LOL. Where in the article does it say that the sign had "separate electric utility meter and power supply" from the building and would continue to function even if the power went out to the building?
Are you for real?
From 1953, the infrastructure was in place on the TSBD roof for a devoted high voltage power line on its own independent circuit and utility meter
At least you are backing off the claim that this sign was battery powered.
I never claimed that. That was Walt. I asked you how you knew it wasn't. You didn't know -- you just assumed it. Tom to his credit bailed you out.
The article cited also does not address the Hertz sign but a sign placed there a decade earlier. Simply saying it had a separate meter does not mean the power would have been on to the sign if the power source were cut to the entire building.
Sure, but not only are you convinced for no good reason that the power to the sign was dependent on the power to the building, but you also somehow convinced yourself that somebody argued that power was cut to the entire building.
It does not mean it was "completely independent of any power inside the building".
Do you know how electric meters work? For them to be metered separately, they have to be isolated.
Coming from Mr. Everything is an Assumption that it a very humorous highlighting both your dishonesty and stupidity.
Like clockwork. If all else fails, start flinging insults.
