JAPANESE ADVANCE SPACE SOLAR
Scientists make strides in beaming solar power from space

“The idea of powering humanity by gathering an endless supply of solar energy from space has taken a huge step towards becoming a reality. Scientists working for JAXA, Japan's space administration, have announced a major breakthrough in wireless power transmission [accuracy by first converting the electrical signal to microwaves, then beaming them to a remote receiver, and finally converting them back into electrons. It is the first time scientists have been able to move electrons over any appreciable distance with such a high degree of accuracy]…The team reportedly beamed 1.8 kilowatts, enough juice to power an electric tea kettle, more than 50 meters to a small receiver without any wires. Up next: scaling the technology for use in tomorrow's orbital solar farms…[JAXA has been] working on this technology for years as part of the agency's SSPS (Space Solar Power Systems) effort…to harness the constant supply of solar energy directly from space using orbital solar farms, then beaming it back to Earth (and into a global grid) via microwave transmission…[The] orbital arrays would never have to deal with obscuring cloud cover or darkened nights…SSPS is still far closer to science fiction than science fact but JAXA's latest success clears one of the biggest and most fundamental hurdles…” click here for more
