I was talking about the direct emissions of launching a rocket. The indirect emissions are obviously vastly larger and might as well include everything in the wider economy that enables stuff like this. Just maintaining the necessary industrial capacity is already a huge strain on the planet. That's what I'm after with these comments. The rich fucker joyride is a largely inconsequential yet overtly visible result of a bloated system hiding in plain sight. The aerospace sector as a whole is just the tip of the iceberg of a global industrial society in ecological overshoot.

Yes, the comment I replied to is technically right in that there are some tiny countries out there. Or they would be, if the rocket in question would've been a vastly larger rocket that burned a carbon containing fuel. The New Shepard tourist joyride is tiny for a rocket and its exhaust is water vapour.

I hate rich fucks as much as anybody, but this particular vehicle uses liquid hydrogen and oxygen for propellant, so no direct carbon emissions from the fuel.

The spacex superheavy is the biggest rocket stage around and has somewhere around 1.7 million kg of methane in it at launch. That results in about 4.7 million kg (4675t) of CO2 when it's burned. That's the same as the yearly emissions of 338 average americans, or 962 people at the global average.

Rockets are big, flashy and make a lot of smoke, but the numbers really don't amount to much when compared to the sheer scale of more mundane economic activities.

I hate ai slop with a burning passion. This channel on the other hand is actual ai art.

I'm guessing that it's not that simple. They'd need the associated ground infrastructure and an increase in budget to cover the maintaining of it all.

I think they might mean all european social media users. The vast majority of those are still on corpo socials.

Or a night shift. I'm on my way home after one right now and I've been awake since yesterday afternoon, so about eighteen hours.

How do you think the hunter-gatherers got their food? They didn't drive around delivering berries to each other while worrying about credit scores.

The difference between a sauna and an oven is that the heat is transferred from the heater into the air by pouring water onto hot stones, which then boils off and carries its heat and humidity into the air. The rocks have to be hot and have sufficient heat storage capacity to also stay hot even if more water is thrown at once. Having a hidden main heater would be a huge hassle to get the humidity right with some automated system, while also taking away the fun of throwing the water yourself.

Since the hot steam rises up, the benches should be up high enough that people can ideally get their feet above the surface of the stove. Hot air rises up, but the temperature gradient isn't completely smooth. The rising steam mixes the air around a bit, so below that the air doesn't mix all that well and the heat drops much faster the lower you get.

In this one, your entire lower half is in that significalntly colder air and the vast space above you is where the heat escapes to, far from your skin where it's no use to anyone.

Sure looks nice, but that sauna can't produce an adequate heat. The benches are way too low and the heater is utterly undersized. One's feet would be getting cold even with a heater five times the volume of that one.

Also yeah they should try having less money.

My gaidar (generative ai radar) is going off.

I think a good old shitass paint illustration would be preferable. The message itself is good enough to deserve at least that.
