Due to the disastrous accident at Fukushima Dai-ichi Nuclear Power Plant caused by the 3.11 Tōhoku Earthquake and tsunami, energy reform was needed to avoide dependence on nuclear power. The author suggests that we can tackle this energy shortage with Solar Power Satellite (SPS) construction. SPS is a satellite that can deliver the electricity generated from the solar cell panel to the earth by converting it into microwave. The field of SPS is the key tool with high expectation for the survival of mankind in the coming future, where Japan’s first-class techniques can lead the whole world. A pioneer who has spent most of his life on both domestic and international projects on SPS research, the author illustrates its possibility and hopeful future. It is a must-read, especially for those in disaster-hit Japan, as the nation attempts to stand up once again and take a step forward in space.
