History

Construction

Tesla began planning theWardenclyffe Tower facility ca.1898 and in 1901 constructionbegan on the land near LongIsland Sound. Architect StanfordWhite designed the Wardenclyffefacility main building. The towerwas designed by W.D. Crow, anassociate of White. Funding forTesla's project was provided byinfluential industrialists andother venture capitalists. Theproject was initially backed by the wealthy J. P.Morgan who had invested $150,000 in the

facility (more than $3 million in 2009 dollars).[1]

In June 1902, Tesla moved his laboratoryoperations from his West Houston Streetlaboratory to Wardenclyffe.

The project ran into many problems.[6]

Financiers began investing in GuglielmoMarconi's system which started regulartransatlantic transmission in 1903 and seemedto be doing it with far less expensive equipment.By 1903 Tesla's project, still under constructiondue to numerous design changes, ran out ofmoney and Morgan declined to fund it anyfurther. Some in the press began turning against

the project claiming it was a hoax.[7] Tesla triedto generate more interest in Wardenclyffe byrevealing its ability to transmit wireless electricity, but Morgan was notinterested, and the 1903 "rich man's panic" on Wall Street dried up any further

investment.[8][9][10] By July 1904, Morgan (and the other investors) finally decidedthey would not provide any additional financing. In May 1905, Tesla's patents onalternating current motors and other methods of power transmission expired,halting royalty payments and causing a severe reduction of funding to theWardenclyffe Tower. In an attempt to find alternative funding Tesla advertised theservices of the Wardenclyffe facility but he was met with little success. By thistime Tesla had also designed the Tesla turbine at Wardenclyffe and producedTesla coils for sale to various businesses.

By 1905, since Tesla could not find any more backers, most of the site's activityhad to be shut down. Employees were laid off in 1906, but parts of the buildingremained in use until 1907. In 1908, the property was foreclosed for the firsttime. Tesla procured a new mortgage from George C. Boldt, proprietor of theWaldorf-Astoria Hotel. The facility was partially abandoned around 1911, and thetower structure deteriorated. Between 1912 and 1915, Tesla's finances unraveled,and when the funders wanted to know how they were going to recapture theirinvestments, Tesla was unable to give satisfactory answers. Newspaper headlinesof the time labeled it "Tesla's million-dollar folly." The facility's main building wasbreached and vandalized around this time. Collapse of the Wardenclyffe projectmay have contributed to the mental breakdown Tesla experienced during thisperiod. Coupled to the personal tragedy of Wardenclyffe was the 1895 fire at 35South 5th Avenue, New York, in the building which housed Tesla's laboratory. Inthis fire, he lost much of his equipment, notes and documents. This put Tesla intoa state of severe depression.

Post-Tesla era

In 1915, legal ownership of the Wardenclyffe property was transferred to GeorgeBoldt of the Waldorf-Astoria Hotel for a $20,000 debt (about $400,000 in 2009

dollars).[1] In July 4, 1917, during World War I, the tower was demolished withdynamite on orders of the United States Government which feared German spieswere using it and that it could be used as a landmark for German submarines.[11][12] Tesla was not in New York during the tower's destruction.[citation needed]

George Boldt wished to make the property available for sale. On April 20, 1922,Tesla lost an appeal of judgment versus his backers in the second foreclosure.This effectively locked Tesla out of any future development of the facility. In 1925,the property ownership was transferred to Walter L. Johnson of Brooklyn. OnMarch 6, 1939, Plantacres, Inc. purchased the facility's land and subsequentlyleased it to Peerless Photo Products, Inc. AGFA Corporation bought the propertyfrom Peerless and sold the property to a non profit organization supported by TheOatmeal in the year 2013. The main building remains standing to this day. Agfaused the site from 1969 to 1992 then closed the facility. The site has undergone afinal cleanup of waste produced during its Photo Products era. The clean up wasconducted under the scrutiny of the New York State Department of Environmental

cadmium.[1][13][14]

Preservation efforts

On February 14, 1967, the nonprofit public benefit corporation Brookhaven TownHistorical Trust was established. It selected the Wardenclyffe facility to bedesignated as a historic site and as the first site to be preserved by the Trust onMarch 3, 1967. The Brookhaven Town Historic Trust was rescinded by resolutionon February 1, 1972. There were never any appointments made after a legal

opinion was received; it was never set up properly.[15] On July 7, 1976, a plaquefrom Yugoslavia was installed by representatives from Brookhaven National

Laboratory[16] near the entrance of the building. It reads:[17]

Designation of the structure as a National Landmark is awaiting completion of

plant decommissioning activities by its present owner.[19]

In 1976, an application was filed to nominate the main building for listing on the

National Register of Historic Places (NRHP). It failed to get approval. The TeslaWardenclyffe Project, Inc. was established in 1994 for the purpose of seekingplacement of the Wardenclyffe laboratory-office building and the Tesla towerfoundation on both the New York State and NRHP. Its mission is the preservationand adaptive reuse of Wardenclyffe, the century-old laboratory of electrical

pioneer Nikola Tesla located in Shoreham, Long Island, New York.[20] In October1994, a second application for formal nomination was filed. The New York StateOffice of Parks, Recreation and Historic Preservation conducted inspections anddetermined the facility meets New York State criteria for historic designation. Asecond visit was made on February 25, 2009. The site cannot be registered until itis nominated by a willing owner.

