Story in the news today about the plastic bits on a Jag getting melted by the rays reflected from a new tower block in London.
Every 14 year old gets taught that if you have a concave mirror it will focus light on a particular spot, where, exactly, depending on the curvature of the mirror. So if you build a big shiny building with a concave wall, it's going to function as a mirror, right? They seem to be trying to blame the angle of the sun, which is also a somewhat predictable scientific phenomenon. Or did they do the calculations and decide it would be OK because the focal point was in mid air somewhere and forget that the angle of the sun changes?
This got past lots of architects and planners, some of whom, surely, passed their GCSE in science?
