Rowland’s student in Baltimore,
Edwin H. Hall, based on his teacher’s work, had done an experiment in which he had placed a gold leaf strip in which a current was
flowing into a magnetic gap, producing an electromotive force at right angles to the magnetic field and the current, proportional to the product of the two.
2This is called the Hall Effect, and we know that
it was influential on Tesla, because he mentioned it many times, because it is the basis for MHD (Magneto-
Hydro-Dynamic) generators and pumping, and was used by Tesla in his electro-propulsion.
In his 1891 lecture, Tesla stated that the enormous electrostatic forces
emanating from the earth, “rigidifies” the ether within earth’s electric field, as it moves through space like a charged metal ball (due, as he would later say, to earth’s movement through space at over 70,000 mph.
To Tesla, the ether was composed of independent carriers, immersed in an insulating fluid while this ether behaves as a solid to heat and light, it behaves
like a fluid to solid bodies, which are allowed to pass through it.
3Furthermore, according to Tesla’s analysis, a DC. brush current could be used on the forward end of a ship,
to create a rarefaction of, and rapid exchange of the carriers, which would stretch the medium and create an inducement of movement in that direction, while a high frequency alternating current
would be used on the opposite, trailing end, to cause a compression of the carriers, which would block their passage.
