What if power grids ran at a higher frequency, say 100-120 Hz?

we would need new clocks and it would taste more like pain than it allready does.

Would it be more efficient?

Higher freq is more painful?

Yes, it would be extremely painful

>Power frequencies as high as 400 Hz are used in aircraft, spacecraft, submarines, server rooms for computer power,[19] military equipment, and hand-held machine tools.
>https://en.wikipedia.org/wiki/Utility_frequency#400_Hz
>Transformers, for example, can be made smaller because the magnetic core can be much smaller for the same power level. Induction motors turn at a speed proportional to frequency, so a high-frequency power supply allows more power to be obtained for the same motor volume and mass. Transformers and motors for 400 Hz are much smaller and lighter than at 50 or 60 Hz, which is an advantage in aircraft and ships. A United States military standard MIL-STD-704 exists for aircraft use of 400 Hz power.

Modern switching power supplies makes it basically redundant. Also higher frequency -> smaller wavelength -> long transmission lines start acting like giant antennas radiating power into space.

Question is something else:

How do you want to achieve that? You'd need to switch all home appliances in a day or so. Or have some converters.
