I have noticed that most individuals rely on textbook knowledge which keeps them in a traditional rut. Most of our technologies today, including the space program are in a rut. The space elevator, a very simple concept, still has them stumped; but they will struggle through it, and perhaps it will be economical, like a freight train to where? There are other ways to exit the earth; Nasa and the rest of the world wake up---- It is not by brute force. Maybe, someday I will tell you what I discovered? Erich
