  • That’s a little different.

    Items that can expire get marked down at some point during the day, but they aren’t changing the normal price of the item. If there’s 20 packs of chicken breasts on the shelf, 5 or 6 might get the sticker.

    There’s no guarantee that the one you have would have even gotten a sticker, and if you’re savvy enough, you might have intentionally chosen the pack with the earliest most recent packed on date, or gone late enough to be after the mark down time near the end of the day (at least where I am)

    They aren’t just going up and marking down the main price on everything, and its also always down, never up.





  • Ya, the economies of how much total space / material for the global network is similar, although lets say higher due to losses in efficiency in distributing it over so many dishes, but in terms of how big any individual radiator is and how much space each one is going to take, the smaller sizes make it easier to manage. Trying to figure out a 150-200m2 solar panel radiator is a lot easier than trying to figure out a 1km2

    The individual power of each satellite having to use a mesh network to train might not be fast enough, maybe they’ll still use land based ones for training, but no single person needs more compute than what a satellite can provide. So from the inference / customer computation side of things, it isn’t a problem.

    edit: I meant radiator, not solar panel

    edit: looks like blackwells can run sunstained at 88c, so that will help a bit more as well on size, the calculator now says 103m2 instead of 127m^2



  • For 100kW? I’m not going to try and figure things out from that massive site. A pre made calculator would have been nice if they had one.

    edit: It is going to be LEO and likely connected to starlink with the same laser link they use.

    Edit: Looking at orbits they might use sun synchronous orbits? It might not be in sun 100% of the time, but they are nearly always in sun.

    Edit: I have no way to know if this is right, but a couple AI responses are saying for 100kW it would be ~150-170 square meters with temperatures around 70c


  • We already radiate heat away just fine in space, it’s just a matter of how much space do you need to use to do it and all the implications of what that would mean for any given satellite. I wouldn’t call it free, because you need the hardware to do it and the extra weight reduces the payload capacity of whatever you’re sending up, but we can do it.

    Starlink also uses laser links to talk to each other which these satellites would also use. How they work can depend, but generally they bounce around in space until they can’t, and they might come back down to land, to move somewhere else over fiber to another ground station until they can go back up to reach you. But the more laser links the less they have to come down for technical reason, but they might still come down for bandwidth reason. I don’t really know how likely it is that any given connection is point to point.

    Example of what could happen.

    Your dish -> starlink -> starlink -> ground station -> Google -> ground station -> starlink -> ground station -> starlink -> groundstation -> starlink -> starlink -> your dish.

    Fiber is still the better option on land if you can get it there, but there are a lot of places it’s never going to get laid, and will never be in the air, or on bodies of water.

    Edit: Corrections on the laser links with an example.
