Abstract
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.
