1. A method for removing harmonic noise from an electrical signal transmitted by a power transmission line, the electrical signal transmitting electricity at a primary frequency, the method comprising:

  • separating, via a filter, electricity at a harmonic of the primary frequency from the electrical signal transmitted by the power transmission line; and

    controlling, via a controller, consumption of the separated electricity at the harmonic of the primary frequency from the power transmission line, the consumption controlled by electrical actuation of a motor coupled to an elastically deformable component, the consumption controlled such that the separated electricity at the harmonic of the primary frequency is consumed through the electrical actuation of the motor,wherein the motor is coupled to the elastically deformable component, such that electrically actuating the motor causes the motor to generate tension in the elastically deformable component.
