A further source of comfort to this sceptic is the regular newsletters that he receives from The Liftport Group, a consortium of private companies whose object is to built the first space elevator (a project that finally became feasible last year when the announcement of a a viable process for the construction of carbon nanotube ribbon was announced). The date that they have set is April 12, 2018.
The elevator—which would, in turn, allow the even easier and cheaper construction of successive elevators—is important; it would open up the whole of the solar system and beyond to us since spacecraft would no longer need to escape the Earth's gravity well (wherein most of the energy is used). It would allow us new resources and, more importantly, ensure our survival when, as it will, that ultimate meteorite strike happens.
Mankind may not be, in the words of a commentor at Robert's, "as bright as it thinks it is" but I believe that it is quite bright enough to solve those problems which need to be solved.
So there you have it. The proof is in the pudding. Or mail list. And a new slogan is coined for the Dawn of the 21st Century:
Liftport - a Source of Comfort
God love the Scot turn of the phrase.
