Abstract: Techniques in which a 1st force, field, or effect caused by a Casimir effect is converted into a 2nd force, field, or effect. The 1st force, field, or effect might be distinct from the 2nd force, field, or effect only in the net vector or might be distinct in other ways. For example, the distinction might involve substituting a torque for a linear force vector or converting a force, field, or effect associated with the Casimir effect into movement or into an electric, magnetic, or electromagnetic force, field, or effect. These changes preferably are caused by an independent element placed proximate or between to the Casimir effect surfaces. Preferably, the torque causes rotation (i.e., spinning) of an element. This rotation is significantly different from prior-art embodiment because energy does not have to be put back into the system to “reset” the structures.

Abstract: A system is disclosed for converting energy from the electromagnetic quantum vacuum available at any point in the universe to usable energy in the form of heat, electricity, mechanical energy or other forms of power. By suppressing electromagnetic quantum vacuum energy at appropriate frequencies a change may be effected in the electron energy levels which will result in the emission or release of energy. Mode suppression of electromagnetic quantum vacuum radiation is known to take place in Casimir cavities. A Casimir cavity refers to any region in which electromagnetic modes are suppressed or restricted. When atoms enter into suitable micro Casimir cavities a decrease in the orbital energies of electrons in atoms will thus occur. Such energy will be captured in the claimed devices. Upon emergence form such micro Casimir cavities the atoms will be re-energized by the ambient electromagnetic quantum vacuum.
