A miniature hydro-power generation system includes an outer housing and an inner housing. The outer housing may receive a flow of liquid flowing in a first direction at a predetermined range of pressure. The flow of liquid may be decreased by a predetermined amount of pressure and increased by a predetermined amount of velocity and channeled to a hydro-generator included in the inner housing with an inlet nozzle. The flow of liquid may be channeled with the inlet nozzle to flow in a second direction that is substantially perpendicular to the first direction. Upon transfer of kinetic energy in the flow of liquid to the hydro-generator, the inner housing may rotate in the second direction. The flow of liquid may then be channeled back to the first direction and out of the housing with an outlet nozzle. The outlet nozzle configured to increase the pressure and decrease the velocity of the flow of liquid to minimized non-laminar flow characteristics.

A power plant extracts energy from a free flowing motive fluid by means of a transverse mounted generator with its rotor extending downward into the flow. Runner blades with hinges attain the greatest surface area when the flow is tangent to and in the same direction as the rotor rotation. The hinges fold the runner blades to minimize the surface area proportional to drag when the blades oppose the flow. The generator with feedback control charges batteries, produces hydrogen fuel by electrolysis of water, or further couples to a DC motor coupled to an AC generator. Other features optionally perform such tasks as adaptively locating the generator in the maximum velocity flow, controlling and communicating the state of charge of the battery, or gauging and controlling the electrolysis process and communicating the fullness of the hydrogen gas output tanks.
