  • The temp is low but it is a vacuum. Vacuums are bad at dissipating heat. Think of the vacuum walled drinking vessels. They are so efficient at keeping beverages hot/cool because the vacuum insulates the majority of the surface area that heat can move across.

    Likewise a cooling tank of water (typical nuclear reactor design) itself surrounded by vacuum, will not cool efficiently at all. Presumably they’d have to use piping to circulate the water over a large surface area of some other medium like the moon rock itself.



  • She posted about this. Basically the party aparatchiks came to her house and told her to stop her “subversive” activities (posting on YouTube, talking about devices useful to protestors, mentioning being a lesbian in public media) or she would not like the consequences. She said she would leave the country entirely, except her romantic partner cannot leave (I assume this is due to political travel restrictions or family reasons).

    I think her content was awesome and it showed someone defying expectations of who can do product design, fabrication, electrical engineering, etc.

    China should very much get roasted for silencing speech.














  • Right, they need close air support, infantry support, scouts, supply chain logistics etc. all working together to be peak effective. If you just give some dudes an Abrams and a crash course in driving it and firing the main gun, they will be better off than the same crew of randos in a technical made out of a Toyota Tacoma, but they will still be vulnerable to modern threats.

    It’s easy to understand why the modern drone threat is uniquely game-changing if you think of war like chess. Most advanced powers have now figured out that having a developed drone program is like giving yourself infinite pawns. You keep trading pawns for the opponents more valuable pieces. If Russia is able to spend a few thousand in drone hardware and explosives and destroy a multimillion dollar tank, they’ll make that trade any day.




  • There are instances or subs here that will delete your comment or ban you simply for posting something that disagrees with the predetermined consensus they are going for. And no, I’m not talking about racist or abusive comments, just generic shit that may not perfectly align with their narrow personal Overton window. I’m not going back to Reddit, but I wouldn’t say there is a robust and diverse discussion here either. A lot of groupthink, or perceived groupthink…because dissenting opinions get straight up deleted.
