Ah...Â* Someone previously mentioned getting about 50% back going down a
hill from what he used going up.Â* I'm sure that's variable, too.

I think these electric cars are terrific and, for a lot of folks, work
out great.Â* But, for me and others who live out in the wilderness, they
just can't /_yet_/ compete with gasoline or diesel over the spectrum of
use.Â* There will come a day, however, when the state of the art will
announce the demise of internal combustion engines.Â* I hope I'm around
to see it.

Regenerative braking does work but, like other things in life, there's

Yes,I understand that (Chemistry degree, so allegedly I have/had a decent
grasp on basic physics). So, I understand that you don't get back all the
energy spent in getting higher when you come down again.

What I don't understand is what proportion of that energy you get back,
given the current state of automotive engineering. This is why I'm asking
questions about it.
