Designers Ostap Rudakevych and Masayuki Sono have unveiled a design for a skyscraper that would hang from an orbiting asteroid:
Clouds Architecture Office has unveiled plans for a futuristic skyscraper dubbed the "Analemma Tower." The building would hover majestically above the ground because it would be attached -- wait for it -- to an actual asteroid, in space, that is forcibly put into orbit around the earth.
If that's not enough to digest, consider that your exact address in this pendulous pad could be anywhere on Earth. The tower will be suspended via high-strength cabling from an asteroid and placed in "eccentric geosynchronous orbit". In other words, it would be always moving -- residents and visitors would take a daily journey between the northern and southern hemispheres with a prolonged visit over a main "home" point like New York City or Dubai (it's always New York City or Dubai, isn't it?)
[...] Analemma Tower's designer Ostap Rudakevych told CNN that the tower could be made of durable and lightweight materials such as carbon fiber and aluminum. Advances in cable engineering would be needed to achieve the cable strength required to support the structure. Power would come from space based solar panels that have a constant exposure to sunlight. Water for the tower will be captured from clouds and rainwater and maintained in a semi-closed loop system.
As proposed the top of the tower sits at 32,000m and would be expected to reach speeds of 300mph as it travels through the sky.
