Abstract: There is provided a flywheel apparatus comprising a plurality of flywheels configured to be mounted on a rotating shaft having a longitudinal axis, each one of the flywheels having a mass concentration in a predefined zone within its surface such that the net torque required for maintaining the rotation of the flywheels when combined with a constant angular velocity about the longitudinal axis of the rotating shaft is null. There is also provided use of a flywheel apparatus with an electrical energy generation system.

Abstract: There is provided a closed-loop electrical energy regenerative system comprising (i) a regenerative electric motor for receiving a load of electrical energy for the purpose of conversion into kinetic energy; (ii) an alternator for generating an output load of electrical energy; (iii) a rotating shaft and at least one flywheel, the rotating shaft being configured to be connected to the regenerative electric motor, to the alternator and to the at least one flywheel for transferring a first portion of the kinetic energy from the regenerative electric motor to the alternator for the purpose of generating the output load of electrical energy and for transferring a second portion of the kinetic energy to the at least one flywheel for storage for the purpose of assisting in rotating the rotating shaft through subsequent cycles; (iv) a first electrical output for directing a first portion of the output load of electrical energy outside the system for consumption by an electric power system; and a second electrical ou
