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 simple system is provided to dramatically reduce the number of bird fatalities and injuries, as these are bird-kills that man should be able to do something about. Essentially, the inventive apparatus comprises one or more instantaneously inflatable mini-airbags on turbine blade leading edges which, in the “stowed position” are tightly conformally elastically wrapped around or juxtaposed to the turbine blade surface(s) and/or edges(s) thereby not affecting the blade's aerodynamic efficiency. The airbag(s) can be activated and restowed or recollapsed very rapidly, thereby not significantly negatively impacting the operational efficiency of the wind machine. In a similar manner, fish-kills or injuries taking place in the turbine impellers of hydroelectric power-generator facilities may be avoided (as opposed to ameliorated) using another inventive system and method taught herein, this one being primarily a collision avoidance system which does not require the problematic alteration of the turbine blades themselves.

The power source also provides power to other components in the housing of the monitoring units such as temperature control, keycard access, and excess power made available at an outlet at the housing. Each monitoring unit wirelessly transmits video signals from each of the cameras to a hub or receiver that directs the images to the internet. An internet user with the proper access code can access the video surveillance and remotely control the cameras and other components of the monitoring units.
