Yawn.
Electric machinery that makes me smile? How about a GE 6000 HP locomotive with AC traction motors. 6000-horsepower V16 turbocharged diesel that runs with in a hair's breadth of the theoretical maximum Carnot efficiency, driving an alternator that can absorb that power. Rectify that, then feed it through a computer-controlled variable-frequency drive that converts it back into precisely controlled AC that works seamlessly with traction control to prevent wheelspin. 3 of them can replace 5 4400 horespower DC locomotives.
Now THAT is a combination of electrical and mechanical engineering!
