Reviews Existing Technologies and Proposes ‘E8-PowerBuoys' Nano-Scale Generator Of Tidal And Wave Energy For River And Ocean

The installing and generating capacity of sustainable energy dramatically increasing since 2009. It can be noted that none a single sustainable energy technology will be able to achieve the carbon reduction independently. The simultaneously developed of many sustainable energies still needed. The recent growth in sustainable energy, especially tidal and wave energy is shown that the nano-scale generators for the river and ocean are still required. This is due to the most country in the world have the river and the ocean covers approximately 70 % of the surface of the earth. In practice, the tidal energy is the interaction between the gravity of the sun, earth, and moon, and hence it results the rise and fall of the tides. Whereas, the wave energy is the water movement due to the frictional drag of wind over the water surface. Despite these advantages, tidal and wave energy continued to face challenges in achieving a high efficiency output to generate the electricity, Moreover, some standards and regulations of grid connected are needed to revise in order to ensure its operations and safety. These allow small-scale distributed generator such sustainable energy resources to cooperate with the exiting power network. Therefore, the paper reviews and proposes the nano-scale generator of tidal and wave energy for river and ocean. The proposed generator can support at the riverbank, in the middle of river, bays, shoreline, coastal estuaries, and in the middle of ocean. The generator should be easy to install and maintenance, while the chosen material structure of generator has the corrosion resistance of the saline water. The generator must follow the standards and regulations in order to ensure its safety.
