That's pretty incredible, and here I though the Wankel was a fairly unique engine. Not directly related but learning about the diesel-electric locomotives and the transition from PWM DC to 3-phase VFD with the traction improvements(I seem to recall they doubled available traction but would have to check my sources[1]) was also something that caught me by surprise. All these EVs out there now owe a lot to the work that happened back in that industry. Edit: found the one of the sources I remember reading.
