Hydrogen run cars mix in hydrogen with oxygen to produce water... but at the same time its charging an electric type motor, which in turn spins your axels. You will get a water vapor coming out of the exhaust... water vapor does not freeze INSTANTLY, to the point where in a traffic jam... you would make all the roads slippery.. it wont come out as liquid water.. as it will most likely be burned up producing a nice evaporation effect...
You still need a way to make hydrogen in the first place... so you still need power plants... but if there is a way to split hydrogen from water, without having to use a gasoline/coal/nuclear source... then there would be a 100% solution to our killing of the environment
The only bad thing about this source of power, is that you will be creating ALOT more rain clouds, thus possible floods in certain areas... also, I doubt they would be using much metallic parts, since any chemicals mixed into the vapor, could produce acid rain clouds... bye bye to plants and your paint job.
Also, you need to use fresh water that is clean... so that will cause us to have a shortage, which we already have a shortage by the way. Though I dont know if the rain will be 100% clean... if it is, then ya everything is good, since the lakes will just replenish themselves, so no shortage.
Though the pros defeat the cons, rather be creating more rain instead of killing all life and having to bow down to people in Dubai laughing it up...
HYDROGEN CARS ARE THE SAFEST AND BEST WAY TO THE FUTURE!
** note** Hydrogen plants will be built, like they have in Tokyo, Japan.
