Patent ID: 7986054

Claim:
An energy harvester, comprising: a fluid flow path defined by an inflow fluid channel, an outflow fluid channel, and a chamber disposed between said inflow fluid channel and said outflow channel; a Magnus rotor transversely mounted in said chamber and being movable in said fluid flow path between a first position and a second position, said Magnus rotor being rotationally driven by a motor; at least one counter balancing system cooperatively associated with said Magnus rotor; a means for producing an electrical current from a movement of said Magnus rotor in said fluid flow path, said means for producing said electrical current comprising, a rack movable in response to movement of said Magnus rotor, and at least one pinion gear drivable by a movement of said rack, said pinion gear being operably connected to an electrical generator, wherein driving of said pinion gear operably connected to said electrical generator produces said electrical current; a battery for charging by said electrical current produced from said means for producing said electrical current; and means for connecting said battery to an electrical grid.
