Tomorrow (Friday) the last day to make an official stand against a fuckwit billionaire filling the sky with hundreds of thousands of AI datacenters and destroying the ozone layer.

@impermanen_ The data centres just won't work. Space is NOT a great place for dissipating heat, it's a near vacuum so conduction and convection can't take away the heat, it has to be radiated. A data centre creates many times more heat than the ISS, which has eight 3m long radiators. The cooling array would be huge, and the solar cells for each data centre would be far larger than that. We're talking hundreds of tons for each [EDIT: terrestrial data centre equivalent - however many satellites that is].
Musk is way off base here. He's talking about putting up a million devices, each dozens of times bigger than the International Space Station.
He should be thinking of putting data centres deep in the ocean, if he wants free cooling and energy.
Space Data Centers Are Dumb.
@AbramKedge I’m familiar with the argument (to which I think there is no rebuttal) that cooling datacenters in space would be extremely difficult, absurdly costly, and due to fragility yield no significant advantage. I can only conclude that the man has other motives for owning a million satellites in low-earth orbit that he’d rather not discuss. 🤔
