Abstract
When powdered materials are blown through metal tubes by means of compressed air considerable quantities of electricity are produced by contact electrification. It was found that 6\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}5}$ coulombs could be produced per gram of diatomaceous earth, a form of silica, blown through a short length of copper tube. A generator of extremely high voltage is proposed, and a small scale model of such a generator is described, by means of which currents of 8\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}5}$ amperes at 260 kilovolts were generated.
