The electrical conductivity of these materials varies gradually with the degree of solidification, and when the materials get moderately hard the conductivity becomes practically nil. The author let solidify a mixture of these materials in a strong electric field applied through all the time in which the solidification went on.The electret shows so great an intensity of electrization that the electric force exerted in front of the surface of the electret may attain the greatest sustainable value in the atmosphere.The permanency of these charges is so good that we cannot detect any sensible decay after many years. We shall call these surface charges of the electret the free charges due to its proper electrization.

2 The term "Electrization" is used after Heaviside to signify the internal electrical change of a material, which is different from superficial electrification.

It really works neat. I modified the relay so it would oscillate a simple CFL circuit at the same time that it was charging. I ran the relay off my small 2 watt solar panel. Really cooooollll. I didn't hookup the ground or antenna to it---yet.

Sparking of the commutator inside the hobby motor can make your meter erratic. If you want to rule this possibility out buy a simple panel meter or analogue gauge and place it in parallel with your digital meter. If you still get erratic readings you could be onto something. Or if your DC motor is brushless then this is a different story. Remember a commutator is like a simple switch, in a way it is similar to the single relay circuit shown recently by Imhotep. So the make and breaks of the commutator inside the hobby motor causes the inductive spike, in this case it doesnt have anywhere to go, its not directed anywhere upon coil collapse. You will probably find that your meters continue to become more erratic the more you try to measure this type of electricity, I have about 8 cheap DVMs sitting here which all do the same thing.
