Let’s say there is a limited nuclear war. Military sites and major cities are hit by ICBMs, but bombers are called off mid-flight and only a few SLBMs are launched before a ceasefire is agreed upon.
High tech factories were destroyed in the cities they were in, but rural fossil fuel industries remain intact.
What is the best option for restoring power to the country during recovery?
I was thinking about this in the shower and wondering if survivors of a nuclear war would ever be able to have hot showers again.
Would coal be the most viable route for a quick recovery? I’ve heard China has mastered building them pretty quickly.
Or would renewables like solar and wind make sense, if countries that have industries for producing such infrastructure escape the war unscathed?
Solar hot water is fairly easy, as long as you have something black and watertight. Wind generation requires less tech than solar PV, although concentrated solar thermal would be similar to wind, aside from steam handling. This assumes the sun is still shining, not blocked out by clouds.
AFAIK, military industrial would be primary targets, with population centres being collateral damage. So most useful industry (not including useless consumer goods) would be wiped out.

From what I saw from pork chop plots, there are some times where the dV cost doubles or triples or more…

Okay, so a booster airframe has made 20 flights. Does it still have any of its original Merlins? What is the most flights for a Merlin engine?

Geez, it might have been back in the 80s or 90s (maybe later, but don’t think so) that I came across an article suggesting that the blocks that built the Pyramids were poured, based on inclusions like hair. But apparently the theory never gained traction at the time…

Now I'm wanting to binge watch terrible scifi to compile a list
The Battlestar Galactica reboot was pretty good, and they took a more realistic approach to space battles, although it still seemed to somewhat degenerate into point-blank brawls…

Even better, have SpaceX partner with DoorDash for the mission and require NASA to officially request the sample return via the DoorDash app. Proper channels and all
You know, this is certainly a huge advertising/sponsorship opportunity for a business like that, preferably one with deeeeeep pockets

Would it not be simpler to just build a solid rocket motor into the base of the penetrator, to be ignited at the best point in the trajectory?

oj simpson was killed by
flattus maximus' battleaxeprostate cancer. whether he did it or not is an exercise for the reader.Yeah, the imgur community has not been kind about this. IMO he's not worthy of making the thread title.

They've already had to disable most of the equipment because if power concerns. I'm sure they've got memory to spare
They certainly don't need camera software any more...

The biggest issue would be having the necessary resources, mainly fuels and ores, in economic reach. Can’t do much without iron ore and the coal (or oil?) to smelt it.
Perhaps the most civilizing advancement would be electric light, but that would probably be too close to witchcraft…

If I'm not mistaken, this will be the 5th vehicle reused for an operational flight (Shuttle, SpaceShipOne, New Shepard, Falcon 9, Electron), and the 3rd for an orbital launch.
You could add SpaceShipTwo to that first list. There are also the Dragon capsules to consider. I wonder how Dragon turnaround compares to Shuttle turnaround…

In any event: I am blown away. Unable to really express it. It’s the most amazing thing I’ve ever seen, by far. Doubly amazing because we were getting married during it.
Congrats. That's certainly one way to make it memorable

I think we were supposed to get something like 23% here. But I was inside working, clouds and rain outside, so, meh. But anyways, happy to hear that for some of you…

May the clouds be ever in your favor...

Let me think about that for a second... Um, no. Do you want to try standing while pulling 6 gees, and still control the aircraft? I don.t, not even if it's fly-by-brainwaves.

I’m assuming to get the blue flame with kerolox (although that tweet doesn’t specify lox), they must be running lean (oxy-rich). I believe the usual glowy orange of kerolox exhaust is from glowing soot (unburnt carbon) particles

It's workiiiing! Well, after not working for a month, as of a few minutes ago I can properly access the S&SF subforum on mobile again. This, after I thought I was running into a new bug: "Hey, where'd the "Next Unread Topic" button go? I was just getting ready to post about it before I realized I had run out of unread topics; I must have hit the "mark all as read" button sometime in 2022...
I even went so far as trying to convince Dall-E to create something like a kraken wielding a banhammer....

Maybe I'll catch the next one, when was it supposed to happen again?
Well, I won't be catching this one. I'll have to head for Alberta in 2044. Alaska in 2033 is a possibility. I don't think I have until 2099...

Well, the scope and scale is certainly impressive, and I imagine it costs about as much too…
Lego should put out cheap sooty Falcon 9 kits with all pieces except payload having been previously used …
