I don't really get the "nightmare" consequences. Sure, some electric systems will go down / maybe burn down. But few people will die, right? When I saw nightmare in the title, I expected something like humanity will be wiped out, or maybe just 90% of us. Can somebody clarify?

Remember when Texas lost power for a week? Imagine that nationally for potentially months, no food, no water, no communication.

It makes sense to keep food and water, only if you also have protection. I mean a weapon. Because those 20 million zombies are coming.

It only makes sense to have protection if you are going to have enough protection to fend off all 20 million of those zombies.

That is what community is for. I would imagine an armed community would be in a better situation than an unarmed community or unarmed individuals.

The nightmare scenario is a follows; You get a really large solar storm and no one notices it, so all of the high voltage grid transformers are connected to the grid.

The currents induced by the grid burn out these transformers and they have to be replaced before power can flow again. But these are very large, long lead time items that we don’t leave just laying around. And now you need hundreds of them, but the supply chain to build them has collapsed.

Thankfully, most of these transformers are connected to grids that automatically detect the high DC currents and shut down. And this assumes everyone missed the massive impending space weather event and grid operators forgot to shut them down.

So it probably wouldn’t be that bad.

This kills all the satellites in our orbit as well? Satellites are already vulnerable to solar events and magnetic anomalies like SAA.

In additional to everything on Earth being wiped out would this would create a mini Kessler Syndrome since all satellites are now space junk which we will never be able to communicate with again?

Yeah, that's what I'm getting at. I don't see how it can fall apart of it's mostly self sustaining. There are still loads of people in my hometown that don't have power. What are they gonna lose if society falls apart? lol Lots of the local trucks run on vegetable oil so they don't even need a working supply chain for diesel. It'll be an inconvenience but it's no death. On top of that, a huge amount hunt and fish lik…

Well if us city dwellers will turn into savages due to lack of any food, the first thing we will turn into is go out to those nice farming communities for food. Obviously if your nearest big town is 500-1000km away then you're OK for some time. Maybe.

It's certainly a significant problem, and one that would cause some intense short-term pain, AND one that we should just bite the trivial cost and make a spare set somewhere for, but...... It would take years in normal times. In a crisis like this, you'd see resources allocated to transformers on the scale of (perhaps greater than) that allocated to COVID-19 vaccines and PPE, and that time scale would almost certainl…

After what Texas experienced, a dramatic reduction hardly seems sufficient.

What are you referring to?

In the U.S., there was a study, with results published by the EMP Commission, indicating that as many as 90% of people could die within a year as a result of a pulse event hitting the electrical grid.[0] I don't know if the same extends to other places, but once distribution and sanitation systems break down, which are heavily dependent on electricity, it'll become pretty clear very quickly just how ill-equipped we a…

And EMP is a totally different phenomena. With EMP you have the prospect of burning out microelectronics. That doesn’t happen with a solar storm.

Context: No power, societal fabric is breaking down, credit cards don't work. Assumption: people will accept crypto at any value. Reality: people will barter for tangible items and use force to maintain their desired order. If I'm auctioning a spare 10kw generator the guy offering a 5.56 rifle and 100 rounds has infinitely more value than 100k bitcoins (~$5,000,000,000.00) Maybe this fantasy can play out if the perso…

Right I think that will happen as well, I am interested in better price discovery instead of arbitrary barter. I will support the cause to build the infrastructure for better price discovery. Transactions can be broadcast to the chain which is supported by an asset with many assurances and confidence about its supply. I don't actually care about the cryptocurrency being a reserve currency or any ideology fantasizing…

I legitimately do not understand what you're getting at.

Society collapses, and you believe people will use cryptocurrency for barter instead of tangibles like water, food, ammunition and/or weapons because people will want to optimize the prices? What are you saying?
