40-some terawatts, apparently. We use maybe 20, converting from Wikipedia's 600EJ/year.
Based on that, it's a viable source of energy, but not with much room to grow. The sun provides 3 orders of magnitude more to our planet.

Hmm, I wonder how much heat a lightsaber handle could take before it stops working.
Apparently magma chambers have accidentally been drilled into before.
Edit: That's actually in this article, too.
Skylon is a totally different kind of engine, though. It's has a turbojet with active cooling at the inlet, basically. The SR-72 uses a scramjet at high speeds.
It sounds like the enabling tech was 3D printing, based on the Wikipedia article. There must be a really intricate system of tiny channels within it.
A bit of a bait and switch. The article boils down to "raising GDP slightly at the expense of the poor is bad". Something that's not anti-growth, but pretty much conventional wisdom for anyone who actually pays attention to policy.
Hot take, but (sustainably) having more resources is still good, so yeah, we should keep building solar farms and funding startups.
Yeah, these guys are going to find out pretty quickly that they're not warlords, and you can't Agile, litigate or buyback your way to suppressing a coup. They might still come out in a good position, because they have easy access to nice stuff and important people, and that doesn't instantly go away, but it's not going to be how they imagined.
Kamil Galeev had a good quote on this once: "Innovators are greenhouse flowers, they flourish only in very safe societies". And honestly, a lot of these guys are barely innovators.
TIL! I'd heard of SSTO - and it sounds like you're saying they're a retrofit away, at least for the US government - but not asparagus staging. It's called "propellant crossfeed" less casually, apparently, in case any one else wants to look into it.
I doubt that's the most (financially) expensive component in any of these cases. Making stuff fly is pricey, and maintaining high-bandwidth radio connections can be too.
With that one, at least your parser should crap itself right around where the error is. You probably just need to search engine the error message, and find the page every other noob has to. Then it won't take too long.
If your thing compiles but doesn't work, then the real fun begins. You're in the magical land of Turing completeness, where you hope the problem isn't unsolvable in your case, because it definitely is in general.
Yeah, no joke. That would be awesome, and they wouldn't be scared off by the paper terrorism.
When Mexico sends us us people, they're not sending their best. /s
Ah, that makes sense. I wonder how big of a rocket you'd need for that last step.
Which one? Lol.
