Living in developing countries taught me to never plugin expensive computers without a surge protector UPS.
Do you still need a UPS if you have one of those household (Powerwall style) battery packs? Also Apple switched mode power supplies are pretty well built. But then again there's horror stories like https://www.reddit.com/r/applehelp/comments/1maegvb/i_burned...
Depends on how they are configured, I think in some regions (where power outages are very rare), they are wired to sync up with external network, and without external network they shut down as well.

I like the guy, but he was GOP-lite as a president, served corporate interests.
The GOP isn't "crypto-libertarian" by any stretch of the imagination. That's probably even more absurd than the people who suggest the GOP is "financially conservative".
The thing there is the GOP was financially conservative a few decades ago and it's like nobody bothered to update the wiki.

Areas with lots of thunderstorms. Also more rural areas with long power lines with few taps off for customers — the long runs are both exposed to many nearby strikes and accept induction well, and the few customers are fewer power sinks to dissipate the spike. So, you're more likely to get hit, and hit harder.
Sounds like if you're in an urban area with buried lines, you don't have to worry?
I would recommend a circuit surge protector in urban areas.
Lightning getting through some structure and hitting the electric lines happens. Even when they are buried. It's less of a problem when the ground absorbs a lot of the power before it even get into copper, but it's even less of a problem if there's some cheap device that will burn and protect you from it.

Commercial uses layered surge protectors (Type I, II, and III), which is also recommended for other users but rarely followed. In surge prone areas, at a minimum I would have good quality whole-house surge protector (eg Siemens 140 or Eaton 108), and a good quality surge protector strip for any computer/TV/phone charger. I also put surge protectors in front of expensive white goods like the fridge, washer/dryer, dish…
>In surge prone areas What areas are surge prone?
Open aerial wiring can shortcircuit two phases, bringing a low impedance surge that can damage most electric and electronic equipment.

#379Freight rate volatility is one of the most underappreciated risks in physical product businesses. During the 2021-2022 shipping crisis, ocean freight from China to the US West Coast hit $20k+ per container — a 10x jump that wiped margins for importers who hadn't hedged. Air freight as a backup is worth keeping in your model even if you never use it; knowing your break-even point at air rates tells you a lot about product viability.

The big problem is purity. Fabs use grade 5 and 6 helium where contaminants are 1-10 parts per billion. The infrastructure to get it that pure becomes very specialized and any time the helium goes through a process it picks up so much contamination that recycling it would require the entire purifying and quality control infrastructure for pressure or temperature swing adsorption. Some fabs are starting to reuse heliu…
> The infrastructure to get it that pure becomes very specialized I think some of the most advanced fab infrastructure is the ultra pure water system. Water becomes quite aggressive chemically when it has no dissolved ions in it. You have to use exotic or highly processed materials simply to transport it around. If the factory didn't need such massive quantities of it, trucking it in would likely be preferable.
Ultrahigh density polyethylene isn't that exotic.
