Lithium is surface mined from dried lake beds and oceans right? Big equipment pulls off the top layer of salt and soil from the ground? Cobalt is the one with open pit mines, horrible working conditions, and health concerns.

Lots of different estimates, but looks like between 11% and 20% of ghg emissions are livestock. That’s way higher than I thought.
Median income or ihdi are much better indicators of people’s well-being.

The economy/gdp is just a measure of how much stuff you are making, not who is getting it.
4.8kg per day gives 1.75 tons per year, giving an 800% increase. That’s still really big, thanks for tracking down the numbers.
48 tons per day, so it’d need to be less than 0.08% aluminum to double it.
Yeah you’d need to put up fewer sats per launch. But they might still have enough lift capacity on starship to do that.
Wood is interesting, but the article doesn’t address off gassing at all, which is a huge problem for communication satellites. Is there a way to keep the wood from off gassing? For 3d prints in vacuum, they metal coat them to keep the gas inside. Or maybe you could resin soak them? With hopefully an extremely UV stable resin. But I didn’t know what the weight trade looks like then, resin is heavy.
But if you’re looking composites anyway, carbon fiber would be another great option. Lightweight but with a few manufacturing constraints. But should burn up to carbon dioxide on reentry.
About 48 tons of meteorites enter the atmosphere every day. I couldn’t find the elemental distribution, but I’d guess there is some aluminum in there. How much of an increase is 14 tons aluminum per year over the many tons of aluminum entering the atmosphere already? That might be good to get a rough estimate of how impactful this is.
SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.
Magnesium comes to mind that would be light be expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides?
And the depth of focus is incredible!
Wolves are apex predators. Or were till we turned them into poodles.
That seems like an inherently false statement. If it was sarcastic, it would be false because it actually is going great. If it’s not sarcastic, than the project is not actually going great.
Have any countries named their EEZs?
The hard part morally is whether future human rights trump present ones. But we can’t even get to those issues since they’re all trumped by maximum short term profits all the time.
Lol, Microsoft will focus on profits and shareholders, and shareholders want AI cramed into everything.
Here is what it is currently
Ralph will only come back into existence next time this is reposted. For maximum existential horror, change the name every repost so Ralph is forgotten.
I couldn’t find that exact graph to the 2020s, but here are some more.
There are 16 thrusters on the service module and they only need like 4. One is malfunctioning. They’re trying to diagnose the problem to fix it for next time since the service module burns up on reentry.
