Bluesky: @kbrigham.bsky.social Katie Brigham · 22d ago · 6 ♥ for a grand total of 8.7 seconds, a startup produced net power from a subsea geothermal power plant. it could be the dawn of a new energy era! OR an indicator that this is gonna be practically impossible to operate economically for any real length of time. who knows!
