## Relativity And The Faraday Disk

Though space limitations prohibit a full theoretical analysis, most treatments of the HPG and the OPFG reviewed start with the Lorentz force to calculate the E field (E = v X B) and measurable voltage (emf). However, Becker notes in regards to the HPG, "we need the concept of the Lorentz force which is foreign to the Maxwell theory but is derivable by relativity theory" [23]. Then the nonvanishing divergence of the HPG effective electric field (E=Bwr, where w is the angular velocity) leads to a volume charge density for the generator, which correlates with the electrostatic field derived earlier. Library research revealed that special relativity can be used to describe the HPG and the OPFG, through use of the polarization/magnetization vectors of electromag-netism which are oppositely paired [24]. However, since the rotating disk is truly a non-inertial reference frame, general relativity must strict-

ing disk. He tried to measure these emfs in rivers and streams [16). Other scientists have committed a similar mistake, notably Corson [17], not knowing that such emfs are equally cancelled within the rotating frame by a self-created electrostatic field oppositely directed by the charge displacement [18]. Because B is not changing in time, curl E = 0. Therefore, the electric field that is created must be irrotational, i.e. electrostatic. (A lab test of the electrically neutral environment in the rotating frame is summarized in the Laboratory section.)

Though the emf of the earth's SSOPFG is not measureable on the surface of the rotating earth, some scientists believe the emf effect is most noticeable in the aurora borealis [20], In fact a few have calculated the voltage that should be measurable from the pole to the equator in the magnetosphere [21]. Furthermore, some have even attributed the same HPG effects to the electromagnetic fields of stars [22].

## Renewable Energy

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
