He addresses this some. 120v is still a lot faster than boiling water on the stove. Coffee makers are significant, but boiling water in a microwave is generally a bad idea, given the risk of superheating (not that people don't do it.)

I have never once (unintentionally) superheated water in a microwave, and I've been using them since about 1980 (and God knows we were idiots with them back then).

It just doesn't happen - there are too many imperfections in our containers, and too many minerals for it to happen much.

I've experimented many times, and the reality is you have to work at superheating water in a microwave.

For me, it's taken things like a brand new Pyrex measuring cup (glass), and filtered water. I can do it with other stuff, but I've had to boil/cool it multiple times, something that isn't really going to happen.

Huh. I have. Didn't know what it was, but heated the water, dropped in a spoon and it boiled over aggressively even though it didn't look like it was boiling.

We do use a kettle, this happened at work - the microwave there was a lot stronger than mine, and I couldn't get the water to look like it was boiling.

Same here, happened when I was young. Thankfully I wasn't holding it in my hand, it was on the counter. I didn't get burned

He goes into it in another video on the channel. Almost everyone I know uses a microwave for water.
