Place a geostationary microwave station in orbit and broadcast to a set of Bloom Boxes placed around the countryside. If one location is clouded over, broadcast to another location. These microwaves could also power a spacecraft (space elevator).
Everything could be solar powered. Spacecraft could be launched from airports such as Chicago's O Hare. Such stations could be set up on our Moon/Mars/beyond.....This system could be tested on the ISS. Use Ion engines on the spacecraft.
Note: Look for Bloom Box on the web. The BBs are chemicaly treated sand.
The BBs can be used in homes as they come in all sizes.
Google is testing the system at its headquarters (as shown on a recent '60 Minutes' episode).
