The author calls Mitsubishi Heavy Industries' J-Class gas turbine from the Takasago Machinery Works Japan's crown jewel in the AI power stack — extremely advanced and efficient, with orders booked out for years, competing mainly with Siemens and GE. Spec sheet: hydrogen-ready (co-fires 30% hydrogen, capable of 100%), world-leading efficiency above 64%, 65% lower carbon emissions than coal plants, and over 1.7 million operating hours across the J-Series fleet. Part of a thread on East Asia's AI-electrostack.
