Wind turbine and wave/tidal energy generator 100 may incorporate, in its upper part, a vertical axis wind turbine energy generator 101 and in the lower part, a wave/tidal energy generator 102. The cylindrical frame 100A of the wind turbine and wave/tidal energy generator 100 may incorporate an upper cylindrical frame 106 and a lower cylindrical frame 108.

[0033] The vertical axis wind turbine energy generator 101, in the upper part, may incorporate a vertical axis blade assembly 103, which may be connected to the rotor shaft 104 traveling through to the magnetic rotor chamber 116. An upper cylindrical frame 106 (also shown in FIG. 4 as 406), can include a magnetic rotor chamber 116 and a frictionless levitation chamber 114.

[0034] The magnetic rotor chamber 116 may have a first through hole 129 disposed at top cap 125, and a second through hole 117 disposed at partition wall 132. The first bearing 126 may be provided in the first through hole 129 and the second bearing 126A may be provided in the second through hole 117. The rotor shaft 104 may be pivotally placed within the magnetic rotor chamber 116 through the first bearing 126 in the top cap 125 and through the second bearing 126A in partition wall 132. Magnet assemblies 121 and 121A are fixed to the rotor shaft 104 and in between them is located the static induction coil assembly 127 (more detailed explanation in FIG. 4, below). Rotor shaft 104 may freely rotate, responsive to the wind force exerting unto the vertical axis blade assembly 103, which rotates the magnet assemblies 121 and 121A around the static induction coil assembly 127 in order to generate electricity. Static induction coil assembly 127 may be secured to the upper cylindrical frame 106 (more detailed explanation in FIGS. 2B and 4, below). The wind turbine and wave/tidal energy generator 100 is positioned in a body of water such that the upper cylindrical frame 106 and the vertical axis wind turbine energy generator 101 may be elevated above the water line.

[0035] The wave/tidal energy generator 102, at the base, may incorporate a cylindrical ballast foot 105 connected to bottom of the lower cylindrical frame 108 which internally may incorporate magnetic array chamber 112 and externally may incorporate floating induction coil assembly 122. The floating induction coil assembly 122 may rise and fall, responsive to the wave/tidal motion, thereby generating electricity due to induction as the floating induction coil assembly 122 interacts with the magnetic array chamber 112 (explained in detail below). The magnetic array chamber 112 may incorporate a magnetic array axle 113. A plurality of magnets may be attached to the magnetic array axle 113 in some order along the length of the magnetic array axle 113. The magnetic array axle 113 may be secured in the upper portion to the partition wall 131 and in the lower portion to the cylindrical ballast foot 105. The wave/tidal energy generator 102 may be submerged into the body of water in such a way that the floating induction coil assembly 122 could rise and fall in response to the waves/tides, at least along the length of the lower cylindrical frame 108.

[0036] Frictionless levitation chamber 114 is located between the partition wall 132 and the partition wall 131. Partition wall 131 may have a through hole 119.

[0037] The static permanent magnet 120 may have repulsive surface 120A which may be counterposing the repulsive surface 118A of the revolving permanent magnet 118 such that a distance between them is created and maintained due to the force of having like magnetic poles facing one another. This repelling force causes the rotor shaft 104 to levitate. The levitation force may be formed between the static permanent magnet 120 and the revolving permanent magnet 118. The levitation force reduces resistance while the rotor shaft 104 is driven by the vertical axis blade assembly 103 because the friction otherwise created is minimized if not eliminated. Inevitably, this increases revolving efficiency and speed.
