  • No this is for everything including personal devices. It’s very simple to just say it’s like everyone listening to their phone on speakerphone and the louder it is and the closer you are the more distracting it is to you. Everyone can use it but the more crowded it is the more problems you have. If everyone uses it responsibly then everyone can use it and it’s fine. That’s why the FCC sets power limits because otherwise you could jack up the signal with a ton of power and no one else can hear anything. For signals it is only the same frequency that interferes with each other but all the space comsats use the same popular KU band so they have to share nicely.

  • It’s more about a minimum of weight or pressure that affects it. So the higher the pressure the more likely it is to flex the road where a small vehicle with light pressure might not make it flex at all. The heavier it is the more the weight will flex the subsurface and cause more damage.

    “To give you an example of that impact, let’s do a quick calculation. Here in New Zealand, the heaviest vehicle allowed on (some of) our roads is the 50MAX truck. It has nine axles and a total weight of 50 tonnes, so the load-per-axle is 5.55 tonnes. The best-selling car in NZ in 2022 was the Mitsubishi Outlander. It weighs 1.76 tonnes, so its load-per axle is 0.88 tonnes. The fourth-power law says that to calculate the relative stress that these two vehicles apply to a road, you take the ratio of their loads-per-axle and raise the result to the fourth power. In this case, (5.55 / 0.88)4 = 1582. In practical terms, it means that a 50MAX truck applies as much stress to a road as 1,582 cars (or quite literally billions of bicycles)”







  • No I mean it wouldn’t be possible to make them here, if you tried to build a series of factories they would not have enough workers. It’s like an order of magnitude scale difference, the largest industrial plant in the US is 30k workers and in China the big one for iPhones is 350k. And that is 350k people working super long hours. Even in China labor isn’t plentiful anymore, there is shortages of labor in the coastal areas. You try to hire a staffing firm and tell them you want 300k skilled workers in a city and they’ll just laugh at you.
