It should be borne in mind that electrical energy obtained by harnessing a waterfall is probably fifty times more effective than fuel energy. Since this is the most perfect way of rendering the sun's energy available, the direction of the future material development of man is clearly indicated.

I have obtained... spark discharges extending through more than one hundred feet and carrying currents of one thousand amperes, electromotive forces approximat…

Electric current, after passing into the earth travels to the diametrically opposite region of the same and rebounding from there, returns to its point of depa…

That electrical energy can be economically transmitted without wires to any terrestrial distance, I have unmistakably established in numerous observations, exp…
