Research Outline  

What do we get money for? It is to live. What do we spend money to live? If you survey the destination of money in detail, about 1/3 is spent on "food and water" and "heat and electricity (energy)". Self-sufficiency rather than purchasing these would reduce the carbon footprint and provide a lifeline guarantee. I propose this “Basic infrastructure type society". However, self-sustaining food and energy is a part of returning dependent life to a part of self-sustaining life, which is a big barrier for current people. Therefore, I proposed an eco-friendly lifestyle that could be entered even by a company employee in the city, and decided to live in Kawasaki town located next to Sendai city, which is rich in water resources, as a member of the local community. I practice self-sufficient food and energy as much as possible in Kawasaki town, and study on the technology for the university to self-sufficient energy. In Japan since long ago, food has been produced in the fields, wood has been used as firewood and charcoal as a heat source, and the flow of the river has been used as a source of power and electricity. However, it is necessary not only to imitate them, but to create utilization in a form adapted to modern technology. For example, biorefinery technology that produces chemical products using wood as a raw material, and utilization as energy source of hydrogen synthesized by electrolysis of water. I develop technologies to utilize the resources in Satoyama in a way that conforms to modern technology, and incorporate them into my own lifestyle to realize an environmentally friendly, safe and secure lifestyle.
