But the pollution is limited to specific places (gydrogen production
plants), and not spread wherever the fuel is "used". (for cars, all
over the world). To filter a single production plant to reduce
pollutants in the atmosphere is more simple than apply filter to all
machines all over the world. And, anyway, pollution would be located
away from cities.

Never made "organized" calculations, sorry. Just made some when reading
about the subject. Anyway, it was just a provocation. I don't know who
you are, and you don't know who am I. And, all I consider all I read
and write here as personal considerations, where not else specified as
"qualified informations".

You can actually buy a working fuel cell, with different choices about
what fuel to use (hydrogen, methanol, methane...).
Actually, you can buy a flight on SpaceShipOne, the first private
spaceship.

Well, you also "believe" your numbers, isn't it? Einstein believed his
numbers, but Hawking and others are demonstrating that they were wrong.

Don't have much time, now, I'm at work...sorry...

Not yet, maybe. And I never said that hydrogen fuel cells are a
tomorrow's technology.

Never done this. As said, if you ask "what is the lowest pollutant
machine?", what is the answer? Or, "what is the more noisy between an
electric fuel cell powered car and an internal combustion car?"?

Not from cities. It comes from production facilities where power can be
obtained in the most efficient way possible. A turbine in a power plant
is more efficient than wany personal car. It will work at the more
efficient regime, constantly, when normal cars rarely run at the most
efficient rate. And, as said before, pollution will be generated from
the production plant, a relatively well known and manageable source of
pollution, instead than from milions of cars all over the world...

Not nice to define groups-beta.google.com as a "stupid
newsreader"...what's the problem?
