NOVELTY - The system has a stabilizing column (3) whose end is secured to an underwater surface i.e. sea bed, and another end is extended away from a water surface. A rectangular platform (1) floats partially above the water surface, and is coupled with the column. Position of the platform is changed relative to the column in response to tidal variations. An electric generating system is attached to the platform and converts changes of position of the platform to electrical energy in relation to the column. Multiple rack gears (4) are attached to the column and coupled to the generating system.    USE - Integrated lunar tide electric generator and floating retail structural system for supplying electricity to constructional developments such as retail arcade space i.e. shops, and residential units such as commercial, residential or industrial buildings.    ADVANTAGE - The system can convert the vertical change in water levels due to lunar tides based on tidal variations into electrical energy without depending on a tidal barrage, so that inland water levels are not affected and local wildlife and fish migration are not disrupted. The system can provide usable space to develop constructional development such as retail, commercial or residential spaces. The electricity produced can be directed into an electric power grid utilized by local electric utilities or directed to the electrical demand created by the constructional development. The constructional development can provide additional revenue due leasing or renting the retail spaces. The system is unique and can retrofit existing floating structures for floating docks and marinas. The platform includes housing to protect the electrical generating system and series of reduction gears from weather such as hail, and wildlife such as birds. The housing can cover two stabilizing columns and associated equipment so as to reduce construction costs of the housing, thus providing a large space for retail structure development on the top side of the platform such as shops, commercial, residential or industrial buildings.
