Space Elevators

Arthur C. Clarke in his 1979 sci-fi novel, The Fountains of Paradise, builds a space elevator on Earth as a solution to the monetary and technical expense of Earth-based rockets.

A space elevator is a conceptual solution for a low-cost, low energy planet-to-space transportation system. The challenge to building the elevator is finding a material strong enough to withstand the immense compressional and tensional forces that with a counterweight balance, would be 44,490 miles long (71,600 km). Carbon nanotubes offer a possible solution but currently they are only strong enough to work on Mars or the moon.

This is not Clarke’s best novel, but he thoroughly explains the concept of a space elevator and a lot of the engineering problems that would need to be solved to build one. The solutions to all the problems are solved by the book’s protagonist, Dr. Vannevar Morgan, a thinly veiled character that likely refers to himself as Arthur C. Clarke when he is among friends.

As an aside, both within the book and as a reader, he spends 5-6 pages harping on his belief there is no God. Why he does so is a mystery since it adds nothing to his story and in the end, it is a pointless, garrulous, one-sided debate.
