    While I agree there is more room for battery and related technologies like ultra-capacitors to grow, batteries represent a far more mature technology than did computers in the 1980s.  1980 was a bit more than 30 years removed from the first all-electronic Von Neumann computer, and the first laboratory tests of a standalone transistor. It was just over twenty years after the first laboratory integrated circuit,   and about ten years after the first 4-bit micro-processor was created.

    By contrast, the first four-wheel electric car was built 125 years ago, and two-wheel electric cycles go back 20 years before that.

    Add in the fact that many different kinds of batteries have been used in many different applications over that period and you can see that the comparison is not apt.

      They might give an order of magnitude improvement, which would scale the Chevy Volt 40 mile pack to 400 miles.  Don't give up hope.  When people stop trying or think there's no point, that's what keeps us stuck with 19th century energy sources.

      But again, pure electric might not be needed.  My next car probably will be a Chevy Volt.  I won't use a drop of gasoline for 95% of my driving, but when I go to see my parents 180 miles away, then the gas engine is there.  And at $4 a gallon, break even time is 3-4 years.  Not bad.

      But since the goal is C02 reduction, going hybrid-electric will cut my C02 95%.  If every car in America was like the Volt and got the first 40 miles/day C02 free, we probably wouldn't have a C02 problem.

        The beauty of unexpected breakthroughs is that they are unexpected.

        It's easy to forget, however, just how much energy is required to propel a car, and what that means in terms of batteries.

        You're right about the volt, though.
        And -- in europe, they've got some diesel cars that hit 80mpg.

        Imagine an inline diesel hybrid -- junior size version of a diesel locomotive.

        Cutting those numbers is a good thing, even if the way we do it isn't quite what we had pictured.
