- What you say is true for the electric car technology that's currently on
- the road. While battery technology _has_ progressed overall, no battery
- technology has yet met the particular requirements for practical
- use in autos: long life (or cheap replacement cost), fast recharge,
- adequate range at highway speed, weight factor. This may change. The
- GM/Ford/Chrysler electric car battery consortium (with a subsidy from your
- federal gov) is currently pursuing some likely nickel-metal hydride battery
- technology from a Michigan firm that appears to meet many or all of
- the criteria. Time will tell.
-
- And incremental improvements continue. I read in the local rag's science
- page the other day that Hughes (a division of GM) had come up with
- a battery charging module that could put a full charge in a conventional
- electric car in about four hours -- twice as fast as normal. (Something about
- charging with a magnetic field rather than a direct connection.)
-
- Probably more real research has been done on electric cars in the past
- few years that in the 50 before that. The reason is the California
- anti--pollution law that mandates X percent (I think 2) of all cars sold
- in California be zero-polluters by 1997, going up to 5 percent a few
- years later. Everybody really rose to the challenge on this one (including
- the Japanese) because, I assume, California is such an important market.
