I have to say this is perhaps one of my favourite CCC talks. Interesting subject matter, novel technical problems and solutions, story narrated at speed and with just enough information to fill in typical knowledge gaps, and on top of all of that there's slides and answers ready to go for random questions from the audience. Wonderful job, PistonMiner!

The extra slides in the Q and A were a hoot. Super impressive preparation and anticipation by the speaker.

For many years I have wanted to make an "Earth Sat" that is isolated as though it were in orbit, but is here on Earth. There's also the possibility of high altitude balloons but those have a finite life. Or might get shot down.

From all I understand, almost all SATs, especially LEO ones have a finite life as well. Starlink ones will stay up about 5 years and then de-orbit themselves; but even without de-orbiting itself the (very low) atmospheric drag would take it down eventually after the fuel to keep it in orbit runs out

Any idea why they only want Starlink to stay up for 5 years?

It's more a physical limitation. Low Earth Orbit satellites (LEO) are closer to the atmosphere and have some friction with it, slowing it down and then gravity does its job.

To stay longer you would need less heavier satellites, with more fuel to correct their trajectory. Or fly higher and have more latency.

5 years is just a good compromise.

I also thought this!
