Surely that Arthur C Clarke idea of the Space Elevator is something mind-blowingly many years away from reality? Isn't it? Believe it or not, a body called The Japan Space Elevator Association has just published plans how to build one.
Director of the association is the professor of precision machinery at
Space elevators were always mentioned as the killer app for carbon nanotubes, when carbon nanotubes were first popularised.
I had assumed that it was pretty nigh impossible to lay a couple of CNTs end to end with any hope of them sticking together but now, it seems, modern CNTs need only to get 4X stronger to be able to build a space elevator.
And getting 4X stronger shouldn't be a problem, because CNTs have been getting stronger at a rate of 100X every five years.
The project will cost $9 billion, says the association, and will use 62,000 miles of cable.
It seems a good wheeze for
While the
Once
