Harnessing geothermal and piezoelectric properties of stone for sustainable electricity generation

Year: 2025

Type: article

Abstract: This study introduces a novel hybrid system in which piezoelectric and geothermal properties are integrated into basalt and quartz stones to generate green electricity. The same is satisfied by the energy conversion capability, high thermal holding capacity, and the strong piezoelectricity of quartz. This study uses these mechanisms to develop a hybrid system generating constant, reliable, and sustainable energy. The results prove that the system can convert heat into electricity and expand to remote and off-grid areas. The work demonstrates stone heat retention, electric power generation, and integrated system efficiency to provide an accessible, low-cost, scalable alternative to available renewable energy systems. The results present a basis for realizing these properties as an abundant and reliable energy provider and offer a new alternative to traditional renewable technologies.
