    People of Earth, your attention, please. As you will no doubt be aware, the plans for development of the outlying regions of the Galaxy require the building of a hyperspatial express route through your star system. And regrettably, your planet is one of those scheduled for demolition.

    The process will take slightly less than two of your Earth minutes. Thank you.




  • Gates don’t give a fuck. He’s really wants to do the right thing and leave a solid legacy. Call him greedy, and he certainly was in the day, but he’s no longer concerned with personal enrichment.

    Money is a drug, rich people if anything are more greedy for each dollar they get than poor people because their tolerance goes up and they need more and more power/money to still get high.

    Any amount of money billionaires like Gates steals from workers has to be just the beginning or else his high will peak and then fall and billionaires will not accept a cold brush with reality/mortality like that.







  • HiNa supplied sodium-ion batteries for JAC Motors in 2023. Early batteries had lower gravimetric energy density (145 Wh/kg) and volumetric energy density (330 Wh/liter) than LFP, but sodium-ion batteries have already improved since then. They have outstanding temperature range, yielding 88% retention at -20°C. For reference, the discharge capacity of NMC at 0°C, −10°C and −20°C is only 80%, 53%, and 23% of that at 25°C. The HiNa batteries had a cycle life of 4,500 cycles with 83% retention and a 2C charge rate, but even better sodium-ion batteries are on their way.

    These developments point the way to much more. The cost of sodium battery materials is much lower than for any lithium battery. There are no resource bottleneck materials like cobalt or lithium to contend with. In addition, aluminum can be used for electrodes, whereas lithium requires copper for one of the electrodes. Carbon or graphite and separator materials will be similar, but in all other respects, sodium has much lower material costs. Compared to LFP, sodium does not require phosphorous, a substance that is almost exclusively sourced from one state in north Africa, nor lithium, a relatively abundant but more expensive substance than sodium. LFP cannot compete on material costs or temperature range, and both BYD and CATL expect to phase it out first in energy storage. ‌





  • This was something that was lost in the aftermath of the brutal killing of Charlie Kirk, I am not on Instagram, I never watched the video because why would I? I don’t condone shooting people because you don’t like them, so despite the fact that I fucking hate Charlie Kirk’s guts, why would I need to see the violence literally? To believe it? To witness it? Watching gun violence doesn’t do anything for me but remind me of how uncomprehensibly awful gun violence and in general violence is…

    The thing is, I noticed how many people around me who were on Instagram saw it without really wanting to, it was almost a foregone conclusion from their perspective they would be exposed to it. That is fucked up, why don’t we all collectively realize that?

    This is a choice in architecture, in social media governance, it is something that we shouldn’t let conservatives get away with, they can’t manage this stuff because they are incredibly childish and unserious about realworld consequences and are unwilling to learn from realworld lessons or history. Rightwing billionaires shouldn’t control our social media because they let this kind of thing proliferate, they encourage it. They want us to be shocked by a violence appearing on our feed without our agency, it puts our brains into a flight or fight response so we can be manipulated, made more afraid and intimidated into feeling powerless against forces of violence and wealth.
