Fascinating, if anyone has info on other grids that share these types of alerts, pease link!

I'm really curious where that presumption comes from. There are tens of thousands of things that are prohibited due to saftyism. If you understand pressure Regulators and can hook up a BBQ, [is it really] more risky than skydiving Edit: Switched a safety assertion to a question

I'm not entirely clear on what your question is, but reused single-use propane canisters are lesser for three reasons. 1. The propane they are manufactured with is carefully dried, but propane out of bulk tanks is not. The single use tanks have thinner walls with less corrosion protection because the high-end propane doesn't need it. 2. The safety over-pressure valve on those tanks has similar design constraints and…

I was questioning the idea that having a refilled tank in your car is more dangerous than skydiving. I think it is fair to presume it has some non-zero risk.

I was questioning if that risk is meaningful, or if it is like a prop 65 warning on every building you enter, and most products you purchase.

Googling around I was able to find 1 death associated with refilling a DOT-39 container [1], which is scary shit. However, it seems to be caused by a poor coupling, refilling inside, with an ignition source. This could have happened with any container including a certified refillable one.

Can you really call yourself a prepper if you don’t have a faraday cage with a spare laptop inside? (The intersection of doomerism and tech is amusingly cyberpunk sometimes.) Actually, what’s the most useful way you’d prepare for a worldwide grid outage? This isn’t that, but sometimes I wonder if a future CME might be as catastrophic as some say.

Clothing, weapons, some tools, some survivial books. And muscles and brains. And last but not least. Gold and silver. Because that will become the only money.

Last part is a trope but human societies around the world use different things as money, including counterfeit notes in Somali http://jpkoning.blogspot.com/2013/03/orphaned-currency-odd-c...

In fact I doubt gold/silver becomes money because it’s generally too rare and inconvenient (hard to cut the gold bar without tools even if you have one). Realistically people will just keep using cash.

Ercot seems to put some geo restrictions on their page. I've been blocked from viewing. I'm in Australia. When I put on my US VPN, it works.

> The water seems like the hard part. Are there any tricks for cheap, safe hydration for a family? You already have the equipment for that. Your existing hot water heater stores enough drinking water for a month at least, probably more if you ration carefully.

we got the smaller 42 gallon one, and.. with two people and a pet... it might last a couple weeks tops, I'd think, if we rationed (~2-3 gallons per day?)

According to the SWPC[0], the "SPACE WEATHER CONDITIONS" section displays the pertinent information: as of 5/10/2024 at 6:00 CST, the "24-Hour Observed Maximums" list "R3 S2 G4". The "Latest Observed" section shows "R1 S1 G4".

According to NOAA Space Weather Scales [1], the effects of those events, their levels, and the corresponding hazards (including biological risks for the "S" category) are listed.

It is unclear to me what "high-flying" and "high latitudes" mean in these cases, and I would think that they would depend on the severity and location of the space weather event.
