I keep wondering what the long term outcome of having a half billion hydrogen cars spewing 02 and water vapor into the atmosphere would be.
Not good, I think.
Shame on you for thinking long term !!!!!
Well shiiiit! Kirk should be happier than tits on a boar hog now that the North Pole is melting there will be enough water to go around for everyones car!
YEA GLOBAL WARMING!

I think hydrogen cars are NOT the future, folks.
But then too, I didn't think Motown had legs, either.
Now I'm no scientiest, but considering that water vapor is a green-house gas, wouldn't water-powered cars be just as bad? Water-vapor absorbs more heat than CO2. And honestly, people are already fighting over water to drink. I personally, don't care to start fighting over water to fuel my car.
If there is something to this, can you imagine? These guy better keep their technology close to the vest otherwise Exxon or Shell will show up at their door. They have gotten used to their blotted profits and certainly don't want to see anything that might stop the flow of money.
Thought just occured to me.
In order to run on H2O it has to be distilled water.
Also there's the question of what the effect of huge amounts of O2 would be on the atmosphere, too.
Because 02 would be the by product of breaking down those molecules would it not?
200,000,000 vehicles spewing flammable o2 into the atmosphere?
Sounds like that's a problem waiting to manifest to me.
The solution is STILL solar, folks.

Water vaper condenses into liquid and falls to the ground. CO2 doesn't. Not that I believe in man made global warming. And besides which, imagine the water vapor from H2 cars compared to the utter vastness of our oceans.
Well you can't very well use solar for transportation. Not without a storage medium (batteries, compressed air, hydrogen), anyhow.
There is a finite amount of energy in a square meter of sunlight. I want to say...700 watts or so, for southern states on a sunny summer day. For reference, 1 HP = 746 watts. And remember that solar panels are only 15% efficient or so. So you'd be lucky to get even 1 horsepower if your car was covered in solar panels.
There is no O2 being spewed. Only water vapor.
The H2 manufacturing plant takes in water and a buttload of electricity, and yields H2 which is stored. It also yields O2, but that's released into the air.
Now image the water vaporour effect of a half million cars spewing water vapor in the canyons of NYC. Every day will be a foggy day in the big Apple. Sounds silly now, but I honestly think that much water vapor would be an environmentla problem for us. Not a glabal environmental problem but a problem in place.
Is that 700 watts of power per sq meter, per hour? Per day or what?
My chemistry is a little rusty, but I think that the products coming from Electrolysis of water are one hydrogen atom and two oxygen atoms, yes?
So the question remains on the table:
What do we do with the spare 02 after we break down the water molecule?
And while I'm willing to listen to any and every plan anyone has to help us get through the transation from carbon based energy sources, I think solar. geothermal and (perhaps) tidal energy has got to be the solutions we need to invest our resources finding.

Also, water can be moved in pipelines just like oil if it's really scarce.
If the oil companies were all-powerful, we wouldn't have corporate average fuel economy (CAFE) regulations, and the 80's wouldn't have been so painful for oil companies.

The H2 manufacturing plant takes in water and a buttload of electricity, and yields H2 which is stored. It also yields O2, but that's released into the air.
Then later on, your car combines the H2 with the O2 in the air, making water vapor. Just like burning it. The result is, you get back some of the energy that the H2 plant put into it. About 40%, on par with a good diesel.
In other words, H2 is just a storage medium, like a battery. Except that batteries are considerably more efficient with regards to energy. That's why most EV enthusiasts now see lithium batteries as the new hotness, and tend to dismiss H2 plans as windowdressing gimmicks by carmakers, as well as a moneymaking scheme by oil companies (currently, H2 is almost entirely made from natural gas and not water).
SUNRGI says it can multiply that by four because it has a system to instantly cool its germanium-based semiconductor from 3,300 degrees to 20 degrees above ambient temperature.
A further advantage of PS I is said to be its transparency to infrared radiation, which eliminates the need for expensive cooling equipment.
Think of it like this:
H2 manufacturing: splits water, puts +100 oxygen into the air
Your car using up H2: recombines H2 + O2 into water, removing -100 oxygen from the air
