The Vision
• The Development of “Commercial Space” is much more than just “Space Commerce”.
• NASA Ames Director Pete Worden has said we are pursuing the destiny of humankind to develop a “solar system-based society”. Eric Burgess has said it is vision of what humanity will be a billion years from now.

Commercial Space Today
• Total Revenues from Commercial Space are about $230 Billion-almost a Quarter of a Trillion $$.
• This is dominated by satellite communications (Direct Broadcast, Mobile & Fixed Services ($130 billion/yr.)
• Military space, launch services & ground stations
• Space Navigation ($8 billion/yr and growing)
• Remote sensing & Earth Observation ($2 billion/yr)
• Space tourism (today in the noise level)
• Solar Power (still in infancy)

Solar Power Satellites
• Evolved a great deal from massive platforms in space to much simpler concepts.
• Most concepts now based on film-like concentrators.
• Solaren plans to over commercial product to electric power systems as of 2016
• Japan, Canada and now even Indonesia plan to deploy systems within 5 to 6 years.

Solaren Concept-3 Components
• 1. Large Scale Film Reflector or concentrator • 2. High Performance Photo Voltaic Solar Cells• 3. Transmitter of Energy to Earth as RF
Transmission back to huge receiving antenna• Issues: (i) Cost efficiency (ii) receiver site
design and potential reflectivity back to space (i.e. bad for comsats), (iii) Registration and International Coordination.

Prospects For The Future
• Space Transportation-Space Adventures-Commercial Space Stations. (500 people have gone into space today. Thousands within the next few years starting in 2011?)
• Solar Power Satellites The sun provides us with 10,000 times more energy than we are currently using . Huge potential for the future.
