Forget SimCity the Pentagon should be forced to sit down and read the 1980s edition of the Eagle comic.

I can't remember the name but there was a storyline where a brand new orbital powerstation was turned on and the moment the power beam reached the ground it effected the atmosphere and rendered it impossible to generate electricity. After many months of apocaliptic warrior stuff, involving steam trains and diesel powered Chieftan tanks in and around the tower of london, it was only the timely arrival a comet that destroyed the orbital station that saved civilisation..... actually sounds like it could be fun turn it on!
