Not unlike looking at a city from a distance at night.

I think it's up to the Aboriginal people to decide if it's a good thing to do. What do they think? I think it will look about the same no matter where you put it.

Classic, didn't do well in school so he became an artist? SQR of 250000 is 500, And area 1000 by 1000 meters means the lights are on average 2 meters apart.
The images shown here suggest a much higher density. Taking a stab at it, more like 0.5 meter on average. That would need 40 million of those lights.
Never mind. That is only 16 times more. With 250000 lights this initiative will look decidedly pathetic. Maybe he should stick to an area 100 x 100 meters. Or even better, head back to primary school.

Awful idea. We need LESS light pollution, not more!

I was doing Paul's back-of-the-envelope as I was reading and had to add in the rubbish content. With 41 men working 7 days/week it would take ~45 days to install/dismantle this rubbish. Because of the sun you would have to work in the evenings so that will add to the amount of time.
The actual working lifespan of the flowers is likely to be closer to just a few days. Has he has tested his prototypes in the extreme heat/cold, wind, dust and other factors of Uluru. These bloody flowers would need to be made of NASA quality materials just to survive the environment long enough to light up.
Another factor is the number of water bottles, snack bags, granola bar wrappers and other rubbish that will be left behind with the flowers they can't find when trying to clean up.
Essentially the artist is asking for permission to turn Uluru into his personal rubbish tip.

Pollution is never art, and to suggest that such a project would be "leaving a minimal carbon footprint" is dangerously naive - people aren't going to swim to Australia and walk to Uluru to see this. The photoshop rendering of the idea looks cool enough, and won't tax the environment on such a massive scale.

What a waste of time, money, energy and resources...and the carbon footprint will be huge...why do we generate toy rubbish like this when all the resources are running out???? There is a name for it but can't remember what it's called...Anyway the Dingo's 'll love it something to wee against in the dark...too much time on somebodies hands me thinks :-)

The amount of commerce flow may provide a benefit to the region with lasting effects if done wisely. A similar example is the EMP project in Seattle and it continues to receive investment as a place to visit.

Also, whoever owns the project is responsible for the upkeep, security, and maintenance.

Why doesn't he use those self-charging garden lights that all the DIY stores sell? It would be a good way to get rid of them as well, and I'm sure a company would be willing to sponsor him. WHat happens to the fibre optic wires and recycles acrylic after this project has bored the world?
@ ZipZapRap couldn't agree more...
