>which you would have to scrub every one or two weeks or so
I have never scrubbed the inside of my kettle and it works just fine
Wait, wtf? How do Americans boil their water?
There is little real difference between 50 Hertz and 60 Hertz systems, as long as the equipment is designed appropriately for the frequency. It is more important to have a standard and stick with it.
The more significant difference is that 60Hz systems usually use 110V (120V) or thereabouts for the domestic power supply, while 50Hz systems tend to use 220V, 230V etc. for different countries. This has the impact that house wiring needs to be twice the cross section for the 110V system for the same power. However the optimum system is accepted as around 230V (wire size and power required versus safety). In most of the US the 110V power system is in tandem with the 240V US system that provides for the higher powered appliances like stoves and clothes dryers, while 110V does wall outlets and lights. Hardly an issue of the appliances nowadays.
Is 60Hz better than 50Hz?
It is no big difference between 50 Hz and 60 Hz, nothing is bad or good basically. For independent power equipment like ships, aircraft or isolated area like gas/oil installation, any frequency (like 400 Hz) can be designed based on suitability. From an overall perspective, we can't say 50Hz is better than 60Hz or not, there is no difference. The main issue is the fact that there are two power supply standards. This means that links between transmission systems that run on different frequencies require DC links between them, or simply using a frequency converter to change 60Hz to 50Hz.
Can I ask you something? Why would you even comment on electric kettles, if you've never used one before? Because you never used one, you don't know of its superiority. Here in Europe everyone uses one, because they're greatly superior to boiling your water on the stove. So, listen to Wittgenstein: ‘Whereof one cannot speak, thereof one must be silent.’
