Summary
Quantum mechanics provides an easy way to implement a version of Maxwell’s pressure demon that produces electricity directly. This violation of the second law of thermodynamics means that there are possibly ways to extract useful quantities of energy directly from the thermal energy of a gas at room temperature. This may at some future date lead to devices that can operate on the temperature of the environment directly. Such devices should no longer be dismissed out of hand as impossible simply because they violate the second law of thermodynamics.

As I have stated repeatedly, we have several magnetic devices that are Over Unity. We simply do not reveal proprietary information to the public.

Superconductivty, prior to the IBM breakthrough in 1985 that earned a Nobel, was explained, in the opinion of almost all scientists, by BCS theory, which earned a Nobel some years earlier. When SC was discovered in ceramics, that forced a reexamination of the BCS theory, which did not explain the phenomena. There were numerous theories floating around for a few decades. It now appears the number has been reduced to less than ten. Our Ultraconductors are not explained by any of them. The Quantum Mechanical theory we have published in Philosophical Research B, the oldest scientific journal published in the U.S., fits the many lab experiments, but it too may be replaced by better understanding in the future.
