A new plan for marine green energy system; Gravity Buoyancy system in deep waters

This essay is about an innovative plan for generating electric energy by gravity- buoyancy (GB) method. This plan is based on the positive and negative buoyancy principle. This principle is discussed here. This plan is a backup and reserve system beside other new energy generation systems such as wind, tide, solar and seawave system. This system can be combined as an efficient unit for energy generation. GB method can generate electric energy by using the depth of water in sea, lake or water well. For assessment and approval the application of this system, a small prototype has been built in laboratory and its specification has been presented here. In this paper provided results from energy produced by laboratory sample with the presented specific and effective parameters in system efficiency was surveyed by numerical analysis methods. This system has a buoyant volume, ballast tank and two vertical rods for vertical ascent and descent. There are some installation for diving and surfacing such as high pressure air system and solenoid valves.The buoyant volume has negative buoyancy when dives and has positive buoyancy when surfaces. Vertical movementof this volume causes rotation of two circular devices that result in rotation the axis of an electric generator. This generator produces electric energy. Concept of this method is dive by downward gravity force and ascent by upward buoyancy force. On the other hand, if the system has negative buoyancy (weight more than buoyancy) will dive to the depth and if the system has positive buoyancy (weight less than buoyancy) it will ascent to the surface of water. This method is very efficient in compared to other systems because it is independent from the geographical location, season and weather. The more depth of water causes greater efficiency in this method. This essay provides a background of theoretical basis and application of a new marine green energy generation system.
