The driving force behind Geothermal Technologies

About Us

Geothermal Technologies has been working tirelessly to develop innovative and sustainable solutions to fix the global energy crisis. Until now, attempts at widespread thermal harvesting using manufactured synthetic or Enhanced Geothermal Systems (EGS) have been decidedly unsuccessful as measured by forty years of effort and over one billion dollars of investment. Our mission is to furnish a means of providing access to a virtually limitless supply of clean, economically competitive geothermal energy.
