Phillip Akinson, in his work on electricity, 1902, asserts that "energy manifests itself either in masses of matter or in small particles, called molecules, and thus we have two kinds--mass energy and molecular energy." But have we two kinds of energy? Mass energy and molecular energy is the same. Mass energy is but the aggregation of molecular energy. Large bodies attract small ones because they possess more electric energy. Gravity or weight is but another name for aggregate molecular electric attraction of the earth for everything upon its surface. The gravity or weight of a man is the pull or force with which the electric attraction of the earth holds him to its surface. In other words, the earth is a vast magnet, and man's body is a smaller magnet, and as the magnetic core of a steel magnet draws all metals towards its magnetic center, so does the earth magnet draw all things toward its center. The same author states that, "the earth is a great thermopile generating electric currents by the difference of potential between its heated and cooled parts." In this I agree with him, but he only states one of a thousand ways to generate electric currents. He says further: "Heat is believed to be a certain mode of molecular motion, and electricity to be another mode; but the nature of the motion of each has never been discovered." And I think never will, as long as the false notion prevails that heat and electricity are modes of motion. A mode of motion is nonsense, for motion is an effect produced by a cause--it is not a cause. And all cause of motion is electricity, and the mode of operation is the law of electro-magnetism. There is no difference in the law or the mode of operation of electric currents in a volcano, in a cloud, in the earth, in the sun or planets, in an electric light, or in a man's body. The same law exists and the same natural results follow when one lights the gas with a flash of electricity from his finger, as when a meteor blazes, a comet flares out in space, or a sun becomes luminous. The same force that man causes to run along a telegraph wire, or through a telephone circuit, or which runs a street car line, or is taken by the brushes from a revolving dynamo, is the same force and operated under the same law or mode of force as the electric life-giving currents that come from the sun constantly in an omnipotent tide of power. Prof. Thomson says: "The earth is generally found to be negatively electrified, and is insulated in its atmosphere, being in fact a conductor touched only by air--a strong insulator." He says further: "The quality of non-resistance to electric force of the interplanetary ether being considered, the earth, the atmosphere and the surrounding medium may be regarded as constituting respectively, the inner coating, the dielectric and the outer coating of a large Leyden jar charged negatively."
