i am going to give this as my science project in inter high school science f@ir so can any one help me about this?can some one give me some imformation about this thing.and what should i give in that project?so what should i do?can any one tell me what to make at that project?
my plan is to give my project a name that is ”cars which run by water”
so first i will use electrolysis and divide water into oxygen and hydrogen.then the hydrogen is going to be the main fuel.
hydrogen has 1 electron and 1 proton.my theme is to get the electron out of the atom and keep that running and it will make electricity.is this proces right?

First I’d suggest you proofread and spell check you question so we can understand what you’re trying to do.
Your last sentence is more or less accurate, but that single electron means it is a very reactive element. When it reacts with another element that is short of electrons in it’s outer shell (such as oxygen) the reaction releases heat which can be used to power an internal combustion engine.
The application of direct current to a water solution adds energy to the water molecule which leads to the separation of the hydrogen and the oxygen atoms which can then be allowed to recombine and release the energy as heat.
well, im taking your question as a way to run a car from hydrogen and oxygen. on that basis i would say the heat from the combination of H2 and O2 is basically negligible and cannot solely be used in an ICE (internal combustion engine) and if you wanted to you would have to combust it, that makes sense now doesn’t it. per unit weight hydrogen is 3X more powerful than gasoline but H2 is so much less dense its hard to carry enough fuel without burdening the vehicle using it. another note is that ICE’s lost alot of their efficiency from heat making even todays engines about 23% efficient.
the solution is a fuel cell which is what i think what you are talking about in the first place. it uses the energy released from the 2H2+02=2H2O reaction and turns it into electrical energy that’s usable from the cell itself. for a full size car the issue is a fuel cell big enough and powerful enough is almost prohibitively expensive. you run the fuel cell power to batteries then to electric motors (can be upwards of 90% efficient). oh yeah, the only pollution generated is pure water.
-storing energy/H2
storing hydrogen in compressed form is dangerous and can lead to explosions is a rupture occurs.
solution is to store the H2 in a solid state Crystalline lattice that does not explode if the tank is ruptured. the only thing is that even a small tank is expensive. deriving H2 can be done via windmills or PV (photovoltaic) panels on the low/no fossil fuel usage
any further info you can email me, good luck
