wireless power transmission
Wireless power transmission is the transmission of electrical power over long distances without the use of wires connecting the two locations.
Although this technology has some purely planetbound uses, it is a key technology for space-based solar power.
- 2008-09-09 Space-Based Solar Power Breakthrough to Be Announced: "The project demonstrated wireless power transmission between two Hawaiian islands 148 kilometers apart, more than the distance from the surface of Earth to the boundary of space." This type of technology has been demonstrated before (as early as the 1980s), but presumably over far shorter distances.
