Niagara Generator

Niagara Generator was built by Nikola Tesla at Niagara Falls. It powered an entire city.

When Nikola Tesla saw the Niagara Falls for the first time he was inspired to built his Niagara Generator. In 1903, he held a presentation for the inventors, asking for an investment of 50000 dollars, but they were not willing to pay him. (TV: Nikola Tesla's Night of Terror)
