ISDC and SSP

Looks like the International Space Development Conference (ISDC) had quite a large program on Space Solar Power: http://www.nss.org/isdc/ISDC_2009_Program_Agenda_Web.pdf

According to the NSS Website (http://www.nss.org/about/):
The National Space Society (NSS) is an independent, educational, grassroots, non-profit organization dedicated to the creation of a spacefaring civilization. Founded as the National Space Institute (1974) and L5 Society (1975), which merged to form NSS in 1987 (see merger proclamation), NSS is widely acknowledged as the preeminent citizen's voice on space. NSS has over 12 thousand members (and more supporters) and over 50 chapters in the United States and around the world. The society also publishes Ad Astra magazine, an award-winning periodical chronicling the most important developments in space.

• NSS Vision: "People living and working in thriving communities beyond the Earth, and the use of the vast resources of space for the dramatic betterment of humanity."
• NSS Mission: "to promote social, economic, technological, and political change in order to expand civilization beyond Earth, to settle space and to use the resulting resources to build a hopeful and prosperous future for humanity."
• NSS Rationale – Why Our Mission is Important: Survival, Growth, Prosperity, and Curiosity
