My question is this:
Once the water is used in the vehicle, does it go back into evaporation or is that water completly burned off never to be seen again? If it were to be completly burned off, wouldn't eventually down the road we have a huge drought?

But there is a crap load of oil up there. With our oil and water, Canada is poised to be a huge player in the world in the coming decades.

Water is never completely burned away, or so I have been told.
Sounds like a cool deal, can you imagine getting thirsty in welding class and drinking out of your torch?

While it is possible to turn H2O into HH + O it takes more engery to split the elements then burning the HH + O creates.
Not to mention if you invented something this amazing do you really think you'd be driving a 94 escort???? Seriously, you'd have VC money up your a$$.

Yes you can make hydrogen from water using electrolysis and several other ways. Hydrogen is the most abundant element in the universe. But...the production of hydrogen is not as easy as sticking a car battery on the electrodes sunk in water. There are power requirements to think about. How much electricity does it take to extract X amount of hydrogen from some amount of water? And how much potential enery can then be extracted from that hydrogen? Does the power extracted from the produced hydrogen yeild enough energy to not only run the car...but produce enough electricity to continue the water electrolysis/hydrogen production at a rate to sustain both? Im not sure but I dont think so.
Mainly due to the laws of thermodynamics. I dont know the energy that is contained in a unit of hydrogen and how much electricity it could make powering an inefficent internal combustion engine to then drive generators to supply power for electrolysis. But I would think around 30% efficient if that.
The other way to look at it is how fuel cells work for electricity generation...such as on spacecraft. Its the reverse of electrolysis. O2 and H2 are combined in a similair apparatus that makes electrolysis happen...and electricity is generated. I think the efficiency of those is around 80%
Really the only difference between this and the Hydrogen fuel cells the auto manufacturers are working on is that this supposedly produced the hydrogen on the fly. So in other words you fill the tank with water and then use a small amount of stored hydrogen and a battery to start the car. Once running then use onboard alternators powered by the running hydrogen fuel engine to produce the energy required for the electrolysis to produce the hydrogen fuel and the system will continue running as long as there is water in the tank to be converted. I dont know if that is currently possible. My intitial feeling is that it is not. somewhere along the line your gonna have to plug the car in overnight and have larger storage tanks to make it an effective vehicle with any practicality.
In the hydrogen fuel cell cars GM and others are making...there will be plants that produce the hydrogen by various means...and that will be taken to what would be hydrogen "gas stations" where you would fill up your hydrogen powered car. The downside of the hydrogen fuel cell is the very high pressures it needs to be stored at to make it practical to carry enough to get similair range as a gasoline car. And the energy required to produce this hydrogen will be enormous. Unless you use atomic energy, solar or some other renuable souce...its a total trade off. You burn coal or fossil fuel to power electric plants to produce the electricity required to make hydrogen. You havent really helped much in that scenario.
I did some more digging and found some things.
the electric power required to electrolyze the hydrogen equivalent to 1 gallon of gasoline is equal to (500 moles) x (0.06587 kWh/mole) = 32.935 kWh, and the approximate cost of that power = (32.935 kWh) (@ 13.5¢/kWh) = $4.45 per 'gallon equivalent'
Converting KwHours to HpHours you multiply the KWH X 1.34
So the 32.9 KWH of energy required to convert hydrogen to the equivilent of 1 gallon of gas (for reference) would require ~44 Hp hours of energy. IOW the hyd fuel (that is equal to 1 gallon of gas) would have to sustain the internal combustion engine its running at 44 HP for 1 hour just to turn the generators enough to reproduce another quantity of hydrogen to make it run another hour. That does not inlude % of loss for the generator and drive system and also does not include PROPPELLING THE CAR...lol. Obviosuly 1 gallon of gas (or the h2 equivelent) is not going to sustain 44 hp for 1 hour...not even close.
I think for this to remotely work it would need to be plugged in at night to continue electrolysis, have a large storage tank, the electrolysis unit would have ALOT of surface area of cathode/anode to produce the required hydrogen, etc etc.
I personaly think the guy in the vid is filling a small tank on his car with hydrogen BEFORE starting and then his electrolysis macnine adds to the amount as its running...but would eventually deplete itself if left to run as it was.
But we will see.
So whats happening is the engine runs on gas and the engine turns an alternator or alternators that produce electricity for the electrolysis that in turn make hydrogen......but very small quantities.
This wont work unless a more efficient way of making much larger quantities of hydrogen is dicovered. It will likley take a catalyst...and using the catalyst will likley not make it a clean alternative. Its already more expensive than gas to make per equivelent unit.
He is not the only guy making a hydrogen gerarating welder. A quicj google search turned up several and the technolgy to do this is not new.

You can't destroy energy. All you can do is convert it from one form to another. Water converts to heat then to steam then condenses to water again.
Interesting idea, though. It would be interesting to see where this goes with the resources of an automaker behind it.
