You make a concave surface pointing down to the ground and cover it in glass, at certain times the sun will shine on this reflective surface.



What will happen on the ground where this concave surface points at?

Too much plastic used in modern cars.

You would think that someone might have done the math here and come up with the possibility that sunlight might get focussed too tightly and create trouble.

Thinking about it. It's probably down to 'ealth 'nd Safety in schools, they have probably banned experiments with shaped glass, and what happens when light is reflected and refracted etc.

And so students no longer feel focused sunlight on the back of their necks.

Lack of common sense and forethought.

I had to grimace when I heard a quote from the builder/designer earlier today - it went along the lines "In a few days time the sun will have moved and the problem will have gone away"....
I just hope that something is done about those windows, and pretty quickly - I'm sure the average school boy of my generation could lend them a hand ;-)

The illuminated spot.


The "hot spot" on Eastcheap, in London

The car wasn't the only casualty. There have also been reports of a smouldering bicycle seat, singed fabric and blistered paintwork.

The article I saw on Yahoo mentioned blistered paint on shop doors, scorched carpets, and melted pavement.

Who ever designed it shouuld be made to park where the sun is focused and made to move his car all day long to follow the beam.

There are reports that the designer has had previous occurrences of this problem, a hotel in Las Vegas has been mentioned.

The excuse for this shape is to increase the floor area where rents are higher.

He needs to find a better way to do it, then. Maybe keep the windows vertical and step them out at each level. Actually, I didn't look very closely; is this actually curved glass? If so, would just replacing it with flat glass fix the problem?

Was it Steven Colbert I heard comment on this, to the effect of: "[explains the problem] Who knew? There's actually sunshine in London."

Some so called architects are just buffoons. Take the Millennium bridge across the Thames in London, designed by Sir Norman Foster, now apparently Lord Foster of Thames Bank.

Londoners nicknamed the bridge the "Wobbly Bridge" after participants in a charity walk on behalf of Save the Children to open the bridge felt an unexpected and, for some, uncomfortable swaying motion on the first two days after the bridge opened. The bridge was closed later that day, and after two days of limited access the bridge was closed for almost two years while modifications were made to eliminate the wobble entirely. It reopened in 2002.

The wobble was attributed to an under-researched phenomenon whereby pedestrians crossing a bridge that has a lateral sway have an unconscious tendency to match their footsteps to the sway, thereby exacerbating the sway. The tendency of a suspension bridge to sway when troops march over it in step was well known, which is why troops are required to break step when crossing such a bridge.

I wouldn't set foot in any building that he had anything to do with.

Given the shape of the building flat glass wouldn't be much better than curved glass. Flat glass would still be mirrors, sitting on a parabolic surface. One solution would be to use an anti-glare coating as used on lenses - just think how "dead" a good Cannon or Nikon lens looks.

How do you increase floor area with a concave?

Wider at the top & bottom than in the middle - the higher floors are wider than the ones below - more floor space for large suites with lots of windows, and the penthouses.

Thnaks, I was thinking the whole front being concave. I get it now.

I suspected you had not seen the pictures. On both my P4/XP boxes, the browser home page is Yahoo, and for the past couple of days they've had an article about this building posted in their newsfeed.

I didnt look in the link wich shows a much better picture. From the OP pic, I just thought it was concave from side to side not top to bottom also.
