Those are still the characteristics of virtually all the world's electric vehicles, which are powered by cumbersome battery systems. The traditional lead-and-acid batteries require 100 times the weight and 30 times the space of conventional gasoline tanks to push even the lightest cars a fraction of the distance -- less than 100 miles at 25 m.p.h. Nickel-cadmium batteries provide 50% more power but at eight times the price (around $30,000, replaceable every two or three years). Sodium-sulphur batteries offer three times the energy but run both hot (at temperatures of 600 degrees F) and volatile...
