Default Can Aircraft Be Far Behind

There is little doubt, that electric drive vehicles will supplant

If trains were battery powered, like the electric cars we are talking
about, you might have a valid comparison. Batteries are still the weak
point. While they are improving they are still a very long way from the
energy density fond in gas and diesel. Even when you take into account
the conversion efficiencies.

Also did you notice the base price for that Tesla Motors car? $92,000!!
It's just a guess, but I would bet that outside the battery powered
part of it, it is equivalent to at best a $45,000 gas car. When you
calculate that at $5/gal in a 25 mpg car, for gas over 100,000 miles,
costs $20,000. That is a huge price to pay just to have an electric car
even if the electricity to recharge it were free.


Unfortunately, it seems that most innovative, breakthrough technology
seems to occur outside the US these days:
