A hydro-generation system includes housing having a passageway, a turbine nozzle, a rotor and a stator. The rotor includes a plurality of turbine blades and a permanent magnet. A flow of liquid may enter the passageway and be directed by the turbine nozzle to the turbine blades to induce rotation. The stator is position within the permanent magnet such that rotation of the permanent magnet induces the production of the electrical energy in the stator. The flow of liquid may flow through the housing and out of the hydro-generation system.
