FILE NAME DDI 2008 <BQ>    Your Name JAXA is developing SPS with success. Nilay Patel , 2/7/20 08, http://www.engadget.com/2008/02/07/japans-space-agency-planning-space-based-solar-power-arrays/ We've seen some pretty out there solar installations, but JAXA, the Japanese space agency, is about to get really far out with its latest project: a space-based solar array that beams power back to Earth . The agency is set to begin testing on the microwave power transmission system on February 20th, with an attempt to beam enough power over the 2.4GHz band to power a household heater at 50 meters (164 feet). That's certainly not the sort of large-scale sci-fi power system we were hoping for, but fret not -- if the tests are successful, JAXA's plan is to eventually launch a constellation of solar satellites, each beaming power to a 1.8-mile wide receiving station that'll produce 1 gigawatt of electricity and power 500,000 homes. 1

FILE NAME DDI 2008 <BQ>    Your Name JAXA is already working on SPS, years ahead of the US. Sarah Gingichashvili , 10/1/20 07, http://thefutureofthings.com/news/1013/generating-power-in-space.html JAXA researchers are planning on putting a prototype of the system in geosynchronous orbit approximately 36,000 km above the equator. A laser beam will be used to transfer the energy collected by the space-based solar panels to an intermediary or terrestrial power station, where its energy will be used to generate electricity or hydrogen . The Japanese scientists are using solar plates made from chromium, a ceramic material that absorbs the sunlight, and neodymium, which converts it into laser light. These solar panels demonstrated a 42% solar-to-laser energy conversion efficiency – an impressive figure that outperforms previous technology by a factor of four. Since this innovative system will be situated in space, it will be able to collect sunlight 24 hours a day, circumventing problems affecting ground-based solar energy systems , such as cloudy skies and darkness . The Sun’s energy is eight times greater outside Earth’s atmosphere. Therefore, it is estimated that a single satellite-mounted solar panel site will have a power output equivalent to a 1 GW nuclear power plant. 2

FILE NAME DDI 2008 <BQ>    Your Name Colanization is near impossible in our current technological state, lack of extraterrestial contact proves. Peter Ulmschneider, science author, 2/23/20 05, http://www.springerlink.com/content/12kd8xy4trn8apq1/ The questions “Why don’t we have contact with extraterrestrial intelligent life?” and “How will mankind evolve in the near future?” are intimately connected . Clearly, civilizations that are far behind our technological state would not be capable of communicating with us . But even societies more advanced than us would have difficulties in making contact, as radio waves or spacecraft take a long time to cross the huge distances in our galaxy . In addition, such advanced societies might no longer exist.
