Website seems a little rough, but may have useful information concerning the possibility of retrofitting the power grid with over-unity slipped-pole synchronous generators that have been meta-stabilized by sharing a common torque shaft with a normally operating synchronous motor such that (Pout>Pin).

Retrofitting the Power Grid for over-unity Generation

Synchronous motor/generators, which power electrical grids world wide, are typically run in two of four possible quadrants of operation.

For motor operation, this is called the fourth quadrant, by convention, and for generator operation, the first quadrant. The operating characteristics of these machines in the other two quadrants are rarely discussed in engineering classes, in part because of the inherent instability of these modes. By instability we mean that if a machine slips a pole and enters into one of these quadrants by mistake, they tend to become desynchronized with the grid voltage, draw large transient currents, trip breakers, and experience large torque pulsations – sometimes even “bouncing” off the next available pole. However, by solidly connecting the shaft of an unstable synchronous generator with the shaft of a stable synchronous motor operating in quadrant-four, we can meta-stabilize the synchronous generator, with interesting results with regards to over-unity power generation...
