Sun Star Concept: Constellation of relatively small satellites at Iqw to middle altitude transmits power via free electron laser to very small ground sites. Key Features: heliogyro solar array thin film amorphous 6-10 meter diameter ground receivers Suggestor/Source: J. George, NASA/LeRC Discussion Each launch of a reusable launch vehicle delivers one complete satellite to the destination orbit, where a simple self-deployment sequence places the FEL-based power transmitter in operation, delivering a few kW per day to remote oflf-grid locations. Multiple satellites could deliver a few MW per day to one site. Power and revenue are thus generated from the first launch, and capacity increases can be matched to user demand, according to the number and locations of satellites deployed. Advantages Disadvantages Some modularity Serves small markets by design Interesting for space power applications FEL technical development required Not an all-weather system Laser hazards at surface
