Text: So far as can be ascertained from his writings, Keely never produced the electric flow by his vibrations. However, he has the following to say regarding its possibility, reasoning from the laws that had already been revealed to him. "When electrical experts can construct a mechanical device whereby the low frequencies of the enharmonic can be assimilated to the harmonic undulatory by thirds, their dynamos will run without extraneous power. A concordant introductory impulse to the enharmonic (giving it the relation of true thirds to the dominant) would more effectually operate the dynamo than any number of steam engines, allowing the harmonic stream to be the governor. This concordance with the dominant would alter the ruling conditions of the harmonic and enharmonic by only exciting the sympathetic action of the dominant without arousing its destructive effects. Many lives will probably be lost before this mechanical adjustment is obtained. Tesla has left all electrical explorers far behind and has reached ALMOST to the crest of the harmonic wave. However, I do not believe the present methods of handling electricity will not be changed for hundreds of years. My failures of the past decade will be redeemed by one position, that is, my control of the polar forces through the polar sympathetic harness I have invented." [Snell Manuscript]