Main article: Tesla Science Center at Wardenclyffe

In August 2012, concerned about an apparent offer to purchase the site anddevelop it for commercial use, The Oatmeal launched a fundraiser for the TeslaScience Center to raise $1.7 million in order to purchase the property, with thehope of eventually building a museum on the grounds. The state of New York

agreed to match donations up to half that amount.[21][22][23] As of October 3,2012, the goal of $850,000 had been reached in just over six days after a $33,333donation from the producers of the Tesla film Fragments From Olympus - TheVision of Nikola Tesla put them over the top. A total of $1.37 million was donated,the matching grant from the State of New York brings the total collected to over$2.2 million. The surplus will be used to fund the cleaning and restoration of theproperty. Tesla, Wardenclyffe and the museum fundraising effort will be thesubject of a new documentary being produced called Tower to the People - Tesla's

Dream at Wardenclyffe Continues.[24][25] On 2 May 2013, the group announcedthat the site had been acquired. Proceedings for a museum on the site will occurin the years to come.

Facility grounds

Wardenclyffe is located near the Shoreham Post Office and Shoreham Fire Houseon Route 25A in Shoreham, Long Island, New York. Wardenclyffe was divided intotwo main sections. The tower, which was located in the back, and the mainbuilding compose the entire facility grounds. At one time the property was about

200 acres (0.81 km2). Now it consists of slightly less than 16 acres (65,000 m2).

The wood-framed tower was 186 feet (57 m) tall and the cupola 68 feet (21 m) indiameter. It had a 55-ton steel (some report it was a better conducting material,such as copper) hemispherical structure at the top (referred to as a cupola).Designed by one of Stanford White's associates, the structure was such as to

Beneath the tower, a shaft sank 120feet (37 m) into the ground. Sixteen iron pipeswere placed one length after another 300additional feet (94.4 m) in order for themachine, in Tesla's words, "to have a grip on the

earth so the whole of this globe can quiver."[26]

The main building occupied the rest of thefacility grounds. It included a laboratory area,instrument room, boiler room, generator roomand machine shop. Inside the main building,there were electromechanical devices, electrical generators, electricaltransformers, glass blowing equipment, X-ray devices, Tesla coils, a remotecontrolled boat, cases with bulbs and tubes, wires, cables, a library, and an office.It was constructed in the style of the Italian Renaissance.

Telefunken Station

After Wardenclyffe, Tesla built the Telefunken Wireless on the South Shore ofLong Island. Some of what he wanted to achieve at Wardenclyffe was achievedwith the Telefunken Wireless. In West Sayville, Long Island, New York, Teslaassisted in the building of three 600-foot (180 m) radio towers, creating thewestern wireless communication station in a North America and Europe network.

Tesla quotations

"As soon as [the Wardenclyffe facility is] completed, it will be possible for abusiness man in New York to dictate instructions, and have them instantlyappear 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 anychange whatever in the existing equipment. An inexpensive instrument, notbigger 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 eminentman of science, or the sermon of an eloquent clergyman, delivered in someother place, however distant. In the same manner any picture, character,drawing, or print can be transferred from one to another place ..." – "TheFuture of the Wireless Art," Wireless Telegraphy and Telephony, 1908, pg.67–71.

Transmission of electrical energy without wires

An electric current flowing through a conductorcarries electrical energy. The body of the earthis an electrical conductor, nearly spherical inshape, insulated in space. It possesses anelectric charge relative to the upper atmospherebeginning at about 50 kilometers elevation.When a second body, directly adjacent to Earth,is charged and discharged in rapid successionthis causes an equivalent variation of Earth'selectrostatic charge resulting in the passage ofelectric current through the ground.

The Tesla coil transmitter, both the single anddual tower forms, is an electrical machinespecifically designed to create as large adisplacement as possible of Earth's electriccharge. It does this by alternately charging anddischarging the oscillator's elevated terminalcapacitance at a specific frequency, periodicallyaltering the electrostatic charge of the earth,and consequently, with sufficient power, thepressure over its entire surface. "A connectionto earth, either directly or through a condenser

is essential."[27] The placement of a groundedTesla coil receiver tuned to the same frequency

as the transmitter at another point on the surface results in the flow of electriccurrent through the earth between the two, while an equivalent electricaldisplacement occurs in the atmosphere. This current can be used at the receiverto drive an electrical load, which in the case of an individual World WirelessTelecommunications System receiver is a sensitive device using only a small

amount of energy. [28]

In 1891 and 1892, Tesla demonstrated the oscillatory transformer that bears hisname in lectures delivered before meetings of the American Institute of Electrical

Engineers (AIEE) in New York City"[29] and the Institute of Electrical Engineers

(IEE) in London,[30] and in a later presentation titled "On Light and Other High

Frequency Phenomena" (Philadelphia/St. Louis; Franklin Institute in 1893),[31]

where he put forward his ideas on the wireless transmission of electrical energy.
