Tesla's workshops still exist, though they are boarded up and in somewhat of a stasis right now.
"At the dawn of the 20th century, Nikola Tesla wanted to save the world from fuel dependency. Now, an Internet cartoonist wants to save Tesla's last remaining laboratory as a tribute to the futurist inventor.
The structure, a 94-by-94-foot building, was the location where Tesla hoped to develop wireless communications and clean, free energy for everyone in the early 1900s. He moved his operation to the Wardenclyffe Tower in Shoreham, New York, in 1902 -- so named because of a 187-foot tower rising from the ground (as well as being sunk 120 feet below it) that was to be one of the great transmitters for his wireless energy dream."
