Aiming for Local Production and Consumption of Energy

Immediately after the Great East Japan Earthquake, I arrived at the university and started research on renewable energy that is resistant to natural disasters. For 10 years, I continued my research with my dear students in areas where other researchers have not done much. Among them, I would like to introduce three technologies that I have a strong feeling for. We have developed a transparent solar cell that converts ultraviolet rays into electric power, including its formation technology, and achieved the world's highest level of efficiency. It was possible to show that wind power generation with a diffuser using the wind lens effect can generate power even in weak winds. Furthermore, the soil microbial fuel cell originating from microorganisms has achieved 10 times the conventional power generation by introducing the novel porous body, which is our invention, and is close to practical use. This area has long daylight hours due to the coast of the Seto Inland Sea, and although it is weak, the wind always blows, and there are many lakes and rice fields. We would like to receive natural energy from them and convert it into electric power, which will lead to the realization of local production for local consumption of energy.
