Interesting topic. What is your question? Are you asking for more information on the topic?

Your project should pose a question. In this case it is about water power and hydropower.

To see if water as fuel in cars and aeroplanes I suggest searching the internet for "water power" and/or "hydropower" and see what you come up with. However, to my knowledge there is no such technology that exists at the moment (using only water as the energy source) so I suggest that your modify your project question after you do a little more research and understand the topic better.

Another interesting approach to this project would be to research Fuel Cells, which can be powered by oxygen and hydrogen gas, and therefore can indirectly be powered by water. Fuel cells generate an electrical current that could power an electric motor or other device.

The water would first have to be split into its component atoms through electrolysis through the reaction H2O -> H2 + O2 (numbers would be written as subscripts). The resulting hydrogen and oxygen (H2 and O2) gases could then be used to power a fuel cell.

You may want to look at this article from Howstuffworks which discusses some basic principles of fuel cells

And this article which discusses both the electrolysis of water and fuel cells in a bit more depth

I hope this helps, but please post another message if you need some more help.

There is a site where they tell you how to build water fuel cells.

it might help. Good luck!

When you use the term FUEL, the general meaning is to define a source of energy. Oil, gas, and wood are generally defined as fuel in the sense that they contain energy that can be released through disassociation of their component molecules and the resulting hydrogen and carbon can be burned with oxygen to produce heat.

Combustion of the hydrogen results in water and combustion of the carbon results in carbon dioxide. These correspond to the waste products from a fire.

Ask your science teacher about energy states and entropy. In terms of water as a fuel, the traditional definition is that water is not a fuel source.

If you want to explore breaking the water back into hydrogen and oxyten, then you are talking about making fuel from water. That requires an energy source to do the work of breaking the chemical bonds that hold water together.

If you want to explore hydrogen fusion, the water is essentially irrelevant. It is simply a convenient place to find hydrogen.
