Comment: It appears an unusual amount of buildings have been catching fire or exploding lately. In Earth Changes and the Human-Cosmic Connection, Pierre Lescaudron presents the possibility that certain types of buildings or factories can act as attractors for dramatic electrical discharges, whether 'sparked' by incoming comet fragments or atmospheric electrical conditions. So could something similar be responsible for some of these fires?
