  • If you use approximately the same amount of material as in an aluminum can, you’re already at 3x the weight of an aluminum can. Stainless is also far less malleable and much more brittle than aluminum, so the minimum wall thickness is much higher for steel. Aluminum can walls are 0.11m thick, whereas the minimum wall thickness for stainless steel alloys is around 0.50mm thick. Meaning you’d need around 4.5 times as much material, making the stainless steel can weigh at least 10 times as much as the average 15 gram aluminum can. A 12-pack of soda would weigh 4.5 pounds more. Now imagine how much transporting that extra weight costs.

    Stainless steel is great for reusable stuff, but it’d be impractical at the same scale as aluminum cans.






  • Ok, so you were saying you prefer a privacy focused OS but settle for iOS because it’s simpler. Fair point.

    As far as data collection goes, Google isn’t selling it either. Apple and Google are both collecting your data to assign you to certain demographics. They then sell ad space, and the people that purchase those ads can select the demographic they want it to go to. It’s not ideal, but it’s certainly better than them selling your actual personal data to third parties.

    Imagine you’re breathing through a big straw, and at the other end of the straw is a device that pumps air faster whenever you’re breathing faster, say when you’re running fast. If you turn off power to the pump, you can’t breathe through the straw anymore because the pump isn’t spinning, so you’d need a second straw that opens up only when the pump is off.

    You are the engine, and the pump is the supercharger. When the engine doesn’t need to breathe fast, turning off the supercharger would conserve energy use at the expense of power output. But the design of the pump doesn’t let air bypass it when it’s off, so you’d need to engineer something (overly complex) to do it.
