NSS just posted a link to a recent NRL report outlining the next steps needed to make space solar power a reality. We’ve linked to the report on our Space Solar Power page. The report concludes with six recommendations:

(1) Mature space solar’s functional technologies and develop advanced concepts, particularly for power beaming.

(2) Monitor and maintain parity with foreign developments to avoid technological surprise, and to reduce the chances of being faced with a breakout capability.

(3) Advance robotic in-space assembly and manufacturing technology. Investment in these fields could have spin-off dividends in areas as diverse as astronomy, intelligence, and space industrialization.

(4) Address regulatory hurdles, especially in the area of spectrum identification for power beaming.

(5) Track technological progress regularly in areas such as launcher reuse and satellite mass production.

(6) Strengthen relationships between defense and civilian agencies, as well as international partners.

Advances in Space Based Solar Power

Caltech researchers have come up with an innovative lightweight tile assembly that combines collection of solar energy, conversion to microwaves and transmission of the power via an antenna.  The modular design can be combined into an array enabling transmission of power where it is needed in space.  Combining these three functionalities into scalable modular units is a significant development toward realization of space based solar power.
