Space-Based Solar Power | Department of Energy

Mar 06, 2014· To make this possible, the satellite’s solar power beaming system employs a diode-pumped alkali laser. First demonstrated at LLNL in 2002 -- and currently still under development there -- this laser would be about the size of a kitchen table, and powerful enough to beam power to Earth at an extremely high efficiency, over 50 percent.

19 Advantages and Disadvantages of Space Exploration

One of the reasons why fictional universes like those in Star Wars or Star Trek are popular is because they show us a reality where hope is possible anywhere. In the former, space exploration leads to an independent spirit where the fate of one's culture and identity are at risk of being overrun by a zealous government. In the latter, humanity overcomes its core problems of conflict, hunger
