In accordance with one embodiment, a machine for generating electrical energy comprises a housing. A rotor has interior blades for rotation in response to receipt of material. The rotor has an outer surface and an inlet. A first magnet assembly is secured to the outer surface of the rotor. A first stator winding is in electromagnetic communication with the corresponding first magnetic assembly, such that if the rotor rotates a first electromagnetic signal energizes the first stator windings based on the flow of material into or through the inlet.
