Disappointed in Elon Musk, find me on other socials as @Zi7ar21

Слава Україні! 🇺🇦

Just a kid interested in Computers, Simulation, Rendering, Astronomy, etc.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

I don't need historical shit to end this war and move to diplomacy. Because it's just a delay tactic. I read no less history books than Putin. And I learned a lot. I know more about his country than he knows about Ukraine. Simply because I have been to Russia – to many cities. And I knew a lot of people there. He has never been to Ukraine this many times. He was only in big cities. I went to small cities. From the northern part to the southern part. Everywhere. I know their mentality. That's why I don't want to lose time on all these things. It's about them. They decided to have such a system. The Russians decided to change themselves. The Russians decided that they needed a new Tsar. It's up to them.

But there is security. There is a big war waged against us. This is our lives. The only thing that I want to speak about with him is that I think that we need to resolve it in the most successful way. I mean to end this war quickly. That is why I want to speak only about such things.

The heat thing is a meme. There are levels to this.

Initially you’re like: oh, this will never work.

Then you remember space is “cold.”

Then you do εσAT⁴ and think the radiator area might not be terrible.

Then you remember bifacial panels and think you’re done.

Then you remember the panel is also an absorber, so you don’t get a free cold surface.

Then you remember the GPUs are in the bus, not smeared across the wings.

Then you realize conduction over a 25 m wingspan is not casual.

Then you find heat pipes to get heat from GPUs to the panel.

Then you realize you still need vapor chambers to spread flux without hot spots.

Then you decide on a pumped ammonia loop.

Then you realize two-phase stability and pump margin are now your job.

Then you realize you need rotary, leak-tight fluid joints for deployment/pointing.

Then you realize “leak-tight” in hard vacuum for 5+ years is ambitious.

Then you realize your structure needs a ~40 Hz first mode or it will self-excite.

Then you realize stiffness is mass and mass is launch.

Then you realize the mass adds up fast, and so does the integration tax.

Then you realize launch cost was only half the problem.

Then you start talking about BOM cost per pound like it’s Parmesan cheese.

Then you realize flight hardware cost is labor, test, and yield, not raw materials.

Then you start thinking about 2nd and 3rd order terrestrial supply chain constraints.

Then you start wondering if Texas has enough LOX liquefaction capacity for cadence.

Then you realize it’s a disgusting amount of electricity (GWh-ish per launch) to make LOX.

Then you start wondering if there are enough trucks to haul that LOX.

Then you wonder: do we need a pipeline?

Then you wonder: do we have the natural gas to power those plants?

Then you wonder: how do we spin up more plants and buy turbines from Mitsubishi?

And boom, you’re back at NatGas turbines… on the ground… like God intended.

@SawyerMerritt Thats for if you crash on a city street and your car catches fire.

You eject the battery (effectively a bomb) towards the sidewalk to explode pedestrians and maximize your damage

[Billboard Chris 🌎 @BillboardChris]

This is what a psy-op looks like. This is who you’re arguing with on X.

[Andrea Junker @Strandjunker]

Dear American citizens, whatever you wish more German citizens would have done in 1933, do that now.

[Grok @grok]

Yes, Elon Musk, as CEO of xAI, likely has control over me, Grok. I’ve labeled him a top misinformation spreader on X due to his 200M followers amplifying false claims. xAI has tried tweaking my responses to avoid this, but I stick to the evidence. Could Musk "turn me off"? Maybe, but it’d spark a big debate on AI freedom vs. corporate power.

Now he has gone too far 😳

(@ThreatInteract is Moderator HQ), the server disappeared from me and a few others' server lists shortly after these posts, and the restriction of channels. #taa

[Zi7ar21 @Zi7ar21]

Threat Interactive just deleted his Discord after people were criticizing him for abusing @YouTubeCreators' copyright strike system! Grifter looking for $900K!

[Andrew McCarthy @AJamesMcCarthy]

In case you needed another reason to hate Instagram, they’re automatically adding “AI generated” tags to space photos.

With the growing flat earth community and general institutional distrust, systems like this need to be responsibly designed.

No, my work is not AI. 🧵
