Actually, water can be used as a fuel. Electrolysis can break down the water into hydrogen and oxygen. Hydrogen fuel cells can then use the hydrogen as a fuel. The waste product produced from the combustion of hydrogen is water. This water can then be used once again--due to the water cycle, hydrogen as a fuel would be renewable. As fossil fuels begin to run out during this century, hydrogen fuel will be a viable way to obtain energy.

Yes! Water is used as a fuel in our body.

 

we cannot survive without water.

In perhaps an indirect way, water is used as a fuel in dams. We can use hydroelectric dams to harness the power of water to fuel our electricity. You may not be able to burn water as fuel in your car, but it is actually very useful and we should be using more in creating electricity.

Water is a fuel to generate electricity. Here is a following activity to proof that water can be used as electricity -


* Run a tap 

* You need a strong magnet

* Roll 124 loops of copper wires around it.

* Put the electromagnet under the tap through which water flowing




You are done -

 

After that make any circuit for example a bulb.

 

The bulb will glow.

 

TRY IT!!!!!!!!

I think water cannot be used as a fuel because it does not have any energy to run any vehicle. Niether does it support combustion nor does it take part in combustion. The process of combustion is neccesary to run a vehicle. If water it electrolysed to Hydrogen and Oxygen molecules then only will it be able to act as afuel. But for electrolysis continious supply of electricity is needed which a vehicle cannot provide.

Cold Fusion -

Cold fusion is proposed type of nuclear fusion that could occur at or near room temperature in the millions of degrees that is required for hot fusion. As a new type of nuclear fusion.

I tried one more experiment in  my home on the topic '' Water as Fuel .''

 

And I was succesfull in my experiment.

 

My Experiment-



Start a normal wood fire, place a metal plate over it and let the oil and the water drip onto the plate to the side of the plate in a ratio of three drops of water and one drop of oil.


The oil should be motor oil.



I understood by this experiment that the fire was so hot because the water dissolated the heat of the plate and burning oil and went right to the combustion of the oil and hydrogen joined up with oxygen.

 

Thank You.

In reply to 6 & 7:

In generation electricity through dams or using tap water, we are using potential energy of water due to its height which is converted to kinetic energy and in pipe and subsequently in to electrical energy. This is not using water as fuel.

Fuels use the chemical energy of the substance and hence thse examples are not valid.

In reply to 8 & 10:

Steam engines use the chemical energy of fuel (coal) to raise steam and hence chemical energy is converted in to heat energy and transferred to water/steam. Water is not used as fuel in a steam engine but as a medium for storing heat energy to drive the engine where heat energy stored in steam is converted in to mechanical energy of the engine.

In the experiment at 10, the heat of wood fire does every thing described in the experiment. The wood is the fuel in this case used for producing heat in the first place and not the water.

We should try to understand the processes before making conclusions.

There is another way for water to be used as a fuel. You can separate hydrogen and oxygen by use of electrolysis and then use hydrogen in nuclear fusion as in eg. H-bomb or perhaps one day cold fusion.

Water releases no energy, and cannot combust. Therefore I would find it HIGHLY implausible for a vehicle to be run on water alone. Water is commonly a product of the combustion of hydrocarbons, or in hydrogen fuel cells.

Electrolysis of water need more energy to break it in to Hydrogen and Oxygen directly so electrolysis is not the answer to use water as fuel. However, research is going on and to produce water-based fuel cells to separate Hydrogen from oxygen using catalyst. This technology can be used for no-carbon emmission cars.

As of today, I don't have any example of using water as fuel. And the reason has be given in my post #4. We have yet to see how it can be used in future.

An H-Bomb? No thank you, we had enough of that in the Cold War.

But do you mind explaining what cold fusion is? sounds interesting.

The nuclear energy that we use now is called FISSION. What we do is we get a typically very dense metal (e.g uranium 235) which is unstable. We put it in a reactor and bombard it with particles (neutrons). Then, the atoms of the metal break down and in doing so release energy as heat. 

FUSION is the opposite, we use a very light element (hydrogen) and push it together with another one with enough force so that they fuse. This releases a vast amount of energy, and is how the sun makes all its energy.

So, we actually have the technology for fusion, but there is one problem. We have not found a way to use it that is efficient enough. Currently we are spending more energy (as heat) forcing together the two nuclei than it releases, so we actually lose energy. 

What we need is COLD FUSION, which is simply what we have now without all of the energy we are putting in. Or, as astrosonuthird put it, its fusion at near room temperature.

I'm assuming you mean to use the force of the water to push the magnet through the flux lines of the coil and induce a current. Even so water is not acting as a fuel. A fuel is something that stores chemical energy,

Argh. No. water is nowhere a fuel in our body. You are probably under the misconception that water *powers* our body. In fact, water is a bi-product of respiration, and that is what powers our body.

Are you just saying random words that sound sciencey? No offense,  but it's wrong. I don't even understand what you're saying. And even if I did I doubt it would make sense. Right here you say: "combustion of the oil". Therefore it is the oil that is providing the energy, not the water.
