I've never heard of this before.
Great pics, number 2 is my fav.
I wonder if it's safe for pilots flying nearby? Will it reflect and concentrate the suns light at them?

[Omaroo]

Nah Nettie - although truly parabolic (apparently) it's built to focus just a few short metres in front of the surface. To a plane it's no brighter than glass windows on adjacent buildings.

Someone's got to get a big secondary, some framing / scaffolding and a cherry picker to turn it into a big, fast reflector.

It will be a bit limited in its range of movement but at least it will be put to something useful.

Exactly what I was thinking!

[theodog]

At 10m you wouldn't need any secondary. Just a ladder (that guy's cherry-picker would do!) and a good widefield eyepiece. Head-wobble could be a problem 'though.

Nice images Chris.

Cool!,

I'm going there for lunch today, I might check it out as well as its companion sculpture just across from it......the 25m bottle of Windex ;)

Cheers

Heck, take a loooong fork and some snags, it would be a great solar BBQ !

Just wait till a chopper flies into the focal plane of that beastie :lol::lol: on a sunny day like it is now...
Makes lasers look a tad puny ;)

[Screwdriverone]

It looks really cool, well, hot....
No snags, but a couple of fried crispy seagulls.... It's currently scorching the earth about 10m in front of it at its focal point. Lol :D

[Wavytone]

Hehe the lawn won't last long... guess the museum people didn't think about the consequences of reflections !

That is so dangerous, some baby in a pram or young kids, even adults look into that, and be blinded for life ! ! ! good for a quick free suntan tho : )
