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.

"Even considering the improvements possible... the gas
turbine [jet] could hardly be considered a feasible application
to airplanes because of the difficulty of complying with the
stringent weight requirements."

"It may not be possible to build a vehicle with single-stage-
to-orbit capability in the mid 1990s."
