alt Hacker NewsI dunno if it's that clear cut. In space with a shadowless orbit you get 5x more solar energy per day than the sunniest place on earth. And it's always on, so you don't need batteries. Also, the lack of gravity and weather means that the structures can be a lot more brittle - I imagine something like a gpu on the back of a large thin film solar panel, where the panel also acts as heatsink. Could be pretty cheap!

You can only cool by radiation in space. You may get more energy from the sun but how are you going to get rid of all the heat fast enough?

Yes, you get much more radiation from the sun and other sources. How do you do cooling? Radiators the size of small moons?
Also hard radiation is not something transistors like.

Its not always on. Its only 'always' on if you would orbit the sun which starlink can't do, it has to orbit the earth. This only works in a certain constelation which would create a halo around our planet, without clear understanding what even would do.
The more power you consume, the more power you need to dissipate. These constelations wouldn't be small at all. It would also take a interesting solution to be able to move this heat from very small very intense areas to very big cooling areas. How?
And space is not easy. Space is very very cold which puts a lot of stress on materials. It has radiation. And it has A LOT of microasteroids. Stuff in Space breaks down due to this. You would need to replace all of this stuff regularly with resources from the planet earth.
You would basically just spend a lot of resources throwing a lot of resources out into space. You can't even recycle all of this.
Its still lunatic at our current state of our current system. There is so so much space on our planet. Its ridicoulous
The only reason Musk is saying stuff like this is because he knows there is no market and he needs to keep his system alive
