By Oleg Jefimenko, Thomas Valone, David K. Walker
The main authoritative and accomplished publication as regards to utilizing excessive voltage electrical cost to energy a motor. The booklet indicates the kind of electrostatic motor that was once first invented by way of Ben Franklin in 1748. It additionally stories and illustrates electrical pendulum automobiles, electrical wind automobiles, Franklin's spark vehicles, capacitor vehicles, inductance automobiles, corona cars, liquid immersed automobiles, electret cars and extra. The final bankruptcy exhibits how the electrostatic motor should be designed to be powered by means of atmospheric electrical energy, which Professor Jefimenko experimented with on the collage of West Virginia. the writer is especially meticulous to provide dates and references for the historic use of fairly particular electrostatic vehicles. Dr. Jefimenko's articles from Popular Science journal are reprinted within the Appendix in the event you are looking to construct their very own electrostatic motor. He additionally stories the atmospheric strength for producing strength, stating it truly is within the gigawatt variety. The ebook additionally contains his evaluate article at the earth's electrical box as a traditional resource of electrostatic power.

41 FIGURE 21 Franklin's second "electrical wheel" was more efficient than the Jirst. It was powered by the electric charge stored in its capacitar-rotor. 42 iron fixed in its lower end and was kept in the vertical position by a strong wire mounted in its upper end and passing through a small hole in a thin stationary brass plate. Two oppositely charged Leyden jars (bottles) were placed in close proximity to the thimbles on the spokes, so that when the wheel turned, the thimbles barely missed the knobs of the jars.
