My son lives in Santa Rosa south of the Kincade fire, currently 5% contained and 66000 acres burned. He’s in not in a mandatory evacuation area, but the air quality due to smoke was so bad that he and his wife and baby left anyway to house sit for us in Berkeley. The air around SFBay is better but not great. He works for Keysight Technology there in Santa Rosa, and they sent everyone home I think last Wednesday or Thursday. Keysight was hit by the Tubbs fire in 2017 and lost one building to it. That included the historical Hewlett-Packard Packard archives.

Sadly, fires are part of fall in CA; we have been dry since the spring and the Santa Ana winds create conditions that allow fires to start and spread rapidly.

I visited HP Santa Rosa in the early 90's. I've never since seen such well appointed office cublicles with so much test gear.The powering down of the electricity network is an interesting idea. The power network is often to blame for sparking bushfires here in AU. Here is a lot of activity going on trying to detect and react quickly to faults, maybe they should just turn off for the worst periods

... What I don’t yet understand about that is how you can bundle the conductors and still carry the 10s of kilovolt that are necessary for lower currents and efficient use of copper.

One method is to use sulfur hexafluoride gas (SF6) as an insulator.
