Wardenclyffe Tower (1901 –1917) also known as the Tesla Tower, was an early wireless transmission tower designed by Nikola Tesla and intended for commercial trans-Atlantic wireless telephony, broadcasting, and proof-of-concept demonstrations of wireless power transmission. It was never fully operational, and the tower was demolished in 1917.
Tesla's comments about wireless devices:
"As soon as [the Wardenclyffe facility is] completed, it will be possible for a business man in New York to dictate instructions, and have them instantly appear in type at his office in London or elsewhere.
He will be able to call up, from his desk, and talk to any telephone subscriber on the globe, without any change whatever in the existing equipment.
An inexpensive instrument, not bigger than a watch, will enable its bearer to hear anywhere, on sea or land, music or song, the speech of a political leader, the address of an eminent man of science, or the sermon of an eloquent clergyman, delivered in some other place, however distant. In the same manner any picture, character, drawing, or print can be transferred from one to another place ..." –

The fist versio (at left) was created in 2011 and in my opinion, the piece was prone to break due some assemblage issues.
So, the 2nd version was built in a more robust body.
It fell on the ground in an art exhibit. Nothing could be done...
Then the 3rd version came, the piece was almost totally redone.
And I believe, it is the definitive one.
