"Stripping the process of all technical terms, it is simply this: I take water and air, two mediums of different specific gravity and produce from them by generation an effect under vibrations that liberates from the air and water an interatomic ether. The energy of this ether is boundless and can hardly be comprehended. The specific gravity of the ether is about four times lighter than that of hydrogen gas, the lightest gas so far discovered. I can best answer you intelligently by explaining the operations of the gun I used at Sandy Hook Proving Ground. It was a breech loading rifle weighing 500 pounds. It was specially constructed for me. On Wednesday last I charged my tube, a five-gallon reservoir of wrought iron, one and a half inches thick - with etheric vapor. Then I boxed it up and did not ever test it, so I was certain of its powers. There, hours before the experiments, it remained untouched in my shop. The process of charging it consumed less than four seconds of time. [Keelys Etheric Vapor]
