How pratical are hydrogen fuel cell vechicles?

If a majority of our automobiles were replaced with vehicles which operate on hydrogen powered fuel cells, how could massive amounts of hydrogen be stored safely for refueling? How safe are these cars when the fuel tank ruptures due to collision compared to current gasoline/diesel ones currently in use? How many miles will the vehicles be able to go before refueling?

How much Hydrogen is needed to react in a Hydrogen fuel cell?

So, my question is if anyone knows or can point me to a link is, how much compressed hydrogen is needed to react with a fuel cell to produce enough electrical power to at least equal the amount of drivable distance as a modern gasoline powered car? I can understand that no one may know this as a result of industry secrets and what not, but ill take anything.

Why not electric motors to power airplanes?

I caught part of a show regarding non-conventional automobile fuels, including fuel cells, high powered electric cars (very fast and quiet), hydrogen, and very high mileage/high powered vehicles (e.g. 140 MPG with lots of horses). After listening to this for a few minutes, it seems like electric motors have something to offer to aviation. Thanks

When will someone make a decent EV?

I drive only 5-20 miles a day, but part of that is on the highway at 70 mph. I need an electric car that can do decent speed, but I don't have 0,000 for a Tesla.
When are the major manufacturers going to sever this incestuous relationship they have with the oil companies and start selling what folks like me need?
I'll probably always have a fueled vehicle – nitrogen gas or hydrogen or fuel cell or biodiesel or even (gasp) gasoline – for long distance trips and hauling the family.
But for my daily drives to work and back, I don't need capacity, or even much range, just reliability and speed. And I don't seem to be alone – there are a lot of drivers on the road with me who are alone in their cars.
Does anyone have an idea when we might see a real "plug-in" car?

Does no one read the question? "Someday" is no answer, and neither is "no demand" and neither is "try a search." If anyone has an idea, please let me know, but if you haven't a clue, keep your comments, please.
