Abstract
One of the unrealized potential uses of space systems that has been discussed and examined for nearly five decades is the tantalizing idea of creating solar power satellite, or what is most commonly now called space-based solar power (SBSP). The theory is that it would be possible to create such a system at geosynchronous orbit or perhaps at a suitable Lagrangian point that would be capable of beaming clean energy back to Earth on a 24 hours a day 365 days a week basis. This energy would be sent down to Earth using a suitable radio frequency or laser transmissions that could then be converted to electrical power using diodes placed within dipole antenna receivers. This energy could then be sent to locations where energy is most needed. Countries without large energy reserves, such as China and Japan, have accordingly been among those nations that have pursued some of the most active research programs in this area [1].
