Architecture firm: Floating skyscraper would hang from asteroid

WASHINGTON, D.C. -- A New York architecture firm has unveiled their plans for a floating, solar-powered skyscraper that would hang from an asteroid and use water collected from clouds.

They call the conceptual building Analemma Tower, and propose that it would hang from a high strength cable attached to an asteroid in orbit 50,000 km above the earth.

The skyscraper would be constantly moving in orbit, with prolonged visits over a home base city like New York City or Dubai.

The firm, Clouds Architecture Office, says that the idea is of wrangling an asteroid is not too out of this world -- they point to NASA's successful 2015 comet landing as an inspiration.
