Starfish Prime wiped out 1/3 of the LEO satellites. You can count on your GPS going down. It also burned out street lights and set off burglar alarms. It did not disrupt radio or TV broadcasts. It did not burn out any transformers. You do understand that what you see on the SciFi channel is not real, don't you?

I can guarantee you the interconnected electrical grid in the USA is at risk. Both from Natural disaster as well as physical attack. .......... Sheesh I give up! Don't be ready, don't think it can't won't happen. I couldn't care less. Me and mine will be fine while some of you will be in the dark. 60k gallons of Diesel in a relatively hardened sight on a fresh water lake will make sure of that.......
The sun still comes up every day, and there's a decent moon about 2 weeks out of every month. Do you remember the story of all the horrors that happened in the sports stadium after Katrina? When the sun came up, it turned out none of them had happened. People were just afraid of the dark. You may have found a way to avoid your fears, but you have not been engaging reality.

Larry please allow me.....The very vast majority of big base load plants do not have "black start" capability. Meaning that they cannot "start" themselves without electricity. A 1000MW coal plant needs @ 15MWs of station power to start up and keep running. Grinders, elevators, car un-loaders, emissions control equipment, cooling systems, SCADA system all need electricity. 15 MWs of self exciting generator ( every generator I have seen is self exciting) will cost @1100 bucks a KW to install....Here are 2 examples of black start self-exciting gensets. The Cats are new and the Coopers were installed in 1975.

And I would think they get better at hardening satellites as time goes on and the society becomes more dependent on GPS.

And I would think there are numerous small power plants all over the place that would recover quickly from any general problem. That provides the seed power to start up the rest...like Kodak in 1965

i also find a good bit of it silly. Where do preppers go for surgery? For Chemo? For an angioplasti. I have had at least 5 of these things over the last 30 years anyone of which would have been fatal.

How do lyou deal with illness particularly of the epidemic sort. You avoid the big kahuna to die two years later of cholera?

These might help some understand the complexity of the problem...Linda you may want to pay attention to slide 15 I believe..

Then again this National Geo Special might be easier for some posters to understand....

I wasn't thinking of coal or nuclear for a cold start. A hydro plant is much easier to start, since all you need is minimal excitation to allow one turbine to bootstrap, and at least one penstock can be operated manually for that purpose. Once Grand Coulee is up, it can light up the rest of the US. Get the lines back up and the power will be there. East Coast would be almost as simple, since one of the big nuclear Navy ships could backfeed the grid to get your smoke belchers back online.

Ok I can guarantee it won't work that way but you be happy thinking it will....BTW you know a couple of angry natives with a Barrett light 50 or even an AK if they got close enough, could shut that salmon killer for a year?.....That's what we worry about more then anything The sun is pretty low on the radar screen. Attack and Renewables are the big concern..........maybe you should have tried to read the links I sent earlier.

For a lack of knowledge, my people perish....

A wise man foreseeth the evil, and hideth himself, but the simple pass on, and are punished...

You are dealing with some of the modern, attention-deficit-by-choice crowd. They will not read anything you offer,because it does not say what they want to hear. Like a lot of folks in DC and elsewhere these days...

Some folks will not understand the complexity of running modern infrastructure, any more than they will understand the compounded complexity of starting a cold system back up, because they refuse to consider the fragility of their current paradigm. They will still have their eyes screwed shut, their fingers in their ears, and shouting "lalalalalala" at the top of their lungs when the ride stops. They will likely keep on doing that, because the new reality won't suit them at all...

In so many words, you are wasting your time.
