Magneto-static flux manipulator prepared for future geomagnetic power plant

Magnetic flux resulting from geomagnetic anomaly is a natural energy source that never runs out, driven by tectonic settings or specific rock structures. Unfortunately, this natural resource has not been exploited at all; therefore frontier technological innovations in electromagnetic fields are required. Geomagnetic flux concentrator is a system designed to actively collect the Earth's magnetic fluxes and direct them in a catchment area, in order to increase the geomagnetic output flux densities to meet the required densities of common electrical generators. Earth's magnetic fields are of very low frequency or nearly static field that must be firstly manipulated to achieve a cut-off frequency, needed to be able to steer them through the waveguides. The designed magneto-static flux manipulator worked by periodically placing a round shielding sheet, which is continuously fast rotated across the constant magnetic fluxes flow. Hence the fluxes on the opposite side of the shielding sheet will turn into high frequency geomagnetic pulses (of some MHz), so that they will be just likes a series of electromagnetic waves which are spatially separated, then they will be able to be further guided and concentrated. This paper report the initial results of performance tests of the magneto-static flux manipulator, tested with a Helmholtz coil in a calibrated semi-anechoic chamber. The manipulator was tested in the Lombok Island, which is located at the highest intensity of the geomagnetic anomaly of Indonesian region. Results show that the manipulator performed good frequency manipulations up to about 60 Hz for rotated shielding of 900 rpm, which will be possible to reach the higher frequencies.
