Episode 132 Space Elevator

Imagine a giant vertical railway stretching 100,000 km from the equator, somewhere in the Pacific, straight up into space. Instead of expensive, polluting rockets, the space elevator offers a smooth, slow electric ascent to Earth orbit. This “bridge to the stars” connects a floating Earth platform at 36,000 km to a massive counterweight located 64,000 km farther out. It is held taut by the Earth’s rotation.

Space travel is then transformed from a risky adventure into routine cargo shipping. Powered by revolutionary materials such as graphene and innovative laser beams, a space elevator offers a green, affordable gateway to the solar system. Making that a reality is the ambition of the International Space Consortium.

Rob Whielden and Adrian Nixon from the Nixene Journal talk about the final piece of the Space Elevator engineering puzzle – the ultra-strong material needed to make the tether. Both are experts on the unique properties of Graphene. In this interview, recorded at the University of Manchester’s Graphene Engineering and Innovations Centre, we discuss the ongoing journey of a Space Elevator from science fiction to an operational reality. The discussion includes

  • A 100,000 km tether connects Earth to a deep-space apex anchor.
  • Centrifugal force keeps the cable taut like a spinning bucket.
  • Graphene’s extreme tensile strength makes this massive engineering project possible.
  • Electric climbers move cargo affordably, bypassing inefficient, polluting chemical rockets.
  • Laser beams through atmospheric “windows” will likely power the climbers.
  • China aims to build a functioning space elevator by 2045.
