In a previous post, “Our Energy Future: Solar Power,” I mentioned a mini-series the Discovery Channel aired in 2007 called 2057, in which physicists and futurists discussed current developments that will possibly mold the next 50 years of human civilization. Aside from some bland acting, it was very informative. 😉
In the episode 2057: The World, a space elevator was discussed. If you think that is what it sounds like…you’re right. An elevator cable (made of an extremely strong material) is descended from a space station in orbit around the planet to a station on the surface of the Earth. The promise: space travel becomes so affordable = space tourism and exploration is possible for the average person.
