A variable density actualizing means is provided for supporting one or both of temporarily condensed electric charge and intensified magnetic flux flow and for thereby generating electrical energy. More specifically, such an actualizing means comprises: (a) condensing means for condensing one or more of an amount of electrical charge supplied from a charge donating source and flux flow induced by a magnetic field generated by a magnetic field source; (b) decondensing means, integrated with the condensing means and couplable to one or more energy sources, for reducing the density of (decondensing) the charge and/or flux flow condensed by the condensing means, the decondensing being powered by input energy received from one or more of the energy sources; wherein the decondensing means is powered by at least one of (b.1) heat energy received from one or more of the energy sources; (b.2) pressure energy received from one or more of the energy sources; (b.3) displacement energy received from one or more of the energy sources; (b.4) electrolytic ion removal energy received from one or more of the energy sources; (b.5) dielectric constant reducing energy received from one or more of the energy sources; and (b.6) magnetic permitivity reducing energy received from one or more of the energy sources. The variable density actualizing means of one embodiment is provided as an integral part of a compressor of compressible fluids (i.e., refrigerants). The variable density actualizing means of one embodiment is provided as an integral part of a fluid condenser and/or heat radiator.
