1. A turbine generator regenerative braking system for braking a rotating shaft, said braking system comprising:

  • a rotating shaft of a piece of machinery;

    a plurality of hydraulic fluid pumps adapted to be mechanically linked to said rotating shaft so that said rotating shaft powers the pumps;

    a hydraulic fluid circuit having one end in fluid communication with said hydraulic pumps and a second end comprising an adjustable-outlet jet nozzle;

    an hydraulic fluid turbine generator positioned near said jet nozzle and having an electrical power output connected to a battery device;

    wherein said rotating shaft is slowed by mechanically linking said rotating shaft to said hydraulic fluid pumps to pump hydraulic fluid to the jet nozzle so that the jet nozzle sprays hydraulic fluid on the generator to generate electricity; and

    wherein said rotating shaft is stopped by closing said jet nozzle.
