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.

It doesn't work out anyway. If you work out how much light these satellites can reflect it is practically nothing and certainly not economically viable. The company seems to be little more than a way to extract money from fools.

No. Lighting up the night is an abomination. Reflect Orbital can go fuck themselves.
