Wind power

Hurricanes Hurricanes are an example of nature’s greatest manifestations of God 's power and peace simultaneously. Throughout history, hurricanes have been recognized as some of the most violent storms ever recorded. A hurricane can be defined as, “ A violent, tropical, cyclonic storm of the western North Atlantic, having wind speeds of or in excess of 72 miles per hour.” Cyclonic storms are those with, “A system of winds rotating inward to an area of low atmospheric pressure, with a…

Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…

Historically the humanity has been conditioned to use fossil fuels and its derivatives, but the finitude of this natural resources incentive the development of new types of energy, mainly the renewable ones. In addition, the overwhelming of the atmosphere with carbon dioxide makes this new kind of energy a new hope because is commonly seen as the solution to the environmental problems. As a result, the benefits are considered the only point of view in many discussions about the theme, even…

confirm wind energy is the fastest growing power source in America, producing 4.4% of our electricity in 2014. In President Barack Obama’s 2015 State of the Union address on January 20th, he proudly proclaimed that, “America is number one in wind power” (qtd. in Gillin). Unfortunately, even as President Obama pushes for tax credits in the wind energy industry, many citizens as well as congressman are resisting the surge of “going green”. This struggle can be highlighted in the Cape Wind Project,…

Wind energy has been perceived as the next big energy source. Wind companies try to make consumers believe that this is the answer for the future, but research into wind energy demonstrates that coal or other forms of conventional power plants are needed. Coal plants have been shutting down due to the Clean Air Act, our country can not be sustained by wind energy. Some people speculate that nuclear should be the answer. Although wind energy is a well known renewable energy source, it has raised…

was caused by "straight-line" winds rather than tornadoes. Storms uprooted trees, destroyed buildings and caused power outages. More than 90,000 Appalachian Power customers in West Virginia were without power following the storm, and the company has asked crews from other states and companies of assistance in restoring services. According to the National Oceanic and Atmospheric Administration, "straight-line" winds are different than tornadoes because of how the wind damages objects. National…

comparisons as well as personifying ‘a cold November wind’ in an interesting way. The dictionary defines personification as “the attribution of human nature or character to animals, inanimate objects, or abstract notions, especially as a rhetorical figure” (Dictionary.com). In this particular instance, the wind is a blockade for Lutie, the main character, in her goals at the very beginning of the novel. On top of being a blockade for Lutie, the November winds are foreshadowing a lot of the…

However since a lot of people are paranoid, they will think that if they come that…

Tornadoes are rated on their destruction and the wind speeds. Second, the major destruction that tornadoes cause can be very deadly. The major destruction that tornadoes cause effects people’s lives, animals, and their habitat. Tornadoes also effect the environment by harming “the food chain…

Hurricanes Hurricanes are monstrous, large, swirling storms, with huge and strong winds. They are one of nature’s most deadly beauties, which that can blow up to 252 km pr hour(157 mph or more) which is similar to the speed of some high-speed trains. The storms form over warm ocean waters while also able to strike land. When the hurricane reaches land, it will push a wall of water ashore. That water is called a storm surge, and along with the rain, the hurricane can also cause some deadly…
