This might happen in France or Japan, but building nuclear power plant in
the US has enormous political hurtles to overcome. As energy costs increase
the out cry against nuclear should lessen...
Folks are just going to have to adjust! If someone doesn't like the recharge
time, then they can own a car with a gasoline engine. People who can't plan
or want instant gratification are going to be paying a premium.

You should get a copy of Skeptic magazine Vol.14 No.1 2008 and read the
article "The Hydrogen Economy" by Alice Friedemann. The article explains in
very stark terms what is wrong with hydrogen. The author states that
increasing the average overall fuel economy of vehicles would be the best
place to spend our money. Here is part of the conclusion section:
"The laws of physics mean the hydrogen economy will always be an energy
sink. Hydrogen's properties require you to spend more energy than you can
earn, because in order to get it you must overcome water's hydrogen-oxygen
bond, move heavy cars, prevent leaks and brittle metals, and transport
hydrogen to the destination. It doesn't matter if all of these problems are
solved, or how much money is spent. You will use more energy to create,
store, and transport hydrogen than you will ever get out of it."
