It's not physically impossible. But the engineering reality isn't promising.
You'd need micro-meter alignment accuracy across the constellation for optical observation. For radio observation it might be possible - but I'm not sure if it would be useful.
Launching complimentary ordinary space-telescopes would also be good PR.
There are enough panels available to do both and there is no overlap in financing for both. So just do every installation that is economically viable, they don't compete for money or panels.
Comparable, I guess. But the result is a lot worse compared to Sonnet for sure. Parts of the example code doesn't make much sense. Meanwhile Sonnet seems to have the latest API of Bevy considered, and mostly makes sense.
How expensive is it to not build a single-purpose building like an office or housing condo in the first place, but a true multipurpose building that can do both well with manageable retooling costs?
Multipurpose anything tends to not work out well. Different use cases have different requirements. Specialization is everywhere, both in nature and in human creations.
Some of that is lost due to regulatory 70% limits during peak times.
Also the rated capacity is for some synthetic sun conditions. I have no idea what's the conversion factor between ideal sun in Germany and the PV rating sun.
Then there is the fact that many installations are explicitly using small converters, not all installations face the same way (east-west setups are a big thing for farms and other large scale setups). I live right next to Germany and getting 80% of your installed capacity is considered optimal.
Increased social equality and mobility, happiness index, etc. are a free bonus I hear, so I guess one could generally recommend that. Depends a bit on where you're coming from, Norway/Switzerland/Iceland are also not EU for example.
And that has been true for centuries, not just since AI.
Allowing intelligence means ceding control over the outcome. And that is often a bigger issue than the actual issue.
