Beaming Clean Energy From Space
Once considered science fiction, technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of Caltech researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed—including to places that currently have no access to reliable power. "This is an extraordinary and unprecedented project," says Harry Atwater, Otis Booth Leadership Chair, Division of Engineering and Applied Science; Howard Hughes Professor of Applied Physics and Materials Science; Director, Liquid Sunlight Alliance. "It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world." [Caltech story]
Sergio Pellegrino's Paper Wins the IASS Tsuboi Award
The paper "Mapping Two-Way Grids on to Free-Form Surfaces" by Sergio Pellegrino, Professor of Aeronautics and Civil Engineering, and co-authors Pete Winslow and Shrikant Sharma has been selected as the winner of the IASS Tsuboi Award in the category of the most outstanding paper in the Proceedings of the 2007 IASS Symposium. Pellegrino has also received a best paper recognition for "Computation of Partially Inflated Shapes of Stratospheric Balloon Structures" with co-author Xiaowei Deng. This work has has been selected as the best paper by the ASME Aerospace Structures and Materials Technical Committee. The award will be presented at the 50th AIAA SDSM conference.
