I agree with you about the coming of electric. A researcher at Purdue (//www.purdue.edu Research Park News) has just completed experimental battery charging by draining and replacing the electrolyte. He can charge a car battery in the same time as a gas fill-up.
Yup, noted expert Lance Armstrong proved out the concept of replacing his electrolyte to gain recharge quickly. They always talk about steroids, but he beat detection mostly by getting fresh blood transfussions.
