Please note updated: decription is the 1907 Article published in English Mechanic and World of Science
What is offered here has no known parallel in more than twenty years of public auction: a holograph page from a Nikola Tesla scientific manuscript, signed in full, and containing one of the most audacious weapons concepts ever committed to paper. This is the concluding page of Tesla's working draft for "Tidal Wave to Make War Impossible," published in English Mechanic and World of Science on May 3, 1907. Tesla autograph letters are exceptionally rare; a working manuscript page in his hand from a major scientific publication is, to the best of current knowledge, unique.
The passage Tesla wrote out on this page describes, in precise engineering terms, a remotely operated vessel weaponized to harness the destructive force of ocean swells against an enemy fleet. The concept was not metaphorical: Tesla calculated that wave action could drive a submerged vessel downward from a height of seventy-five feet in something approximating free fall, generating an impact force of sixty thousand tons against the hull of a warship. That force, he wrote, was eight times the recoil of the broadside of any battleship then afloat. The vessel, once committed, would sink beneath the surface never to rise. The weapon was to be guided entirely by remote wireless control: no crew, no pilot, no human presence aboard. It was, in the clearest possible terms, the world's first conceived remotely operated weapon of mass naval destruction, designed more than a century before such systems became reality. The manuscript reads in part:
"...will be over one hundred feet. Diagram fig 7 shows the successive positions of the vessel in the swell. The first impact of the water will produce pressures of three tons per square foot, which acting over the exposed surface of, say, twenty thousand square feet may amount to sixty thousand tons, eight times the force of the recoil of the broadside. That first impact may in itself be fatal. During more than ten seconds the vessel will be entirely submerged and finally dropped into the hollow from a height of about seventy-five feet, the descent being effected more or less like a free fall. It will then sink far below the surface never to rise."
Tesla signed the page in full, "Nikola Tesla," directly below the final sentence, as though formally sealing the argument. The 1907 article was a direct response to the naval arms race then convulsing Europe, published at the moment Britain had just launched HMS Dreadnought and nations were pouring treasure into ever-larger battleships. Tesla's argument was characteristically sweeping: that his telautomaton technology rendered the capital ship obsolete and that remote-controlled tidal wave generators would make war itself impossible. The weapons passages were the sections most alarming to military readers and most prophetic to posterity. This manuscript page is where those ideas reached their written endpoint. The accompanying original period photograph, a large-format silver gelatin print depicting an elderly Tesla standing in a corridor, hat and cane in hand, bears a pencilled annotation "16x20 left," while the manuscript page itself is annotated "16x20 right" in the same hand, confirming the two were archived and catalogued together as a matched pair by a prior keeper of the material.
