  • I have a Framework 14 for my school laptop and it really is a great little piece of hardware. Can't wait to see what they come up with next.

  • Tesla’s phantom braking nightmare: lawsuits surge as drivers lose trust in Autopilot

  • Yup, its a terrible design. Every other automaker uses some form of lidar with the cameras, but elon says "HuMaNs DrIvE wItH jUsT eYeS". So we get this bullshit.

  • Tesla’s phantom braking nightmare: lawsuits surge as drivers lose trust in Autopilot

    Jump

  • 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.

  • UK | Fewer than half of young men believe abortion should be legal, poll finds

    Jump

  • The study says they used online polling but didn't elaborate further so who's to say what biases there may or may not be. But generally ipsos does a pretty good job with their polling.

    I do agree that most of these polls tend to end up being nothing burgers, but there has been a recent trend of younger males gravitating towords the right of the political spectrum. I mainly commented to point out that a sample size of 1000 is generally recognized to be large enough for accuracy.

  • A sample size of 1000 people gives a margin of error of only 3%..

  • I feel like if he wanted to he could out right buy half the GOP congress people though. Money holds a lot of political power when the politicians are for sale.

  • Do you think a story that mixes magic with super advanced technology can work?

    Jump

  • The black ocean series does a good job if blending the two together. But it sort of sets them in opposition to each other. Interstellar travel is made possible on futuristic spaceships by using magic to plunge the ship partially into another dimension, shortening the relative distance between stars. But unless the it is specially shielded against it, magic ruins and destroys technology.

  • A German Experiment Proved That Simple Concrete Spheres Make Fantastic Batteries. Now, California Plans To Submerge A 9-Meter Diameter Sphere In The Ocean And Is Already Planning Versions Of 30 Meters

  • You clearly don't understand the basic principles of engineering.

  • 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.

  • That's why I said siphon it from the bottom, a siphon tube going from the bottom to the top would eject the water up and away while still sucking out most of the sediment that had gotten in and settled on the floor of the ball.

  • I don't see silt being as big of a problem here, if the intake is located at the top of the sphere that puts it well away from the seabed. The only silt it could suck in is what's dispersed in the water already, and at 500+ meters there's very little current to stir it up. And if they put the intake on top and siphoned the output from the bottom it would even be relatively self-cleaning.

  • DO NOT MIX BLEACH AND CHLORINE, unless you want die or seriously injure yourself. When bleach is combined with acetic acid it produces chlorine gas, a literal chemical weapon/warcrime. If you want to corrode stainless steel use regular bleach, it does the job just fine.

  • I did not consult that site, the ASME Scaling Banana™ measures 214mm. It was made from a composite 3d scan of 4 different bananas bought from 3 different retailers. Your banana may vary.

  • The Scaling banana contains no Potassium-40, but it does probably have some Aluminum-26 in it. Further testing will be needed to ascertain the actual B.E.D.

  • 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.
