Že by měl Empire State Building aktivní hromosvod?
Silně pochybuji. To by o tom něco na ofic. stránkách ESB napsali. Cituji odtamtud:
"The entire building is constructed as a lightning rod -- lightning strikes the top and is dissipated by the intricate steel structure into the ground -- the safeguard is not merely a rod, but the building itself is essentially an enormous set of steel cages -- the energy is divided and subdivided.
Yes, the building is designed to serve as a lightning rod for the surrounding area - it is struck by lightning about 100 times per year."
