In January 2024, Sakurajima Volcano in Japan erupted, causing great distress to nearby residents. Besides, Japan has mountainous areas, a large population, and a serious shortage of building land, and the residential problem needs to be solved urgently. This project tackles these issues by extracting magma from the central tower, using it to generate electricity, capturing greenhouse gases for fuel, and utilizing volcanic rock for 3D printed homes. This plan mitigates environmental impact, addresses housing shortages, and enhances energy sustainability in Japan.
