- I hope everybody here recognized the obsurdity of thinking that a 20
- meter mirror could "extend the daylight hours of the Siberian regions."
- 'The Guardian' clearly doesn't. (Typical newspaper science writing.)
- The most the mirror would do is make a bright spot in the sky.

- But, as my .sig notes, journalists don't have a monopoly on stupidity.
