Funny how if it's someone we like, they used it. But if it's someone we don't like, they abused it.

Wasn't there a scene in Minority Report where the star was trying to run away from the authorities he kept getting his iris scanned by electronic billboards and signs as he ran through the crowded shopping plaza?

IIRC the advertisements and announcements that played started customizing themselves indicating they'd identified a criminal and showing is face and profile?

Oh, also I have a pair of Coofandy 'business' drawstring pants. They're absolutely fucking comfortable and fit well.

"Yutianhome"

See there is the trick, find companies out there that actually TRY to be human sounding instead of just random grouping of letters and numbers. This is usually the first sign that you're more likely to encounter legit yet cheap product. Vevor is... eh kinda easy to remember and their product listing prices look more like what an actual manufacturer would be charging to retailers buying their stock.

it always annoys me to see announcements of a correlation being described as a cause-and-effect.

Whenever I see cause-and-effect stated without them being clearly distinguished, I always ask myself "could they have the cause and effect flipped around?"

Maybe people that have "younger brains" are much more likely to be in the group that has learned another language recently?"

That seems to be much more likely than the stated order, since people with more youthful minds would be more likely to be learning new languages than others with older, less-flexible minds?

Or stated another way, "younger minds encourage multi-lingual" rather than "multi-lingual encourages younger minds".

The company I work with can easily ramp up satellite production to the scale required. It's one of the reasons I got hired, my extensive manufacturing experience in electronics and solar and power systems pairs perfectly with the requirements.

Perhaps the IEEE should spend some actual time with the companies that already have some of this hardware in orbit, with more going up soon.

I have seen satellite dishes at the base of isolated cell towers, though I have no idea what they were being used for.

One big drawback for satellite networking is the delay it adds to the transmissions, to travel up to the satellite and get sent back down to a ground station. This delay probably wouldn't be tolerated by a cell phone user, especially if they were talking to another cell phone which would double the delay a second time.

There's also a bandwidth issue at the satellite, if you want to do that with hundreds of thousands of towers there's just no way to have that amount of bandwidth even from a cluster of satellites. The bandwidth problem isn't one of data rate, its one of needing to be able to communicate with the ground on so many different channels because of all the towers, and having satellites at many different geostationary locations. (that's what Musk is trying to do with launching this absurd number of starlink satellites)

High data rate meshing requires directional antennas pointed at other nodes, unlike the more broad-beamed bay antennas the towers use for cellular access. Adding several dishes and a bunch of expensive hardware to each tower would dramatically increase tower cost and maintenance.

It's much cheaper to just run a network drop off a nearby pole or trench a line to the nearest fiber vault. Even the towers out along the open highways tend to get fiber trenched to them rather than dishes networking them together over the air.

Here in the USA anyway, cellular service has been considered "critical infrastructure" for quite some time now, mostly due to the decline of landlines. 9-1-1 having high availability has been legally required for a long time, and those requirements shifted to the cellular network as people ditched their land-lines for cell phones at home. So all the towers have short-term (15+ minute) UPS's and a gas generator that auto starts, with requirements to run periodic tests.

The other part of it though is the towers nowadays require internet access to function. We had a massive storm system move through the area a few years ago with close to tornado-speed "straight-line winds" that took out a huge amount of above-ground internet infrastructure, rendering cell towers functionally disabled despite giving out full bars. There were a few lines still up but everyone's home internet was either down or spotty, and it was hard to get a cell call to connect. Was llke that for 2-3 weeks, really annoying.

So, power's not the only thing that needs to be protected to keep cellular service working.

oh I guess I really hadn't thought about heating needs. The batteries generate heat when being charged or discharged so I was just assuming they never really would need external heating.

I live in Iowa, and I've heard some pretty brutal accounts of bad EV performance when it gets really cold here. All rechargeable batteries perform poorly in the cold though, I remember NiCD batteries being absolutely terrible in the cold.

incorporate advanced refrigerant-based and liquid cooling circuits

That's nothing new, AFAIK, all EVs already do this.

Apparently they're homeless because Microsoft didn't pay out so getting out more is probably the last thing on their mind since mission accomplished - they're outside already.

75kW is a lot of heat. Think about the heat from a 100w light bulb (99% of which is heat) Now stack 750 of them and feel the sun!

Also, this car isn't flying down the freeway, forcing massive amounts of air through the radiator to cool it. This one's parked, and only has the forced airflow of the radiator's fan to keep it from melting into goo.

But that 75kW is talking about the charger, which may be able to handle more than one vehicle, or larger vehicles like EV trucks and busses, so the number is likely a lot smaller for the average EV car. But still, lotta heat!

Usually rapid chargers produce quite a bit of heat in the battery, how are they managing this?

I assume the EV stays turned on and runs a cooling loop and blasts hot air out a radiator somewhere, but even that has to have its limits?

"It was hard to figure out how do you balance getting ready to go, not go, all that stuff,"

That must be pretty stressful... "hey you MIGHT be going to space in a few months, but maybe not! Plan accordingly!"

Those are some pretty radically different options there, going to space and staying on earth really aren't two separate scenarios that are easy to come up with a flexible plan that can cover both.

I recall Neil saying he wasn't able to get life insurance when he was flying the experimental planes, and so NASA had to cover him. I wonder how that works with astronauts? I can just imagine making that phone call to your insurance company.... heeeey say I'm going to be flying around the moon next month so... "thank you for letting us know, we've suspended your insurance coverage for the next two months". Gee thanks.
