Such as? Military in the next 100 years will be drone / remote based, they have IR / night vision and soon to be fully automated. Sunlight can be handy for humans but for decades now the only ones that would benefit from it would be foot soldiers, and they're like the last resort (for western forces anyway).

Daylight helps you just as much as your enemy. We've got plenty of cutting edge night vision and thermal imaging devices for humans and radar on vehicles. The Army's 160th helicopter regiment can fly nap of the earth on a moonless night. Satellite-based Synthetic Aperture Radar can pickup human sized objects during a pass and can switch to sub-centimeter resolution in finer modes. If anything, the military prefers fighting at night because of the advantage it holds.

Yes, think about how this can be weaponized. Illuminate an area? Or, focus that energy on a single point and you've got sun powered space lasers?

Here's a ninety thousand lumen floodlight: https://www.kaufland.de/product/500729350/?search_value=stad...

And a satellite isn't going to provide "hours" of extra light unless it's a very much higher orbit than current proposals. At 600 km altitude, you're talking 20-30 minutes even with an unbounded number of satellites (and 10-15 minutes when you've only got a few satellites). Same reason as sunset itself happens: Earth just gets in the way.

But they'd be competing with the old fashioned stadium lights. I don't think they would be cheaper somehow.

Opposed to holding the event during the earth's orientation towards the sun, aka daytime? Someone should tell the gala and event organizers about this idea of daytime.

How huge is it on a continuous basis? Ii's low earth orbit, so only available for a few hours after sunset, AND requires a new satellite in position every 15 min. So for two hours extra illumination you need to support a couple DOZEN satellites, costs of build, launch, control, and maintenance. Even with 100% bookings —every night— it is dubious finances. Seems much more like a scheme to generate a money flow from meme-investors they can siphon off into their pockets then oops, it fails.

If this is somehow an actual problem, it is far more solvable with tethered blimps or drones, battery pack in a container on a truck, a spool of wire, and light banks as big as you want. AND that isn't subject to clouds (but would be subject to high winds, which would also be more likely to cancel/postpone the event than clouds).

Meanwhile, they go beyond the already massive disturbance of existing terrestrial lighting and overwhelmingly screw up the biologically critical light signals used by every plant, insect, animal, and human in the zone, and do it at multi-kilometer scale.

Edit: Even if the revenue potential is actually huge, it is no justification. For any intelligent person, the actual sponsorship message will be "Tonight's lighting brought to you by [Insert_Company_From_Which_I_Will_Never_Buy_Anything_Again]

This level of stupidity is beyond evil — the kind of lunacy to make a good argument that humans should not exist.

Frankly I don't see this happening before the year of the Depend Adult Undergarment

Rescue operations, etc...

I saw a presentation by one of the founders where he talked about several use cases where the benefit is just phenomenal.

They don't fool me for a second, however. The end goal of this is to build a weapon that can fry people/places on demand (but only the bad guys, of course).
