Have you guys seen this???
Lots of power from water.

Well water is H2O.
You can split 2 molecules to 2xH2 and O2 with electricity. Now you have hydrogen and oxygen. If you 'burn' something with pure oxygen, it 'burns' very fast and hot. I think it's that good to heat metal, because the metal might react with the oxygene and/or the hydrogene...
The same type of flame or 'fuel' is used in the Spaceshuttle
But I don't understand what this HHO is. Usually it should be WATER, but they speak of it as a gas. So maybe it's steam
The problem is, that you need a lot of energy to create the hydrogene. If the electicity was created by Solar panels or wind Weels or something alike, that wouldn't be much of a problem, but if it's created from oil or coal, it's not realy worth it.

Running a car on water is different to what we're seeing in this video. Basically, a hydrogen fuel cell is just reversing the electrolysis process that is used to seperate the hydrogen from the oxygen in the first place. I'm guessing that there is a reaction happening with steel similar to what happens in thermite (look on youtube). That is why there is very little heat when it is touched, but a lot of heat with metal.
Are there any chemists here to shed some light?

hey luke! seems that there is a faster and cheaper way to do it..

What they throw in the water could be any alkali-metal (right spelled?), like kalium or natrium. That produces hydrogen since the metals furiously react with the water tieing oxygene thus releasing some hydrogen..
This should be possible no matter what. But i don't think it can be done practically during long time term. You can think of the process as a rechargeable battery. If you separate water into oxygen and hydrogen it takes power. On the other hand the power is given back when oxidizing hydrogen/oxygen, using hydrogen fuelcells or whatever. I think the principle goes for everything is this world. You cannot gain more energy out of something then what's needed to create it. The most stable material in our world (like water, dirt etc....) cannot be used as fuel since it has already reacted and finished. If you find a way to create a material that gives a lot of energy when reacting, it would probably take a lot of energy to create it or the material needed for the reaction.
Atomic fusion and fission might be the closest to "free" energy options we have. I still think that the forces needed to create for instance uranium or plutonium is somewhat close to the power given in a nuclear reactor. I'm not a physician so i really can't tell though.
cheers

You may be interrested in the following:
Nuclear fission - You can split the nucleus of an atom into two smaller fragments with a neutron.
Nuclear fusion -You can bring two smaller atoms together to form a larger one
Now the energy is created by the resultant atom (Fusion) or atoms (Fision) having a smaller total weight then the original total weight using the Einstein's equation E = MC^2 (where M is the mass and C is the Speed of light, 300,000,000 , so quite high)

i think the point behind a watercar is not the fuel efficiency but the fact that it is clean. the question is: can you split water (no matter how much energy you need, because at the end youre buying that energy, so even if it is 1:1 in this moment this is not important) without creating environmental problems? if you split the water outside of the car will it still be clean?
if the answer is no, then it might be better to search another way to move cars..

Of course, atomic energy. It's been always the solution.
In some decades we will have atomic fusion energy, in the meantime, we must take care of the radiactive wastes from atomic fission. I think that controlled radiactive waste is better than tons and tons and tons of uncontrolled wastes dumped to the air, sea and ground. We all throw poison to the air everyday without caring but think of atomic energy as unacceptable. It's just the fear to the unknown.

yes, there are a lot of way to have power from the water - only question is costs.
Looks like this guy use some way (active metals, electrolysis, heating membranes) to extract hydrogen from water. Then you can burn it to cut metals or to generate energy - of course lees than you spend
Personally I big fun of fusion energy - but I think it will take another 5-10 years before first industrial reactor.
