Space Solar Rectifying Antenna On Earth, Corey Bergsrud, Timothy Dito, Matthew Anderson, Matthew Clausing, Chase Freidig

Online Journal of Space Communication

The realization of solar power from space is becoming increasingly closer as a solution to solving the continued growth in energy demand. Space based solar power is also being perceived as an alternative solution for non-renewable energy resources. Future solar power satellites will be positioned in orbit around the Earth where they will collect solar radiation. That radiation will be transformed into a microwave energy beam that is targeted to a receiving rectifying antenna or “rectenna” located on Earth’s surface. The received microwave energy will be converted into direct current electricity.

This presentation focuses on the microwave patch antennas used …

Space Solar Power With Sunsynchronous Orbits, Michael Blohm, Alan Guy, Kyle Perkins, Adam Roades, Samantha Williams

Online Journal of Space Communication

The basic problem being addressed here is the high initial cost of solar power satellite (SPS) systems. The cost is higher for GEO orbits because of the large solar array and transmitter sizes required from that distance, and the expense of lifting such a mass into the higher orbits. Aperture size is proportional to the distance the power is beamed; thus transmitter apertures can be smaller when nearer to Earth.

Decreasing the distance energy must be beamed through space means that the powersat need not be so large, or as expensive. Implementation of sunsynchronous sunsats will likely be a more …

Solar Sails: Towards An Early Profitable Powersat, Jake Coggiano, John Dees, Ryan Heitkemper, Lauren Valko

Online Journal of Space Communication

Successful development of space solar power would provide vast quantities of clean electrical energy for the next few billion years. Such a prize is worth considerable effort and risk. However, the technical difficulties and the huge scale of proposed systems, requiring enormous up front costs and long development times, have prevented SSP from making much progress.

If a way could be found to field a small SSP system profitably, even if limited to niche markets, operational progress could be made with relatively small investments over short time scales. This visualization explores the concept of a “thin-film heliogyro” – a solar …
