Airship Transporting Grain - Postcard from a Solarpunk Future

Reply in thread

It is conceivable that unlike boats, autonomous airships may not need to be super big - they scale linearly. So a continuous swarm of small, lighter than air evacuated diamond foam devices could come, pick up stuff, and depart for local targets or far away targets via the jet stream. That also removes the need for the tower - they could pick stuff up right from the harvester.

Trump 2.0: The climate cannot survive another Trump term

Reply in thread

I don't think anyone questions that humans will survive. It's just unlikely that the complex global supply chain that gives us complex tools like microchips etc will survive. And may be massive famine etc after just a few harvest failure, or after the grain can't go down the rivers to the sea any more. Naturally not for the very rich, you can probably buy a bag of rice at a price. It's not survival that's at stake, its civilization and all that.

Researchers argue that reducing greenhouse gas emissions is not enough to combat climate change

Solution is a maybe an overstatement, but

  • destroy the methane. That's energetically favorable, so it can be done more easily. Makes some CO2 but it's 50x less bad that way.
  • get the carbon back out and stick it into the ground. We'll be on our way when the Mauna Loa CO2 curve bends and goes down for a year or two. That's energetically expensive, but we'll figure out a way (hopefully) to do it wherever we have solar overproduction.

Trees are nice, but it's nowhere near enough to do that.

SLRPNK community discussion - November 2023

I suppose it helps to qualify what you say. But then it may become quite unreadable.

Even "Today is Thursday" is questionable. Where is it today? Do you mean right now, right here? What calendar? Somewhere it's already Friday. The "day" is just rolling around the earth, etc. It's more defensible to say at the time of posting this it is Thursday in California.

The philosophy people have a thing where you posit a thesis and then present counter arguments, and then counter these again (and, in medival time, counter the ones that are non-dogmatic once again to make sure you don't get burned alive).

The Chinese had a seven legged essay, I think it went back and forth 7 times, and the conclusion was left up to the educated reader, in contrast to scientific paper standard today where we explicitly state the conclusion.

Exploring and to some extent preempting counterarguments may be helpful in any case.

German primary energy consumption drops by 9.0% and emissions by 11% in Q1-3 compared to 2022

I suppose that's pretty much guaranteed. I am worried that the supply chains stop working before we get serious about climate repair. It'll be interesting to see what happens to the fossil fuel companies when the "proven resources" in the ground become worthless because there are barely any buyers anymore and borrowing against it is no longer possible. I don't know how much they do that - but it would have implications for the finance people.
