I can't follow the cost issues on those PEM fuel cells. They've been used in
military and space applications since the mid-'60s. One time I hear tens of
thousands of dollars, and the next time they're building a scooter that's
"just a bit more expensive" than the gas-powered equivalent. Maybe that's
why they're saying production starts in 2015 -- they're trying to get the
cost down.

Mercedes-Benz F800 pairs hydrogen fuel cell and plug-in hybrid

That means the F800 Style can travel for 18 miles on electric
power alone after being plugged in overnight -- and when it runs
out of juice it can cruise for another 375 miles on hydrogen. The
result: no emissions.

-----------------
Anyone know if it is cost/emissions to burn hydrogen rather than
gasoline/diesel when the current processes to generate the
hydrogen is considered? Water electrolysis using wind/tide/wave
generated power would be emissions effective but the cost?

Still no magic [carpet] solution...
