I think we should wait to see how the first satellite data centre works out. It seems fairly unlikely that it could be practical. It seems kind of nuts...
>Reflect Orbital, a US start-up, aims to launch a constellation of very large mirror-like satellites to provide sunlight at night, with reflected beams that span at least five kilometres on Earth's surface.
Straight up nuts with no practical value, even if it did work out.
I can think of several practical uses. It would be very useful immediately after a disaster. Lighting up the night would make search & rescue much more effective. It would also allow for more solar power generation in an area, reducing pollution. Extra light at high latitudes in the winter would reduce seasonal depression.
Are they worth the cost/tradeoffs? I don’t know. But there is practical value to lighting up the night.
