Many clocks today that plug into the wall still do sync up with the
power grid. It's the most convenient source of accurate "ticks".
A long time ago I read about an electronically controlled AC power
generator that could control the frequency it puts out electronically
without depending on the rotation speed. Do such things exist, or was
this yet another great idea that never made it to the real world?
