  • Part of the problem with teslas is they will sometimes do the phantom braking even when not on autopilot. My gf has a model 3 we bought back before F-Elon went full mask off, and there’s a certain road we occasionally drive where the car will just slam on the brakes for no reason wherever another road joins the main one. We both refuse to use autopilot but it still does it with even normal cruise control active and sometimes even under full manual control. Its a serious problem. We’d replace the stupid thing if we could afford it but its devalued so much that its more affordable to just keep it.



  • They don’t float, they’re fixed in place at depth. They use the pressure of the surrounding water to spin a turbine as its pumped in and out, the only moving parts are the turbine and its associated components. And seeing as how the water is pumped in and out, most of the silt/detritus pulled in during filling, would be pumped out during draining assuming a siphon tube is used to draw the water from the bottom of the sphere (where all the debris settles) to the pump.

    Yes salt water is corrosive, but that problem is already solved, there are currently concrete oil platforms built in the 70s and still in service today. We have formulas for concrete that are proven to be seawater resistant.

    Building storage tanks on land wouldn’t be as efficient due to the greater pressure differential at 500m underwater vs on land. Dams are one of the most expensive structures to build and are very damaging to the surrounding environment. They also have a much larger problem with silt deposition as there is a constant flow of it, every time it rains there’s another surge of silt making its way downstream to be trapped by the dam.

    Overall this project would be considerably cheaper, more friendly to the environment, and most likely more efficient than any pumped storage on land. And its not like the sea floor is lacking for real estate, unlike any feasable locations for dams here on land.









  • I put the pic in the comment, it loaded on my side so idk whats up. But basically, I did it in 2 sides. The back side had its roughing and finishing pass done while clamping the billet. The front got its roughing pass again clamping billet. It was supposed to leave .020" thick tabs to keep it in the billet for the finishing pass but they ended up breaking off. So I used the cad drawing to cut an exact pocket of the banana in a piece of wood. The banana fit pretty snuggly into the pocket so I just used some silicone sealant I had on hand to keep it from lifting out during finishing.









  • I think the point the author was trying to make is that the “personal” part of PC is what is dying. the profit model for modern tech is no longer about supplying the best or most useful product but instead exploiting users, either to manipulate them into buying more crap or harvesting their data to sell off to someone else who wants to sell them more crap. Even many of the products we buy these days we don’t really own. Steam just released a policy statement saying that users don’t actually own the games they’ve purchased, but are merely buying a license to access them. If Steam decides not to support a particular title anymore than poof, it’s gone forever from your account. For the most part it seems that if you aren’t running strictly FOSS software or pirating, you can’t really own anything on your PC aside from the hardware. I think the gist of their argument is not that computing has gotten worse, but that while software, hardware, and user experience have massively improved, the exploitation of the user has greatly tainted that progress.
