REVERSIBLE WIND TURBINE FOR COASTAL ENERGY HARVESTING

Abstract

A reversible wind turbine designed for coastal energy harvesting can efficiently capture both onshore and offshore winds, maximizing energy production. Conventional wind turbines are limited to unidirectional wind, which reduces efficiency in coastal areas with frequently changing wind patterns. This innovative turbine design features a bi-directional rotor system, enabling it to harness wind from both directions without mechanical adjustments, thus reducing wear and maintenance costs. Equipped with an aerodynamic blade structure optimized for turbulent coastal winds, it delivers consistent performance in fluctuating conditions. The turbine's versatility in harnessing variable wind flows makes it particularly suitable for coastal and island regions, where winds change due to land-sea temperature differences. Implementing reversible wind turbines could significantly increase energy yield, making renewable energy more viable and accessible for coastal communities, contributing to sustainable energy goals, and reducing reliance on fossil fuels in regions with dynamic wind patterns.

THE FIELD OF INVENTION (Mechanical)
The present invention relates to novel design reversible wind turbine for coastal energy harvesting
is mainly usedfor general purposes.
BACKGROUND OF THE INVENTION
A rotor blade is used in combination with a submersible electrical generator for generating
electricity to be put into the grid, where the pitch of the rotor blade is controlled by a microprocessor.
The microprocessor controls a radio frequency transmitter which emits signals to a receiver which
controls a hydraulic value. The hydraulic valve controls a push-pull arrangement which through a right
angle gear and pitch adjustment axial adjust the rotor pitch according to pre-programmed conditions
stored in the microprocessor. Waves are created by winds blowing over large bodies of water; tidal
changes in the sea are generated by solar and lunar gravitational forces. As the earth rotates, the
elliptical envelope shape of the ocean floor causes the water level to rise and fall. Ocean waves and
tides contain tremendous amounts of kinetic energy which could be harnessed to tum generators for the
production of electricity. Water is several hundred times denser than air, therefore, has more
kinetic energy per unit speed. This enorrnous power, if harnessed to generate electricity, is fuel costfree,
non-polluting, and self-sustaining. Furthermore, tidal currents are predictable for the indefinite
future; wave patterns are predictable for days in advance. Predictability is an important
characteristic for an energy source used in electrical generation which is inputted into an electric grid
where the supply equals demand.
SUMMARY OF THE INVENTION
The various types of power generation in several industries. It is clear that the dual purposes are
not designed.

DESCRIPTION
DETAILED DESCRIPTION OF THE INVENTION
A reversible wind turbine for coastal energy harvesting is an innovative renewable energy solution
designed to optimize power generation in coastal areas with frequently shifting wind patterns. Unlike
traditional wind turbines, which typically harness wind from a single direction, this turbine is built to
capture wind energy efficiently from both onshore and offshore directions. This capability is crucial
in coastal regions, where winds change frequently due to temperature differences between the land
and sea. The turbine features a bi-directional rotor and symmetrical blades, enabling it to operate
effectively without needing mechanical adjustments for each directional change. This design not only
improves energy capture but also minimizes wear and tear, reducing maintenance costs. Its
aerodynamic blades are crafted from durable, anti-corrosive materials, making them resilient against
the salty and moist coastal environment. Equipped with a permanent magnet synchronous generator,
