Clearly there is some escape of radioactive martial.

But as has been pointed out numerous times here, the banana scale is flawed because your body regulates the amount of potassium it absorbs, and keeps it away from areas where it could do damage. That's very, very different from something in the environment causing a random wasps nest to experience this amount of exposure.

Because home owners are more sensitive to up front costs. You can see it with lightbulbs. When LEDs first appeared and were expensive, consumers baulked at the idea of a 30 year bulb that cost 5x as much, but businesses could see the long term cost saving from the lower power consumption and reduced maintenance.

Yeah. I think the most likely outcome is that we see sodium used for some applications where a business looks at the cost over the long term, maintenance, that kind of thing. For home batteries people will be buying mostly B grade or used cells. B grade are already cheap and completely fine for that application, and reuse of used cells is ramping up.

Eventually, not today. Maybe not ever, it depends if the economies of scale are enough. A lot of tech has failed to catch on simply because lithium batteries got so cheap so fast.

It will depend what the updates are for. Shoving more ads in the car wouldn't void the warranty if you skipped it, but adjusting the engine parameters to avoid premature wear on some component might. The problem is they won't separate the two things, you have too have the adware to get the genuine fixes.

Shame they seem to be fossil trucks though. Maybe they are working on autonomous charging too. We have had wireless high power, low loss charging in Europe for a while. All it needs to do is park in the right place, and of course the parking area can have lots of assistive markers to make that easier.

More importantly these trucks have Lidar. It has proven essential for safe self driving systems. Cameras alone are inadequate.

You would want pouch cells though. 18650 is just not very space efficient, and only really needed in some very specific applications. That's why most home batteries and most EVs are using pouch cells now.

There are much better options that Tesla Powerwall though. Better capacity, lower price, better reliability.

Such small batteries don't usually need any active cooling either. There isn't much benefit moving to Sodium-Ion, LiFePo cells are cheaper and pretty much ideal for home use.

Do you think the middle men, the importers, actually bother to check all this stuff? Of course they don't, and if it burns you house down and on the off chance that there is enough of an investigation to prove beyond reasonable doubt that the charger they sold caused the fire, they will just refer you to their business insurance or declare bankruptcy.

There are many items for which those kinds of safety issues are not a concern, so there is no point paying a middle man anyway. I recently bought an Android Auto display for an older car. Amazon UK had it for £180, the exact same thing on AliExpress was £23. It's USB 5V powered, so there just isn't enough energy there to actually cause a fire.

There are some things where it's worth getting a branded version from a company with a decent reputation, but mostly it's just someone adding a 1000% mark up and doing no checks themselves.

You can't bring outside food onto airliners where you live?

I usually bring a sandwich or something on long haul flights, instead of the meals that they offer.

I was about to say, what possible technical means could they have to implement such a feature that didn't involve some serious hacking? GNSS won't work in many datacentres or when the device is powered down, and is easy to block. Cellular is also easy to spoof and would require a whole cellular modem and antenna. And even once they figure out where they are, how are they going to get that data out and back to the US?

Just wait until it becomes mandatory. The party of Small Government (TM) really wants to regulate your healthcare, especially if you are a woman or transgender.
