OT <<. I'd LOVE to have an electric car. But the cost of entry is way too high.>>

Me too, on both counts. 30 years ago, when I was almost a teenager, I was at my uncle's house in Florida. They had been given an experimental electric vehicle to use for the summer. It was a four passenger acid battery vehicle that could run for about an hour before needing to be recharged -- plugged in. As I recall, it topped out at around 30 m.p.h. They used it primarily to scoot around the small Florida island where they had their beach house. It was one of the first "vehicles" that I was ever allowed to drive on a real road. We quickly learned the relationship of time v. distance v. battery life. Pushing it a half-mile in the Florida heat was not much fun.

I have always had a kind of nostalgic soft-spot for electric vehicles since then.

Of course, the current price combined with my 30 mile, 45-90 minute, one-way daily commute makes it impractical.

Someday it will be cost efficient, but only because the relative cost of operating a gasoline powered vehicle will have climbed to the point of making it so. Perhaps by then I won't care about the cost and can add to the demand (my way of getting this post somewhat on topic).

I have never fully understood why alternators (generators) could not be used on electric vehicles to recharge to a substantial extent on the fly. I understand why they cannot recharge 100+ percent (some crazy law of physics), but have wondered why efficient generators could not or would not significantly lengthen useful battery life between power-off charges. I suspect that the answer is probably rooted in some very basic physics principal; otherwise, we would have efficient, low priced electric vehicles. I suppose that is why I chose law and not engineering.
