Science Fair Project: Alternative Energy

Over the last few decades, the loss of Louisiana’s coastal wetlands has become a point of concern because of the vital roles the wetlands play in the environment. They have been destroyed over time because of natural causes such as hurricanes and weather as well as from the construction of man-made flood-control levees. Wetlands serve many purposes within the environment. Not only do the wetlands effect the residents of southern Louisiana, but they effect the animals that call the wetlands home as well as the industries that thrive off the wetlands. Since the wetlands have begun to disappear, steps have been taken in order to prevent Louisiana’s wetlands from disappearing. Restoration acts have been put in to place by the government to help

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

Hydroelectric power works but having a turbine placed in moving water. The water that rushes past the turbine forces the turbine to move and spin this creates electricity and the fast or bigger the turbine the more electricity that is created. Once the power is created by the turbines turning it is sent out through power lines to either power plants to store the electricity or to homes and building to power them.

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

The energy pathway of tidal energy would begin with having gravitational potential energy that is caused by the celestial bodies and their gravitational pull. The water would then have acceleration and kinetic energy from the wind. As the water makes contact with the turbines kinetic energy is released to propel the turbine. The

"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).

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.

Have you ever went to a location and looked at the environment? Could you automatically tell by the surrounds what type of social class or government it fallen into? Have you ever been to an unknown discovery? Have you ever wondered where the earliest Indian civilizations emerged from? Did you ever know why the “Nile River Valley,” or, “Indus River Valley,” are very important to civilization?

In novel “Animal Farm” by George Orwell, he mentions the animals in the farm they all have the vision of freedom after Old Major’s prediction. They rebilled against the farmers and after their victory they tasted the revolution. The farm was renamed “Animal Farm” and made the constitution of the manor – “the seven commandments.” Soon there is a split on the revolution between the pigs, Snowball was declared as an enemies of the revolution. Since then Napoleon and Squealer obtained the leadership of the farm, immediately they have more power and more preferential treatment, they gradually moved away from other animals, and eventually become exploiters for exactly the same as humans, the original ideals of animal farm name is also be abandoned. One theme of animal farm is that we need to have a clever mind to see through unfair trick, before it is too late.

Similar to a dam, overtopping gadgets (see fig. 4) feature basins into which inward bound waves enter and cause a small upsurge of pressure. After it is released, water streams back into the sea through gravity. The retreating water releases energy that is utilized to rotate hydro turbines and to create power. By channeling waves through in-house turbines that later release water into the ocean, special floating podiums may as well generate electricity.

To elaborate, dam is one of major parts to discuss about firstly. The process of a dam is to store water by creating a large reservoir. This reservoir could be a lake or any other natural water source. The dam is most likely located at higher level ground than the turbines of the power plant. The dam contains gates at its bottom to control the water flow. As the gates open, the water stored in the dam flows downstream as gravity pulls everything down or towards the earth’s surface. The falling water goes through a pipeline called penstock. This pipeline leads to the turbines in the hydroelectric power plant. Much water flow in the pipeline means greater pressure from water. As the water comes down the pipeline, it hits the blades of the turbines and makes it rotate simultaneously. The speed of the rotational blades depends on the speed of the water flow. As a result, much pressure of water flow will rotate the blades with a higher force and vice versa. Francis Turbine is the turbine that is most common for building hydroelectric power plant. This type of turbine looks like a big

Renewable energy is crucial to the future of human society, as it takes from sources that cannot be depleted, such as the wind , waves, and the sun. However, the production of renewable energy is not steady and often exceeds its demand. The excess energy created is often wasted, while renewable energy would prove most effective if it were able to be stored. This would allow renewable energy to be used less in times of low demand and saved for greater use in times of high demand. A recent innovation has been developed to solve this problem: the wind bag. Using compressed air, the wind bag will store and conserve renewable energy, maximizing the productivity of using the water and wind as sources of energy. By analyzing newton 's second law of motion and centripetal acceleration, mathematical equations for wind turbines, offshore wind farms in Belgium, the use of compressed air to store energy, and the aspirations of RWE Power in Germany and the European project AA-CAES for the future of using wind bags for the storage of renewable energy, it is conclusive that wind bags are beneficial to the future of human society and are personally significant to each and every one of us.

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.

Gas turbines, internal combustion engines methods for small generators have been perfected and are widely practiced and others renewable resources like water, wind solar energies are also finding wider application in recent years.

In order to generate electricity from the kinetic energy in moving water, the water has to move with sufficient speed and volume to spin a propeller-like device called a turbine, which in turn rotates a generator to generate electricity. Roughly speaking, one gallon of water per second falling one hundred feet can generate one kilowatt of electricity.
