A downhole tool string component, having a first rotor secured within a bore of the component and connected to a gear assembly, the gear assembly being connected to a second rotor. The gear assembly has a gear ratio adapted to rotate the second rotor faster than the first rotor. The second rotor is in magnetic communication with a stator which has an electrically conductive coil, the electrically conductive coil being in communication with a load.
