Wait, was that a PAL/NTSC joke, or do they really move at a different rate in the US?,(reply>), @Wesley Miller Wow! 24 hours ago you knew nothing about power generation, and now you're the expert. You sure are a quick learner. Respect.,(reply>), Ok. But again, that disproves your initial comment because there is the benefit of more power output. (Obviously because it's American),(reply>), @Wesley Miller Well it would if output voltage was the only factor.  However, faster running also increases wear and tear, and the unit has to be made beefier to withstand the rotational forces. The actual decision was a compromise between power output, building costs, and maintenance costs.,(reply>), +Mandolinic then doesn't that periodically disprove your theory that 50 hertz is better than 60 hertz?,(reply>), @Wesley Miller The generator has to run faster than 1Hz in order to generate any worthwhile current. With any generator, the faster you wind it, the higher the voltage. Also let's not forget that at low frequencies, the lights would flicker noticeably.
