  • The ISS has a lot of big solar panels. The other big panels they have are thermal radiators.

    They have to have quite large thermal radiators because it’s very inefficient. The ISS has people and a very small amount of computing power.

    Data centers generate several orders of magnitude more heat. You would need several orders of magnitude more thermal radiators than you would solar panels. The bigger you make the data center, which is important for density since you’re introducing a lot of lag due to the speed of light, the less room you have to put thermal radiators or solar panels.

    Then you need to work out how to get spare servers, and/or server parts up and down from the Data Center. All of these things are consumables, and all of them have significantly more wear and tear outside of the Earth’s atmosphere.

    It is possible. It is not efficient or sensible. It sounds cool, it doesn’t require buying land, and there aren’t currently international agreements about doing dumb stuff in space in the same way there are for doing dumb stuff in the ocean.






  • I want them to survive so bad.

    I don’t need my vehicle to be a third place. I don’t want a molded dash with an entertainment center that will be obsolete when it’s new and unable to be modified because they abandoned the DIN standard so you could only buy factory replacements. I just want a thing that can do ~50+ miles a day and recharge that overnight. Which Slate could do with just a regular 120v outlet.

    Who knows if they’ll actually make it to market or if it’ll be $40k+ by the time it does, but even without the EV incentive $28k puts it among cheapest new cars in the US. I’m just severely unenthusiastic about any other newer cars on the market if my current one dies.


  • Cycle count is important for the lifetime estimate on the battery, how long before you have to spend a large portion of the cost of the car on replacing / refurbishing a key component.

    “Fill up” time is the most obvious and common ‘maintenance’ anyone will ever do on their vehicle. One of the biggest objections large swaths of the population have about EVs is/was that could take an hour or more for each stop on a long road trip or if you can’t charge at home. (apartment / street parking / etc.) They usually do 10-70%r 80 or whatever because the speed trails off exponentially closer to 100%. (logarithmically? whichever.)
