The electricity has to come from some where and about 2/3rds to 3/4
comes from coal fired plants. These plants put huge amounts of CO2,
Mercury, and Sulphur into the air along with lots of particulate
matter. That means the so called clean electric car would probably
cause far more pollution than what's on the road now.

Both Hydrogen and Electric cars which are touted as being so clean
only move the source of pollution from the vehicle to the power
generation plant. Hydrogen takes even more energy to produce so it is
even less efficient.

Prof. Heywood at MIT Sloan Labs has co-authored a few papers on this sort of
topic that you can find somewhere on the MIT website. There is a lot of hype
and nonsense printed out there, but John has always seemed to be pretty
level headed to me.

Aviation content - if it wasn't for his glasses (about 3/8 inch thick) John
Heywood would look kinda like Bob Hoover.
