Monsieur Girard's The Oscillating Water Column

Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.

At the start of my journalistic investigation I stumbled upon a 2010 documentary by the explorer Wes Skiles titled Water’s Journey. The short film is available online free of charge and follows a scientific team of four as they traverse the Florida aquifer in real time. The goal of their mission was to explore and extensively map the inside of the Florida Aquifer for the first time. The four individuals on this groundbreaking mission included Tom Morris, a cave explorer and biologist, Jill Heinerth, a technical dive specialist, the Wes Skiles, and electromagnetics expert Brian Pease. Pease designed a revolutionary transmitter that was able to send signals through Florida’s solid rock and water below, which allowed for him and Skiles on the surface to actively track Morris and Heinerth as they explored the depths below.

1. tidal water trapped behind coastal barriers in bays and estuaries can be used to turn turbines and generate electrical energy.

Weather is created by the movement of air masses of different temperature and moisture content moving around the Earth’s atmosphere and interacting with each other.

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.

Dabiri of California Institute of Technology associated with aquatic bio forms. Wind turbines are the Colossus of the modern landscape and the blades can sweep up to a football field in diameter. Critics call this particular invention unsightly while the blades clobber unsuspecting birds. There is also an a efficiency problem while the blades become more powerful, but they’re size requires that they be spaced apart, this means they take up a lot of land. John Dabiri of Caltech also found a solution underwater and also built an experimental wind farm-(FLOWE). In which the location of turbine relative to each other takes advantage of air flow among them” Dabiri 1. “The turbine placement was determined by studying the wake vortices produced by schools of swimming fish” Dabiri 1. Dabiri’s 30 ft. tall wind turbine has blades that gather energy generated as wind flows through the wind farm. The blades take advantage of the wind’s behavior, for energy production, the way fish take advantage of water’s behavior for forward

“Matson Navigation Co. spent $14 million to make its diesel-powered ships more environmentally friendly. The Honolulu-based company goes through the Port of Long Beach to bring supplies to Hawaii.” Even though Matson Navigation Co. is trying to erase their environmental footprint many people go out into the world and pollute it, some do not know, do not think about it, or just do not care. If people think or try new ways to make the world a bit cleaner, or just lower the percentage of pollution each year the Earth could become so much nicer and cleaner. To work with energy, there are many ways people can, first they could help make cleaner

"Numerous engineers contributed to the refinement of waterwheel construction, and by the middle of the 19th century new designs made possible increases in the speed of revolution of the waterwheel and thus prepared the way for the emergence of the water turbine, which is still an extremely efficient device for converting energy." (Buchanan 3).

Whales are massive aquatic animals yet, despite their weight, move swiftly through the water. They can do that because of the ridges on their fins. These ridges are called tubercles and allow whales to move through the water smoothly. If engineers could take this idea and incorporate it into a wind turbine, it could potentially make wind turbines produce more energy. The reasoning behind this theory is that animals are always evolving and adapting to the environment, so if researchers are

One resource that is essential to produce electricity is renewable energy. Providing one’s own energy consists of utilizing solar panels, wind turbines and micro hydroelectricity. Solar panels absorb energy from the Sun to produce solar energy. A great number of people who live off the grid use solar power. Wind turbines generate electrical power from the wind and functions in the reverse manner as a fan does. Micro hydroelectricity is another source of energy, which fascinatingly “uses a source of running water, like a stream, to generate electricity” (Dunn 3). Between all three sources of renewable energy, micro hydroelectricity is the most efficient, reliable and commonly used form.

Along with these benefits come many practical difficulties associated with offshore wind projects. Offshore projects are expensive, particularly when paralleled with those projects which are land-based. The surface of ocean is a harsh place to maintain and build these structures. Due to this reason, high winds that carry larger amounts of energy threaten the steadiness of wind turbines which causes installation to become much more rigorous and costly. Furthermore, it also fetches the need for monitoring which is an expensive and automated system for maintenance. Underwater topography presently describes the viability of installation as most current models use foundations rooted directly into sea beds that are shallow.

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

We have many different kind of energy source in our world and the ocean is a big part of one of thought energy source. The ocean makes up more than 70% of the Earth’s surface and it collects a lot of sun’s heat and energy. This will make it the “world’s largest solar collectors and energy storage system” and the Ocean Thermal Energy Conversion (OTEC) will probably seems like a great tool to have [7]. This energy source works is by using the solar energy collected from the sun by the ocean and converting that energy into electric energy. The OTEC uses the warm ocean water that was heated up from the sun (around 77 degrees Fahrenheit) to vaporize a working fluid with a low boiling point. The working fluid expands and spins a generator, creating electricity. From there, the vapor is then cooled down from the cold ocean water (around 41 degrees Fahrenheit) that is pumped up from the deep parts of the ocean layer. This cause the vapor to turn back into the working fluid from before and condenses back into a liquid. Because of this, the whole system is reusable and is a continually electricity generating cycle [7]. This is only one type out of three OTEC systems, known as closed-cycle system. The other two systems will be explain later on in the paper. This paper will explain different aspects of the OTEC systems, from the different types that are currently being used to the costs and environmental effect to the pros and cons of the OTEC systems.

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

The SAARC region with over a billion populations is contiguous to the Indian Ocean, Bay of Bengal and the Arabian Sea. Utilization of ocean resources for power generation such as tidal, thermal solar and wind for energy, along with other green technologies like seaweed farming and sustainable fisheries for food would need to be incorporated in a broad framework for the region. Development of ocean-based energy systems can be integrated with early warning networks linked by satellite which can give a few hours to days warning to help mitigate the severity of natural disasters on human life. . Some of the calamities of note have been the Tsunami of 2004, Bangladesh and Orissa floods, earthquakes in Nepal and Pakistan, and recent inundation of Chennai due to weather and bad flood management. A SAARC comprehensive Framework on disaster management was formulated in alignment with the Hyogo Framework (2005-2015). In addition to the broad objectives of disaster management and cooperation in the Indian Ocean and surrounding regions, impeding disasters due to climate change need to be anticipated. Ocean energy systems are still in their infancy, while ocean
