Cut edges can be sanded so they have a white, frosted appearance that, in contrast with clear surfaces, gives your jefimmenko motor a sparkling, jewel-like appearance. The field changes constantly.

Inhe was awarded the Sigma Xi Prize. Corona rotors can of course also be made in the form of disks. Although it varies widely, strength of the field averages volts per meter. It was invented in by Benjamin Franklin. Six radially directed needle points grazed the rim of the disk at equal intervals. Such antennas produce about a microampere of current. Motors of this type are based on the force of mutual attraction between unlike electric charges and the mutual repulsion of like charges.

Although Franklin left no drawing of his motor, his description of it in a letter to Peter Collinson, a Fellow of the Royal Society, enabled Jefimenko to reconstruct a working model [see illustration at right]. But whether or not we tap this energy source, the electrostatic motor could become important on its own.

We lined up the electrodes — precisely. The electret is mounted on a four-millimeter shaft of plastic that turns in jeweled bearings. What can I say? A moment later, we lost count.


The upper end of the tinsel was hoisted aloft by a cluster of three weather balloons. Franklin charged his jars with an electrostatic generator.

Email required Address never made public. The laser beam would ionize the air, creating an invisible conductor through apparently empty space.

To run the motor connect the antenna to one set of electrodes and ground the other set. Walker, he experimented with electret motors. Acrylic cuts and works beautifully. The force of repulsion between the like charges imparted momentum to the wheel.

The tinsel functioned as multiple needle points. But its concentration is too low to be harmful. Run motors with atmospheric electricity. In this design the rotor consisted principally of a inch disk of glass mounted to rotate in the horizontal plane on low-friction bearings.

There are millions — perhaps billions — of kilowatts of electrical energy flowing into the earth constantly. To form the points I chucked the shaft in an electric hand drill, ground the metal against an oilstone and polished the resulting pivots against a wood lap coated with tripoli.

At an altitude of meters the antenna should pick up some 20, volts. The imbalance was only a fraction of an ounce — mltors it was too much.

Even they can be contrived of metallic foil backed by any stiff dielectric. Forces that act between the sprayed charges and the knife-edge electrodes impart momentum to the cylinder. The dynamic balancing, which is achieved largely by cut-and-try methods, took about as much time as the remainder of the construction.

The adjacent plates are separated by a narrow slot. The rotor consisted of a pair of electrets in the shape of sectors supported at opposite ends of a shaft.


When the rotor turned, eldctrostatic electrets were swept between adjacent pairs of charged metallic plates, which were also in the form of sectors. At the University of West Virgina we saw a laboratory full of such exotic devices spinning, humming, and buzzing away like a swarm of bees.

When the machine was started by hand, it ran equally well in either direction. Jefimenko puts on an impressive demonstration.

Jefimenko’s Electrostatic Motors & Heaviside’s Gravitational EM Analogy

Discovered by Ben Franklin in the 18th century, electrostatic motors are an all-American invention. Jefimenko suggests that electromagnetic equations can be converted to their gravitational-cogravitational equivalent by replacing electromagnetic symbols and constants with their corresponding gravitational-cogravitational symbols and constants, [1] given in the table below. 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.

The motor can be made self-starting and unidirectional by slanting the mootrs. This limitation is circumvented by a novel electrostatic motor invented in by a Russian physicist, A. A long-lasting charge is imparted to the Mylar by immersing it in a field of a few thousand volts from an electrostatic generator after the motor is assembled.

Corona motors require no brushes or commutators.

The rotor began to spin.
