TechStartup tests tapping an underwater volcano for power

The first demonstration of a subsea geothermal power plant took place near the active Axial Seamount, nearly a mile beneath the northeastern Pacific. The three-week test produced net-positive electricity for less than 10 seconds, demonstrating technical feasibility. Seattle-based Endurance Energy aims to commercialize the technology.
