NASA has developed several concepts for a space-based solar power station. This one is called the Sun Tower and would involve an array of inflatable circular solar concentrators. Even before any energy is produced, it is estimated to cost at least $12 billion.

(CNN) — In space there’s no atmosphere, it’s never cloudy, and in geosynchronous orbits it’s never night: a perfect place for a solar power station to harvest uninterrupted power 24 hours a day, 365 days a year.

The concept has been around since the 1940s when science fiction writer Isaac Asimov posited the idea of a robot-manned space station that delivered energy to Earth via microwaves.

Today, the idea is less science fiction than a steadily advancing reality.
