Earnest C. Watson Lecture by Professor Sergio Pellegrino, “Space Solar Power: A New Beginning.”
In 1968, Peter Glaser, the father of space solar power, envisaged kilometer-scale space systems comprising solar collectors and transmitting antennas that would beam power to the earth from geostationary orbit, but that dream has remained elusive. Until now. In his talk, Sergio Pellegrino will discuss the Caltech Space Solar Power Project’s pursuit to conceive, design, and demonstrate a scalable vision for a constellation of ultralight, modular spacecraft that collect sunlight, transform it into electrical power, and wirelessly beam that electricity to the earth. The basic module of this future solar power system is a giant coilable structure that elastically deploys after launch into orbit, and is made of paper-thin materials of high stiffness.
Sergio Pellegrino is the Joyce and Kent Kressa Professor of Aerospace and Civil Engineering at Caltech in the Division of Engineering and Applied Science; Jet Propulsion Laboratory Senior Research Scientist; and Co-Director of the Space-Based Solar Power Project.
