What advances in batteries have we made in the last 100 years?

You put energy in and you take energy out.

That's what batteries do of course - store energy for use at a later
time. How do you propose to advance that?

Energy stored per pound has advanced a lot. If you don't believe
that, take a look at the latest generation of cordless tools or laptop
computers.

Being able to store energy at a reasonable cost and weight is key to
making electric vehicles practical. Although the Volt is not yet the
ideal electric car, it is a step forward. Internal combustion
engines started off slowly also. Take a look at the automotive
engines of 100 years ago vs what we have today.

The Tesla is quite the technological car though!

It has a battery and electric motors.

So? Your car still has an internal combustion engine. Is it the same as
a Model A?

Yes. The internal combustion engine has not changed much in 100 years
either.

Bull****! That's a very ignorant statement!

Specifically what has changed?

Metals used, fuel delivery systems, advances in combustion technology,
advances in exhaust technology, much better efficiency, electronics for
combustion, fuel efficiency, engine control, emissions, and on and on...

Those are all just improvements on something that already existed.

Well, I guess the same could be said of computing then. Same as it was
in 1850 because DC current works the same now as it did then!!! Makes
just as much sense as your posit.

You could go back to the abacus
