Hydrogen Fuel Cells
Emissions = water vapor (much cleaner than gasoline, but still a greenhouse gas)
Few moving parts -almost no maintenance
More reliable and efficient than combustion
H produced by steam reforming natural gas
This is cleaner, but more costly than gas
and is not the most environmentally friendly process
300 miles on a single charge
Can fill up at any station, when/if
they build the costly infrastructure
5 min. to refill
Reduces our dependence on foreign oil
I Didn't find data on performance
25% power grid to motor efficiency
More expensive than gasoline
Technology is progressing
Current cost of production per vehicle:
$1,000,000
Estimated to be 20 years
until it's a feasible alternative to gasoline
Electric Car
No Emissions
Few moving parts -almost no maintenance
more reliable and efficient than combustion
Power plants (production of electricity is
cheaper and more efficient than gas
and H fuel cells and 100% clean
if electricity is produced by solar,
wind, hydro-electric power, etc...
Modern e-cars go 250 miles on a charge,
New auxiliary motor technology increases range to 600 miles
Can be plugged in at home - no trip to gas
stations station necessary!
Could build less costly refilling stations
5-7 hours to recharge
(5 seconds to plug in, leave overnight)
Reduces our dependence on foreign oil
0-60 mph in 4 seconds (Tesla
Roadster)
86% grid to motor efficiency
for production
Operates in all conditions
cheaper than gas - 2 cents per mile
Technology is progressing rapidly
An economy sedan
Can be built and sold at a profit for
$25,000 right now.

Actually, water vapor produced by using fuel cells does not affect global warming, because steam concentration always directly connected with saturation vapor pressure. Water vapor surplus in the atmosphere is condensed in any case.
Thank you for that information Stanislav.
