ECE generalization of the d’Alembert, Proca and superconductivity wave equations: electric power from ECE space-time. §7.2; http://aias.us/documents/uft/a51stpaper.pdf

The well known d’Alembert, Proca and superconductivity wave equations are shown to be special cases of the wave equations which can be constructed from the homogeneous and inhomogeneous field equations of Einstein Cartan Evans (ECE) unified field theory. One of the important practical consequences is that a material can become a superconductor by absorption of the inhomogeneous and homogeneous currents of ECE spacetime. This means that in a well de-signed circuit or material, the output voltage or power can exceed by orders of magnitude the input power needed to run the circuit. This phenomenon has been observed experimentally and is reproducible and repeatable. An array of such circuits would in principle produce a new type of electric power for general use on a sufficiently large scale to be significant
