The current was flowing from the generator through the air to where it was being picked up by the antenna. Then the attraction-repulsion routine that Franklin used takes place. To form the points I chucked the shaft in an electric hand drill, ground the metal against an oilstone and polished the resulting pivots mogors a wood lap coated with tripoli. The charm of these motors lies in the fact that, although they do not accomplish very much, they can run forever.

When adjacent plates carry charges of opposite polarity, the electret experiences a force at right angles to the slot and in the plane of the electret. The brushes are one-millimeter strips of kitchen aluminum foil.

Electret Scientific, Star City, Jefimenko estimates that corona motors could deliver one horsepower for each 3 pounds of weight.

It employed stiffbacked single-edge razor blades as electrodes. Motors based on the slot effect electrosstatic be designed in a number of forms. In one form the modern corona motor consists of a plastic cylinder that turns on an axial shaft inside a concentric set of knife-edge electrodes that spray charge on the surface of the cylinder [see illustration at left].

He has learned that their performance can be vastly improved by ,otors shaping the corona-producing electrodes [see illustration at right].

Both surfaces of the disk were coated with a film of gold, except for a boundary around the edge. On the night of Sept.

The rotor consisted of a pair of electrets in the shape of sectors supported at opposite ends of a shaft. Jefimenko puts on an impressive demonstration.


Franklin was incredibly lucky to have survived his celebrated kite experiment. The commutator applied to the electrodes a charge of polarity opposite to the charge of the attracted electret.

According to Franklin, this machine would make up to 50 turns a minute and would run for jefimenlo minutes on a single charge. That deposited a like charge on the thimble, so they repelled each other.

It is the kind of wire normally employed for interconnecting electronic components and is available from dealers in radio supplies. But whether or not we tap this energy source, the electrostatic motor could become important on its own. The motor is based elrctrostatic an electret made in by Mototaro Eguchi, professor of physics at the Higher Naval College in Tokyo. When Franklin placed opposite charges on the top and bottom films and gave the rotor a push, the machine ran just as well as his first design, and for the same reason.

It produces a permanent electrostatic charge in the surrounding space, just as a magnet produces a permanent magnetic motros. Books by Professor Oleg Jefimenko also available from http: Electrostatic motors are lighter than electromagnetic motors for the same output power since the motor occupies the entire volume. A potential of at least 2, volts, however, is essential for initiating corona discharge at the knife-edges.

Static balance was achieved by experimentally adding small bits of adhesive tape to the inner surface of the aluminum foil that lines the cylinder until the rotor remained stationary at all positions to which it was set by hand. This rotor is sandwiched between four semicircular sectors that are cross-connected [ see illustration ].

If nothing happens, check your equipment, or try another day. He showed us motors that run on the voltage developed when you hold them in your hands and scuff across a carpet, and other heavier, more powerful ones that could do real work. He received his Ph. Brown, these antennas have larger current potentials depending upon the radioactive source used alpha or beta source and ionize the air in the vicinity of the antenna. What can I say? Yet there leectrostatic is, spinning merrily.

The charged particles cause the electrical field that Jefimenko saw demonstrated. Alternatively the rotor could be made cylindrical to carry electrodes in the form of long strips or plates. At an altitude of meters the antenna should pick up some 20, volts. Jefimenko posits the following Generalized Theory of Gravitation. When we crank up the electrostatic motor at the top of this page, people always want to know what makes it run. We drilled out the old hub and cemented in a new one — this time, carefully.


The Poggendorff motor looked simple; we slapped it together in a couple of hours, hooked up the power elcetrostatic — and nothing happened.

I found this story behind some esoteric equations to be pretty amusing, and thought others might agree.

The energy of the field can be tapped with a mootors antenna in the form of a vertical wire that carries one sharp point or more at its upper end. Why not tap the field to supplement conventional energy kefimenko Twelve evenly spaced metal spheres, cemented to the edge of the disk, were connected alternately to the top and bottom gold films.

You can measure this voltage with an earth-field antenna — a wire with a sharp point at the top to start a corona, or with a jefimenio of radioactive materials that ionizes the air in its immediate vicinity.

At higher altitudes the rate decreases. Electrostatic motors are now classified in general by the method by which charge is either stored in the machine or transferred to the rotor.

Adhesive tape makes a convenient counterweight material because it can be both applied and shifted easily. In his opinion, there is no objective reason for abandoning Newton’s force-field gravitational theory in favor of a metric gravitational theory. The stunt had a serious purpose: Then we noticed that the disk always stopped with one side down. These remarkable machines are almost unknown today.
