A system for generating DC electric voltage, comprising: a means for concentrating similarly polarized magnetic flux lines (101, 112, 122) around a circumferential portion of a magnetic cylinder to create an area of magnetic concentration comprising a stacked plurality of similarly polarized magnetic flux lines (101, 112, 122), at least one coil segment a means for coupling the coil segment to a longitudinal shaft such that as the longitudinal shaft rotates around an axis, the coil segment is moved into the area of concentration, a means for producing a voltage in the coil segment as the plurality of flux lines (101, 112, 122) within the area of magnetic concentration are compressed, and a means for removing the voltage from the coil segment, characterized in that: the circumferential portion of the magnetic cylinder is positioned about the axis and includes a radially external curved wall, a radially internal curved wall, and two annular shaped axial side magnetic walls (170, 172) defining an interior cavity in section, having an open end defined on one circumferential side of the interior cavity, and an opposing open end defined on the opposing circumferential side of the interior cavity such that the circumferential portion of the magnetic cylinder forms an open segment without magnets; wherein magnetic poles of magnets (106, 108) forming the magnetic walls (102, 104) and side magnetic walls (170, 172) which face into the magnetic cylinder are of the same polarity and are configured to manipulate magnetic flux lines (101, 112, 122) to flow circumferentially from the magnets (106, 108) through the interior cavity and out one of the open ends (114, 116) of the interior cavity where the circumferential portion of the magnetic cylinder forms the open segment. a means for concentrating similarly polarized magnetic flux lines (101, 112, 122) around a circumferential portion of a magnetic cylinder to create an area of magnetic concentration comprising a stacked plurality of similarly polarized magnetic flux lines (101, 112, 122), at least one coil segment a means for coupling the coil segment to a longitudinal shaft such that as the longitudinal shaft rotates around an axis, the coil segment is moved into the area of concentration, a means for producing a voltage in the coil segment as the plurality of flux lines (101, 112, 122) within the area of magnetic concentration are compressed, and a means for removing the voltage from the coil segment, the circumferential portion of the magnetic cylinder is positioned about the axis and includes a radially external curved wall, a radially internal curved wall, and two annular shaped axial side magnetic walls (170, 172) defining an interior cavity in section, having an open end defined on one circumferential side of the interior cavity, and an opposing open end defined on the opposing circumferential side of the interior cavity such that the circumferential portion of the magnetic cylinder forms an open segment without magnets; wherein magnetic poles of magnets (106, 108) forming the magnetic walls (102, 104) and side magnetic walls (170, 172) which face into the magnetic cylinder are of the same polarity and are configured to manipulate magnetic flux lines (101, 112, 122) to flow circumferentially from the magnets (106, 108) through the interior cavity and out one of the open ends (114, 116) of the interior cavity where the circumferential portion of the magnetic cylinder forms the open segment.
