A good litmus test for good city location is whether or not melting objects/burns from touching objects is a daily concern

Yeah, I agree: the bug here is humans building giant cities in the desert.

Like southern California?

Forget beta. Apple's production iPhones go into thermal shutdown several times a year for me where I live. Most recently, yesterday. You can tell it's getting close because the screen will dim. The tech bubble has never understood that the rest of the planet doesn't have the same weather as San Francisco.

Yup, it's always incredible to see how myopic tge tech bubble is - starting with software that couldn't handle East Coast US 5-digit ZIP (postal) codes that begin with "0". Google Maps never shows the highway exit # until you're nearly there, but that's all we use on the East Coast, since there are many old roads that run parallel to the highways for many miles, so telling me to "get off at Rt110" is hopelessly ambig…

I have the opposite issue; Google will tell me the exit number on highways that don't have exit numbers posted.

The Ars Technica version of this story [1] has more detail. The tl;dr is that Starlink dishes have an upper limit of 50°C and a lower limit of -30°C. While these limits are fine for consumer electronics used indoors, they're obviously inappropriate for outdoor electronics. [1]: https://arstechnica.com/information-technology/2021/06/starl...

> they're obviously inappropriate They're unfortunately constraints, but for 95% of people they're workable constraints. If there are difficult problems with bumping these limits (I have no clue), it could just become part of the market definition.

Only if you're counting people who live in San Francisco and other similarly temperate climates.

I live in Minnesota. Last week, the high temperature, in the shade, was about 40°C. A device in the sun would easily see its temperature exceed 50°C. In the winter, overnight lows can go to -40°C. An outdoor device with thermal limits of -30°C to +50°C is not fit for purpose in many parts of the Midwest.

Parting Shot: "To all beta testers using Starlink this summer, better come up with a dish heat management system or else face no connectivity. Not surprising, considering this is a company owned by Elon Musk."

Well it is a beta test after all. This is when the design gets a real life shakedown.

I agree with you in general, but despite my not being a rocket scientist, i know for sure 50°C is not an OK limit for outdoor stuff on many parts of the planet. It's like Outdoors Electronics 101 so not exactly something to test for in a beta.

Two things: first, Apple is headquartered in Cupertino, which gets quite a bit warmer than San Francisco. Second, I've seen phones overheat and shut down in the summer in SF. This isn't a bubble thing; this is a company prioritizing miniaturization over proper functioning. Form over function.

95% of which group of people?

How much energy does it use?

110W peak usage. I've seen wifi hotspots use this much and they don't have to connect to space. Is this really "energy pig" level of usage for space based communications? My former experience was with gimbled / gyro pointing dishes which were very energy intensive by comparison. 100W and little physical movement would have been considered very efficiant. How do other space com platforms handle deployment / install of…

According to international standards, your wifi antennas should have a maximum of 0.1/0.2W power (up to 4W for some specific 5Ghz frequencies). Wifi router hardware is really basic, you need something as powerful as a computer from the late 90s... which on todays hardware runs on a few watts. Something like a rpi is really beefy for a home router.

So 100W may not be a big deal if you have an abundance of electricity around. But on the order of energy you can produce yourself, it's quite a lot.

Otherwise potential starlink customers.

Like most stats, it is made up.
