Hanging 10 for Power Generation
There are many different ways to generate electricity. Wind, rivers, fire, and ocean are just a few technologies that are in current use. In this paper it will narrow the focus to the different types of ocean wave power generation.
Wave generated electricity is a fairly new concept. Heavy research started in the early sixties. People have been trying to build effective wave machines for about two hundred years. Designing wave machines can be difficult do to the nature of the ocean.
One of the primary set backs in designing wave technologies is the inconsistencies of the ocean. The tides, wave height, wave set counts, and consistencies are major hindrances

As the water level inside the chamber raises and lowers, the difference air pressure turns a low resistance turbine, generating power. The turbine spins in one direction no matter if the air is pulling or pushing. The collectors have been design in this manner to obtain the maximum output of power out of the machines. Most of these wave collectors, also known as oscillating water columns are still experimental. This device is regarded as the world most advanced wave-to-electricity generators. An oscillating water column in Norway is being tested and can produce 500 kilowatts of electricity.
A “Salter Duck”, is another invention that has been developed to produce power from waves. This machine is basically two large pontoons hinged together at their ends. The bobbing action of the pontoons gives the mechanical advantage to drive the internal generator. This was the first invention to receive wide spread use to make ocean generated power. The United States Coast Guard has been using many of these to power generating tools for their navigation lights and audio transmitters.
Another type of energy the ocean has to offer is her tides. Generators used to harness power from ocean tides are the cheapest to build. This is for the shear fact that most of the tide power stations are connected to land. Due to logistics it is a lot easier to build objects closer to land than in the middle of the ocean. These power stations can
Water turbines are near the oldest ways to run power without using fossil fuels. The new age had turned these into hydro turbines that generally reside in dams. These machines take similar shape to wind turbines. Hidden in the base of a dam, there is a very large turbine that, in a simple explanation, when water runs through it spins. With the energy used by the spinning turbo it is turned into different power sources that are stored into power cells. Way back in time, this idea was used in power mills. Those old spinning wheels on the side of houses that rotate with water pressure. The first power plant was constructed in 1879 at Niagara Falls, Canada. In the United States the first plant was in 1882 in Wisconsin. These extravagant machines seemed marvelous, but that is no longer the outcome. The current age hydroelectricity dams are currently being shut down for harmful aspects triggered from the giant production. Causing an environmental failure to marine life and habitats all around. The possible outcomes are: changing the oxygen levels in the water that cause organisms to perish; fluctuating water levels that cause different
1. tidal water trapped behind coastal barriers in bays and estuaries can be used to turn turbines and generate electrical energy.
Wind turbines are another common way to power things. They are usually made to power a city and many are needed for a lot of energy to be created at once. Wind turbines are made to be very tall because that the higher up you go, the windier it gets.
Humans have made significant discoveries in utilizing the countless benefits of water, one of the most important being the ability to use water to perform work. This is the concept of hydropower. Hydropower is using the energy of moving water to create power. This clean and renewable method of power generation is used all throughout the globe, and accounts for a small percentage of global electricity demand. Hydropower hasn’t always existed as the large scale dams that are abundant today. Hydropower technologies have been slowly evolving for many centuries.
Although Wave Dragons have shown to be detrimental to the environment around them, there are more options and ways to use wave energy while having little effect on the ocean and the aquatic life in. From the Pelamis system which can be most efficient in areas with high wave activity to the oscillating water column devices, there are many different options on how to efficiently and safely utilize wave energy. Scientists are continuing to explore and research current methods as well as experimenting with new technologies in hopes of using wave energy as a renewable
The Oscillating Water Column (OWC), is a device which is descended partially into the water allowing for the raising and lowering of tides to generate kinetic energy upon a turbine, the Surface-following attenuator produces energy through a series of floating units, which are suspended along the surface of the water, these units follow the movement of waves generating energy, lastly, the Buoyancy Unit floats above the water and generates electricity through upwards and downwards movements. These methods are currently being exceedingly researched, yet not completely enveloped by the masses. Wave energy is currently in its infancy as public concern of wave and wind shifts, endangerment to various aquatic species, and ceeding lethargic an already tedious process. Yet, as the masses ease from the pernicious fossil fuels, renewable energy sources are mandatory towards the progression of humans, which must be harnessed from nature in it’s purest
It was only in the 19th century that the process of using falling water and revolving turbines to make electricity was announced in the U.S. and Europe. And it has only been since the 20th that these sorts of processes have been retooled for building along coasts and not just rivers.
Waves are produced by winds blowing across the surface of the ocean. However, because waves travel across the ocean, their arrival time at the wave power facility may be more predictable than the wind.In contrast, tidal energy is driven by the gravitational pull of the moon and sun. Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity. Tidal power has great potential for future power and electricity generation because of the massive size of the ocean [29][30].Tidal power has a relative advantage in that it can generate power from
This has led to significant tidal energy potential being identified in the UK, in particular Scotland, Cornwall and Wales, that offer prospect of building large scale turbine farms or barrages to harness tidal energy. New research has indicated that the UK is severely underestimating the amount of energy that could be generated from tidal sources and that a tidal barrage would be expected to generate 15% of the UK’s electricity needs, according to the BBC, (2013).
Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.
If less than one-tenth of one percent of this stored solar energy could be converted into electric power, it would supply more than 20 times the total amount of electricity consumed in the United States on any given day ("Ocean Thermal Energy Conversion"). Imagine just a fraction of the oceans energy found just in temperature can be used to power the world. Some already have and such technologies have been created to suit the need to obtain this elusive power. However, huge turbines are needed to take and create the power from the temperature. These huge turbines can be used in different methods to
Moving water can generate energy, which is called the hydropower. Hydropower is a main renewable energy which produces 20% of the total electricity-generation in the world. It is also a green energy which will not emit carbon dioxide. If hydropower is used in appropriate way, it can be considered an unlimited energy. Unlike nuclear energy or solar energy, humans have used water as energy for a long time (Ngo and Natowitz, 121). The technologies are sophisticated and worth spread worldwide. Besides the renewable energy and new energy mentioned above, wind power and geothermal power are also contributing to a healthy energy market. Germany generates their energy by not only solar energy and hydropower but also wind power and geothermal power which are much cleaner for environmental and human health.
Ocean Thermal Energy Conversion (OTEC) is an energy innovation that changes over sun based radiation to electric energy. OTEC system utilizes the sea 's regular warm angle the way that the sea 's layers of water have diverse temperatures to drive a force creating cycle.Exploratory and legitimate studies have been carried out to center the qualities of the temperature andwater and the cool profound water varies by around 20°C (36°F) [1], an OTEC cycle can create a lot of force, with little effect on the encompassing environment. The unmistakable highlight of OTEC energy system is that the finished items incorporate energy as power, as well as a few othersynergistic items. Force is changed over to high voltage DC, and is cabled to shore for
Most of the technologies and devices for wave energy are still oriented to be installed at or near the water surface. Some of the most popular wave energy technologies are: (1) Point absorbers that uses floating structures with components that move in proportion to each other because of the actions of the wave and its energy is produced by this movement that powers electromechanical or hydraulic energy converters. (2) Attenuators are uses
It contain all the necessary components which are fulfilling the need of our primary need of project through which we can able to collect and gather all the desired energy from the sea through our unique way and design to collect and generate electricity in an efficient and smart manner.
