Why take a rocket ship when you could take a space
elevator?
The futuristic space
transportation system, first proposed more than 100 years ago and later
popularized by science-fiction writer Arthur C. Clarke, could lead to
profoundly lower costs of launching anything into space, while increasing the
amount of cargo capacity – both material and human – for orbital trips, estimates
suggest.
A space elevator would
likely involve a cable – aka a tether or ribbon – stretching from the surface
of our planet into orbit. A recent BBC Future feature explained
the basic concept: An anchor and Earth’s gravity at the lower end, plus a
counterweight and centrifugal force at the top end, would keep the elevator’s
tether taut and stationary over a fixed, ground-based station. Robotic
“climbers” would then ascend the ribbon from the surface, through the
stratosphere and into space, potentially powered by lasers.
Among the major
challenges this massive engineering plan faces: creating long strands of an extremely
strong but lightweight material to construct the cable, as well figuring out how
to operate the system.
As a
manufacturer dedicated to
innovative design and manufacture of electronic
controls, Etratech understands the need for BIG ideas. And today’s innovative
thinkers, dreamers and doers are working to make this particular one a reality.
The International Space Elevator Consortium (ISEC), a consortium of organizations and
individuals worldwide promoting the development, construction and operation of
a space elevator, organized the 2012 Space Elevator Conference in
Seattle, Wash., in August. The annual conference engages
an international audience of scientists, engineers, inventors, educators,
entrepreneurs, enthusiasts and students in discussions of space elevator
development. The theme of this year’s conference: “Space Elevator Operations
and Maintenance.”
