The cost of the car will be another story,

LOL! And you can also figure several thousand $$$ for the "home electrolyzer"
Not to mention a horrendous electric bill to run the blasted thing.
Heck, Kalifornia can't generate enough electricity in its grid as it is,
And everybody there is supposed to start generating hydrogen for their cars???
ROTFLMAO!!!
What a bonehead idea this "hydrogen economy" is!!!

[the bottle let me down]

Not to mention a horrendous electric bill to run the blasted thing.

I predict that state regulators will force all of us to subsidize the electricity used to run these things.

Where, perchance, is the electricity for all of these wonder home machines to come from? Electricity, mostly produced by burning coal, therby putting more pollutants and carbon dioxide into the atmosphere than burning gasoline does now. If the electrolizers are used to separate the hydrogen in hydrocarbon fuels from the carbon, you lose at least half of the energy in the feedstock. Further, the resulting carbon will need to be disposed of, possibly as carbon dioxide, thereby frustrating the greenies.

All of this hydrogen technology talk is pie-in-the-sky wishful thinking. Hydrogen must be extracted from either a hydrocarbon or water, and more energy is used extracting it than comes from actually using it. Further, if the feedstock is a hydrocarbon, then you lose the energy in the carbon and still have to disposse of the carbon. That leaves water as the feedstock, and the need to expend prodigious amounts of electricity, mostly produced by burning hydrocarbons, to obtain the hydrogen.

Dude, it will come from all the solar panels and windmills we are going to put in our backyards.

If they can build a home electolyser, they can build a comercial version for a "gas" station as well. That would have the advantage of not requiring all the infrastructure to transport the hydrogen itself. It would also mean the stations would not need to store large amounts of hyrdogen, as they must now store large amounts of gasoline. Of course gas stations might need a mini electrical substation of their own. :)
