Endurance Energy tests undersea geothermal plant off Oregon, drills 52-foot well into 500°F heat and briefly generates net-positive power

Endurance Energy tested an undersea geothermal system off Oregon, drilling a 52-foot well into 500°F heat and briefly generating net-positive electricity before a cable failure halted the experiment; the Seattle startup, founded by former SpaceX engineer Andrew Redd, aims to build a network of undersea power plants to provide baseload clean energy and has raised $63 million.
