ScienceAlert reports that Endurance Energy ran a generator using superheated fluid from Axial Seamount, an underwater volcano about 300 miles off Oregon, and generated more electricity than it consumed. The vent fluid reached 538 degrees Fahrenheit, while the turbine spun at about 26,000 revolutions per minute. During a short 8.7-second run, the median surplus was about 2 kilowatts, with a 16.5-kilowatt peak. The company’s results have not been peer reviewed; the video also covers a Tonga project planned for 2027 and remaining open questions.
