Tesla developed many versions of the oscillator and looked on it as a possible replacement for inefficient reciprocating steam engines used to turn generators, but it was superseded by the development of highly efficient steam turbines. Tesla also used the highly regular tunable oscillation of the device to set frequency in his high frequency electrical and wireless transmission experiments.[1] There are also claims it had a physiological effect on people subjected to its vibrations in that it acted as a laxative causing people to immediately run to the bathroom afterwards.[3]
