An energy harvesting device (EHD) comprising: a. a hollow outer envelope (201) having an inner wall (200) with a first predetermined magnetic field distributed on an inner surface of said inner wall;b. at least one inner core (202), free to move in said hollow envelope (200) characterized by a se
1. An energy harvesting device (EHD) comprising: a. a hollow outer envelope (201) having an inner wall (200) with a first predetermined magnetic field distributed on an inner surface of said inner wall;b. at least one inner core (202), free to move in said hollow envelope (200) characterized by a second predetermined magnetic field distributed on an inner surface of said at least one inner core, said inner core being characterized by one or more convex projections of magnetically active material;c. at least one conducting loop (203) disposed on said at least one inner core, so as to be suffused with magnetic flux due to said first and second magnetic field distributions of said at least one inner core and said at least one outer envelope and generating an alternating current due to movement of said inner core within said outer envelope; andd. a rectifying circuit in electrical connection with said at least one conducting loop (203) rectifying said alternating current into a current having a DC component,wherein the shape of outer envelope is selected from the group consisting of molybi augmented polyhedral, cupolaic expanded rhombohedra, rhombically expanded deltahedra, skew polygon expanded polyhedral, icosidodecahedrons, Catalan solids, uniform polyhedral, isohedral polyhedral, convex polyhedral, isohedral deltahedra, acrohedra, Johnson solids, chiral prismatic polyhedral, platonic solids, and lens and lens-like patterns selected from a group consisting of convex lens, converging lens, concave lens, irregular shapes. 2. The EHD of claim 1 wherein said magnetically active materials are selected from the group consisting of: permanent magnetic material, magnetically permeable material and any combination thereof. 3. The EHD of claim 2, wherein said permanent magnetic material is selected from the group consisting of: neodymium iron boron, samarium cobalt, ceramic and alnico. 4. The EHD according to claim 3, wherein said permanent magnetic material is disk shaped. 5. The EHD according to claim 3, wherein said permanent magnetic material is in a powder form. 6. The EHD according to claim 3, wherein a direction of said permanent magnetic material is radial for said inner core and said outer envelope and of opposite magnetic polarity. 7. The EHD of claim 1 wherein said rectifying circuit is selected from the group consisting of full wave rectifier and half wave rectifier. 8. The EHD according to claim 3, wherein said inner surface of said outer unit, and said outer surface of said inner unit are at least partially covered by said permanent magnetic material. 9. The EHD according to claim 3, wherein said inner surface of said outer unit, and said outer surface of said inner unit are at least partially covered by said magnetically permeable magnetic material. 10. The EHD according to claim 1, wherein said inner unit is a piston. 11. The EHD according to claim 1, wherein said inner unit has a center of mass located distantly from a geometric center of said inner unit thereby increasing erratic movement of said inner unit. 12. The EHD according to claim 3, wherein said magnetically active materials are magnetic permeable material is disk shaped. 13. The EHD according to claim 3, wherein said magnetically active materials are magnetic permeable material is in a powder form.
