Beanstalk Ocularis
Space Elevators are the inspiration for this artwork. These are proposed for future, reusable, and affordable forms of space travel. Space Elevators use a taut, tethered rope which robotic vehicles use to transport people and objects into space. On one end, Earth’s gravity holds down the rope, the other end is held due to the centripetal force of its orbit. Here is a nice analogy on how it works from “How Stuff Works”:
To better understand the concept of a space elevator, think of the game tetherball in which a rope is attached at one end to a pole and at the other to a ball. In this analogy, the rope is the carbon nanotubes composite ribbon, the pole is the Earth and the ball is the counterweight. Now, imagine the ball is placed in perpetual spin around the pole, so fast that it keeps the rope taut. This is the general idea of the space elevator. The counterweight spins around the Earth, keeping the cable straight and allowing the robotic lifters to ride up and down the ribbon.
