I thought this was interesting.


Nautilus 1906

We discussed the Worlds Fair searchlight in the early days of the thread, but I don't remember discussing how it was powered. (maybe I just forgot)


below / from GIZMODO

"When running at 200 amperes—a current generated by a Pelton water wheel in a nearby canyon—the carbon arc lamp burned with the intensity
of 90,000 to 100,000 candles. A massive reflecting lens mirror magnified that blaze to 375 million candlepower.
"


Does anyone know in which canyon this Pelton water wheel was located?

#2: location of searchlight in relation to the observatory:


ebay find [dated: 1908]

Is this view about 1,500 ft from the observatory?

-was the searchlight in this area in the foreground / where the photographer was standing?









Oh, and one more thing



Am I the only one who didn't know the observatory dome was initially covered in canvas?
