Space Elevator or Space Tower?
I asked this question "Japan is planning to be successful in making the first space elevator, can Japan realize this dream? Can space elevator really help us get around in space better than today's spacecraft propulsion technology?" on Quora and I got an answer with a very cool video which linked by a Quora user Bert Murray. Check the video out right after the break. I think you'll like it, and you could learn something about space too.
