> I disagree.  In the year 2050, the major source of fuel will be
hydrogen.

nah. you're all wrong. it'll be alcohol. too easy to make ... can make
it from garbage.
the problems associated with it are fixable ...using stainless steel
pipes and such (even glass would work), and it's pumpable using the
equipment at the gas stations already ... hydrogen would take way too
much money and time to change over.

and remember ...we're talking about letting loose a highly flammable
explosive gas (hydrogen) on the public of this country ... the same
public who sits in front of televisions and watches "Survivor"? the
same public that has never learned out to drive automobiles safely?

besides, with alcohol, we'd get rid of a few more morons when they
tried to drink their auto fuel. :)

but the thing that i truly see happening is hybrid cars ... at this
moment, i can't see anything else that's feasible ... a true hybrid
will have a small alcohol engine, specifically designed to operate at
a narrow range of rpm to generate electrical power to run the electric
motors of the automobile. in other words, right back to the original
design of Ferdinand Porsche. and his version had four-wheel drive (the
electric motors were built into each wheel, like a large earth-mover).
all of this is possible right now ... just not fashionable. anyway,
the hybrid design can solve a lot of emission problems as well as
using less fuel to go the same distance ... figure 300 miles on about
5 gallons of fuel.

them's my predictions and i'm sticking with 'em.

unca Nostradamus :)
