Performance and Generation of Electricity using Underwater Windmill

Abstract

Windmills are usually used to extract power from wind energy. Underwater windmills are used to extract energy from the water flow of oceans. Underwater windmills can also be called as Tidal stream turbines. They use kinetic energy of the moving water as wind blades use moving air. The principal of underwater windmill is same as the ordinary windmill. A set of blades creating a electrical energy converted from mechanical energy moved with the help of aqueous fluent of water. Tides are used to throw water against slanting blades and make them spin. Ocean has different currents at different depths. It was published in the article that near the seabed neither the whirlpools are consequent current passes in contrary direction. Towers can be built to extract power for such cases. Protection of sea life is also important. Underwater windmills have slow rotation because of considerable amount of solidity of water over air. Windmills can be put in the river superior ocean currents and can coat everything with Teflon or other slippery material.
