@dev Oh yeah, that's the guy who runs the https://www.youtube.com/@PracticalEngineeringChannel YouTube channel. Pretty awesome channel; I learn at least one completely new thing every episode.

(This week's "Oh shit of course": if you have to bring two chunks of the power grid together that are already energized, they have to be synchronized when you cut them in or the moment you connect them, the AC on one grid will fight the AC on the other, trying to drive every generator as if it were a motor. That'll blow you right back off the grid and possibly damage equipment if you're not sufficiently circuit-breakered, so every power station has meters to measure grid phase... But the cheapest meter is a lightbulb slung between the two grids, because if they're in sync the relative voltage between them will be zero and the bulb won't glow).
