Sky Stack semi-invisible chimney

Didn't go far enough. Wrap the whole tower in reflective sheets. Then you got something...

As if enough birds aren't killed by flying into windows. Very stupid idea and apparently given absolutely no thought to the negatives of such a strategy.

or a trompe l'oeil sky painting might work as well, and not reflect buildings, etc. I kind of like the floating blocks of chimney, though.

@Buellrider - you've clearly never seen a bird hit a window. They drop to the ground, shake their head, and fly away.

christopher, I've disposed of enough that didn't get back up again to know that it's not a rare occurrence that they kill themselves in the process. That being said, if the reflective bands have any sort of pattern that you can only see once you get close, like 3M's reflective tapes, I think the birds would pick up on it in time to avoid collision.

@christopher - birds do not always recover so easily. We just had an incident in our city where nearly a whole flock of Bohemian Waxwings were killed when they flew into a glass art structure in front of the Scouts building.

Not so Christopher. Very many die.

Convex mirror? The birds will see their stretched reflection with plenty of time to avoid the stack.

Think people this is not transparent it is reflective. As the birds get close they will see their reflection think it is an oncoming bird and turn away.

?"...the existential worth of obsolete industrial architecture and infrastructure..."

I guess a solar steam power plant hadn't crossed the 'artists' mind in the first place. It could stand to be taller- then it would need a light at the top...

Actually, the angle reflects the horizon for any observer on the ground, hence the illusion of sky.

From head on (bird's eye) however, the mirrors might partially reflect the ground making the tower look distinctly different and easily avoidable.

Maybe a bit confusing for a helicopter at night though :b
