Just curious as to what frequency Tesla used to send his electricity from Niagara Falls. We have a small wager going that it was less than 60 Hz.

At the start of 1897 there were some 300 electrical power generating plants operating here in the United States. The most important of these belonged to the Niagara Falls Power Company who had transmitted 1000 horse power to Buffalo, New York on November 16, 1896. The original AC power plant, dubbed the Edward Dean Adams Hydro-Electric Power Station Number One, was designed to operate at a frequency of 25 cycles per second (Hz). The current was used for the propulsion of electric street cars. A subsequent expansion of the Niagara Falls facility included a conversion to the now familiar 60 Hz.
