U.S.-Japan Joint Seminar: Space Solar Power Systems

该奖项支持美国科学家参加将于2003年7月3日至4日在日本京都举行的美日空间太阳能系统联合研讨会。联合组织者是加州大学洛杉矶分校的伊藤达夫教授和日本京都大学的松本博教授。这次会议将汇集来自美国和日本的研究科学家，这两个国家在这一科学领域取得了重要和令人兴奋的进展。空间太阳能卫星(SSPS)项目是一项可再生能源技术，通过收集太空中的太阳能，将其能量转化为高功率微波束，然后将其定向到地球表面。在地面上，这种定向微波波束被整流成直流功率，用于输送、存储和其他用途。日本还在工业和大学之间创建了太阳能卫星项目。他们还一直在研究SSPS的各个方面，如太阳能电池、大型空间结构、微波产生和传输、地面整流、机器人、电力推进、姿态控制、系统设计和操作、环境影响和经济影响。这些研究要素既包括实际实施问题，也包括科学基础研究问题。联合组织者在该领域拥有互补的科学专业知识。这使他们能够评估并吸引最好的科学家参与。发展可持续的可再生能源供应显然是美国和日本都有非常强烈的共同利益的领域。两国都对开发石油和核能的替代品感兴趣。此外，功率传输将需要就两国之间频谱空间的使用达成一些国际协议，以使其成为可能。研讨会组织者特别努力让研究生既作为参与者又作为观察员。与该领域的日本专家交换想法和数据将使美国参与者能够推进他们自己的工作，并将为未来的合作项目奠定基础。研讨会结束后，组织者计划在加州大学洛杉矶分校的微波电子实验室网页上提供会议记录。

03150990ItohThis award supports the participation of American scientists in a U.S.-Japan joint seminar on space solar power systems to be held in Kyoto, Japan from July 3-4, 2003. The co-organizers are Professor Tatsuo Itoh at the University of California, Los Angeles and Professor Hiroshi Matsumoto at Kyoto University in Japan. The meeting will bring together research scientists from the U.S. and Japan, two countries where important and exciting progress in this area of science is being undertaken. The Space Solar Power Satellite (SSPS) project is a technology for renewable sources of energy obtained by collecting the solar power in space, transforming its energy into a high power microwave beam that is then directed to the surface of the earth. On the ground this directed microwave beam is rectified into DC power for delivery, storage and other use. Japan has also created Solar Power Satellite projects both among industries and universities. They have also been looking into various aspects of the SSPS, such as solar cells, large scale space structures, microwave generation and transmission, ground based rectennas, robotics, electrical propulsion, attitude control, system design and operations, environmental effects, and economic impacts. These study elements include both practical implementation issues and scientific basic research issues. The co-organizers have complementary scientific expertise in the field. This enables them to evaluate and attract the best scientists to participate. The development of sustainable, renewable energy supplies is an area where both the U.S. and Japan clearly have a very strong common interest. Both countries are interested in developing alternatives to oil and nuclear power. In addition, power beaming will require some international agreements on the use of spectrum space between the countries to make it possible. The seminar organizers have made a special effort to involve graduate students as both participants and observers. The exchange of ideas and data with Japanese experts in the field will enable U.S. participants to advance their own work, and will set the stage for future collaborative projects. Following the seminar the organizers plan to provide conference proceedings on their UCLA Microwave Electronics Laboratory Web page.
