    Obviously some part of the nation can easily be covered by cloud cover for a few days. But this is only a serious problem if you put all of your generating capacity into a few small areas that are likely to be affected by this type of weather. We already have a national power grid, it'd be dumb as hell not to use it. So install many generating stations and storage facilities throughout the country, then when a region can't generate their own power for some period of time they pull from the national grid. So long as we've got a grid and take the average cloud cover for the country into consideration when building out capacity there is no reason for it to be a show stopper.

    I've only been speaking in terms of current electricity usage. But so what if we decided to go all electric and replace all energy usage with electric. You say we'd need eight times more, why not just go with ten and say that we need 2,100 miles of storage tanker farms. That's still not a big deal considering with deeper/taller tanks you could shrink the foot print, that'd be enough energy for the entire USA for one week with not generating at all and replacing all over energy usage.

    Even when the panels are less efficient you can leave them up and producing. Just add the newer panels and increase the size of the installation. The only reason I can think of off hand to replace a panel is if it is actually not functioning, or you don't have room to expand the installation.

    Energy storage isn't an intractable problem, even with today's technology. The following is largely quoted from a reply I made some months back to similar concerns.

    A week sounds like a crazy long time to try and store energy reserves for. The only situation I can think of where that would be a likely occurrence with solar would be the far north where you might get snow coverage and for whatever reason don't clear off the panels/mirrors. That said though you'd just need to plan for a larger insulated storage container for the molten salt. The larger the storage container the more economical because the ratio of volume to surface area where you can lose heat favors you.

    https://en.wikipedia.org/wiki/...

    The wiki page above mentions tanks 30 feet tall and 80 feet in diameter being able to provide 100megawatts for 4 hours. If you use the average electricity consumption of the US as a baseline a city of 7m people would need 11.8 gigawatts of continuous power. So you'd need 118 of those tanks, or fewer tanks with a combined volume in the same ballpark, for every 4 hours of total darkness. My rough as hell calculations say something like 17.5 acres of storage tanks for every 4 hour block, if you go with 24 hours of storage it'll take up 420 acres, or about 2/3 of a square mile. All of that is presuming 30x80 foot tanks, you could save a lot of space by going with larger tanks and at least partially burying them. If you scaled these numbers up you could store 24 hours worth of electricity in molten salt tanks occupying just 30 square miles, for the entire USA.

    I would also add that I've never seen a weather event that blanketed the entire lower 48 for even a couple hours, let alone a week solid. Solar also produces energy even during cloud coverage, just not at 100%. So your proposed week of no power production would require an unprecedented weather event of ridiculous proportions and duration, or one of shorter duration but with a populace that does nothing to mitigate it's affect on power generation. But even if we decided to plan for such an improbable event it is a readily attainable project to accomplish, we'd roughly need 210 square miles of tanker farms spread around the country.

    I was asked yesterday if I wanted to telework today. My answer was a resounding "No!" I'd rather take the time to come in to the office than contaminate my home with work BS.

    My father installed solar panels on the roof of his barn and even in winters with lots of snow he's put more energy into the grid than he's taken back. And that is with no effort at all to clear the snow off the panels. Melting the snow off the panels is probably one of the least efficient ways to clear them. I would instead opt for using a leaf blower and mounting the panels such that they can be reached with the leaf blower from a walkway or something.

    I used to live on a hill in the woods and the number of idiots driving around in 4 wheel drive all the time that got stuck was comical. They seemed to believe that 4 wheel drive was some kind of magical insurance against getting stuck.

    Battery powered vehicles are going to lose some range in cold weather but with a sufficiently large battery, like Teslas have, it shouldn't matter for day to day driving for most people.

    "Now as for failed predictions I am willing to wager a small amount of money that you don't know what the actual predictions made my mainstream climate scientists are.

    On top of that the media isn't going to be interested in spending those valuable five minutes talking about moderate predictions. They go straight for the extremist predictions because that will hook more viewers. Just like so called reality TV programs don't cast normal people, they go for all the crazies they can get because it's more entertaining. I have a relative that has worked as a nuclear plant inspector for decades, and feels that nuclear energy can be done safely.

    I'm pretty sure it's more about mental focus and self discipline. Our minds don't actually let us multitask, at best we switch tasks very rapidly. But I suppose that's being pedantic.

    My wife usually has dozens of tabs open when I look at her computer. She opens articles and such that she wants to read later in a new tab and moves on. I do the same thing when perusing my news feed. The difference is that I usually go and read those articles within a couple hours and close them out. She will stay occupied with other things and end up with tabs that she opened weeks ago still hanging there. When I have an article that I just don't have time for I'll bookmark it and close the tab. Youtube actually has a feature that I love and use the hell out of, and that is the 'watch later' button.

    Neither of us focuses particularly well. I just exercise some self discipline for up to 30 seconds per evening and don't end up with a computer bogged down by dozens of extra browser processes.

    The internet and modern 24 hour cycle media can be thanked for the impression that we're more stressed and divided than ever.

Major political divisions have been with us since the founding of the country, the only real difference today is the speed and omnipresence of the media coverage today.

    Wealth inequality has definitely been getting worse, which is why the middle class is disappearing.

  20. In the past running a VPN from within the NIPR to the open internet was definitely possible. I know because I saw people get busted for it when I was in the military. In every case I knew of it was done to get around the web filters to peruse gaming forums, play games, or get to some other entertainment site. SCIF's commonly have NIPR terminals for every desk as well as terminals for air gaped networks spread around. So I can easily see how someone of a sufficiently high rank in an organization might get away with having an extra terminal setup with a VPN connection to the open internet. Sure regular peons and mid level management might get fired or prosecuted over such things, but top level management is frequently able to get away with anything but murder.

  21. It's still fair to say that the military, particularly the enlisted side of things, is recruited. Yes, ultimately the members of the service are volunteers but all branches of the military have recruiters who spend much of their time actively trying to find people to talk into volunteering. The military also offers benefits aimed squarely at financially insecure groups of society.

    I only served in one branch of the armed services and so can't speak to the depths of indoctrination among them. However I can say from my experience that the branch I was in was pretty demonstrative of the US as a whole demographically although skewed a bit towards the conservative side of things, but that's not really surprising. You don't see or hear military members protesting and striking because the UCMJ would be used to toss them in prison immediately if they did it in uniform or cited their status as military. That doesn't mean they aren't participating though, they just can't advertise their status as that could constitute representing the military.

    While the military at any one time might represent a very small percentage of the population, 13% or so of adult US citizens are veterans. If there ever arose a popular civil war in the US again we would likely end up with two armies largely made up of, and led by people with actual experience. So while hypothesizing about future civil wars or insurgencies citing past one side military vs unarmed civilian massacres isn't very useful.

The plot revolved around a human character that stumbled upon and was accidentally exposed to a fix.
