Space Elevator: “50 Years after Everyone Stops Laughing” - Professor Christopher Impey

Initially developed by Arthur C. Clark, the concept of Space Elevator proves to be feasible sooner rather than later. This is an extract from the full-length lecture by Professor Christopher Impey, “Our Future Off Earth”: http://www.gresham.ac.uk/lectures-and-events/our-future-off-earth Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.

It has been suggested – 100 years after the completion of the first space elevator there will be more people living and working in outer space than on earth. The first space elevator is difficult to build.The second is much easier.The third, easier still etc.,until we have a ring of elevators around the planet.A trip to space will be as cheap as a train trip across the country.Colonizing the Moon and Mars will be affordable.Space tourism will be huge.Asteroid mining will be huge.And all of these industries will require lodging and related supply chain infrastructure for space side construction workers.A new space elevator concept will help to make us a true space faring civilization .
It has multiple tethers at its center ( for greatest strength ) and
fewer tethers as you move away from center ( for lesser amounts of mass ) . It is also in an elliptical geosynchronous orbit , so it appears to drop straight down from space , pick up a payload , and return to space , thus requiring a much smaller system than
an earth based space elevator. Let's get started.
What do you think? -
I hope I live long enough to witness this.
