UNDERWATER WINDMILL
UNDERWATER WINDMILL2.docx (Size: 1.72 MB / Downloads: 314) ABSRACT The moon'sgravitational pull on water bodies creates tides. In turn, this movement creates kinetic energy that is carried by the water. Anything that moves has kinetic energy -- whether it's wind or a ball rolling down a hill. Kinetic energy can be captured by humans through windmills. Researchers are trying to tap into the power of the tides through a design similar to a windmill. Underwater (or tidal) turbines are a fairly straightforward concept, as far as cutting-edge energy technology goes. They are essentially windmills installed onto an ocean floor or river bed. The underwater current produced by the tides spins blades arranged like an airplane propeller. These turbines are attached to a gear box, which is connected to an electrical generator. This produces the electricity that is carried by cable to shore. Once it's plugged into an electrical grid, the electricity can be distributed. INTRODUCTION Imagine a windmill farm. Now, put that underwater, and then you have an underwater windmill or tidal turbine farm. Water, being denser than air (by about 800 times), is able to produce much more power than a wind turbine. In order to generate as much power, wind turbine blades need to be much larger than underwater windmill blades. Therefore, in the water, less is more when it comes to generating electricity. Tidal turbines and tidal farms are relatively new. They are being tested and implemented all over the world. Underwater windmills currently exist in the United States, the United Kingdom, Australia, Scotland, Philippians, Ireland, Wales, China, Russia, and more. HISTORY Frank Whittle in the mid-1980s invented the underwater windmill. During the Cold War, peaceorganizations were militating against nuclear developments while the Soviets were increasing theirnuclear systems. After the collapse of the Soviet empire,Russian public goods were privatized. Ancient membersof the party become the new owners of natural gasfields. They need to sell their natural gas to have thecash they urgently needed. In this context, theircompetitor was the nuclear power plants.In 1985, a little Danish windmill manufacturercould not pay his debt when the subsidies to theunderwater windmills were suppressed in US. Fortunately, newlong-term subsidies to underwater windmills are then granted inDenmark. A media campaign transforms nucleardangers, already publicized during the Cold War, in afrightening malediction. Another campaign waspromoting underwater windmills as saviours for the environment.Similar subsidies and campaign are granted in otherEuropean countries. Antinuclear pacifist militantsbecome antinuclear ecologists.Today, media campaigns are orchestrated, not bypublicity agencies but by underwater windmills. The descriptions of the operations of the underwater windmills are used as examples ofnew efficient propaganda methods developed during thewars. ABOUT UNDERWATER WINDMILL Underwater windmill works in principle, much like windmills, but driven by flowing water rather than air. They can be installed in the sea at places with high tidal current velocities, or in a few places with fast enough continuous ocean currents, to take out energy from these huge volumes of flowing water. These flows have the major advantage of being an energy resource which is mostly as predictable as the tides that cause them, unlike wind or wave energy which respond to the more random quirks of the weather system. THE BASIC TECHNIQUES TO GENERATE ELECTRICITY FROM TIDAL ENERGY ELECTRICITY FROM TIDAL ENERGY Tides are caused by the gravitational pull of the moon and sun, and the rotation of the earth. Near shore, water levels can vary up to 40 feet. Only about 20 locations have good inlets and a large enough tidal range- about 10 feet- to produce energy economically. The simplest generation system for tidal plants involves a dam, known as a barrage, across an inlet. Sluice gates on the barrage allow the tidal basin to fill on the incoming high tides and to empty through the turbine system on the outgoing tide, also known as the ebb tide. There are two-way systems that generate electricity on both the incoming and outgoingtides. UNDERWATER WINDMILL ELECTRICITY PRODUCTION The moon'sgravitational pull on water bodies creates tides. In turn, this movement creates kinetic energy that is carried by the water. Anything that moves has kinetic energy whether it's wind or a ball rolling down a hill. Kinetic energy can be captured by humans through windmills. Researchers are trying to tap into the power of the tides through a design similar to a windmill. CONCLUSION The Department of Energy has shown great enthusiasm regarding underwater windmill as one of the future energy source. Philosophy regarding energy will change drastically from the present into the future. In a society with increasing energy demands and decreasing supplies, we must look to the future and develop our best potential renewable resource. Underwater windmill fits the bill, a natural source of energy with many benefits. The planet's tidal capability greatly exceeds that of the world’s entire coal and oil supply. It is an ideal source of energy with great potential. When developed underwater windmills could be one of the type which provides energy for our future requirements.
