxygen recombine in the fuel cell to give electrical current.  Burning hydrogen is not an option as the energy is release too quicl and cannot be stored.  

The main barrier to using this technology is the size and weight of the equipment and batteries for normally sized cars.

Answer 2

This is called Hydrogen fuel, and it is considered the fuel of the future, but there are still many technical issues to be solved before we could have mass production of hydrogen cars.

Answer 3

This can be done and its a good idea if solar power is used to do the job of splitting the water into hydrogen and oxygen. It also makes sense for nuclear power and is a lot better than how nuclear power is now used.

Answer 4

Fresh clean water is a scarce resource.  There's not enough to burn it for fuel.

Separating  water to hydrogen and oxygen require more energy than you get back and creates water vapor, a more powerful green house gas than co2.

Answer 5

Yes we can do electolysis of water in which water breaks up into its two constituent elements and gives out oxygen and hydrogen. Both these elements can turn out to be good fuels. But the main thing to be noted is that hydrogen has a very large calorific value; which means that it releases lot of heat when burnt and this heat is uncontrollable. The engine which can use hrdrogen as a fuel is also very expensive and thus not affordable by all. So people are trying to make hydrogen an effecient fuel and it will be a big success sooner or later.

Answer 6

YOU ARE A GENIUS, thats incredible, we could use the water after we get rid of the d**n hydrogen...of course!! what a break through..

Answer 7

Yes, but you would technically be using the hydrogen as fuel, not water.

Answer 8

yes

Answer 9

yes, the process is called electrolisis (i spelled it wrong) and if you use a P.E.M fuel cell you can revert it back to water again so it is never ending, QUITE EFFICIENT!!!!

Thames and Kosmos has a little toy car that uses that and comes with all the required stuff you need to make one. (Hydrogen Fuel Cell) availible at Target in the Toy/ Lego section

Answer 10

This would not be using water for fuel, it would be using water as the raw material for the production of a fuel (hydrogen).

Answer 11

Yes it is and the hydrogen is then burned to make Water which is absolutely pure. How is that for a waste product!

Answer 12

If I remember correctly, it takes more energy to split the water molecule into hydrogen and oxygen gas, than the combustion of the hydrogen produces - so it's not a perpetual energy machine.
