With approximately eighty percent of our energy, according to the U.S. Energy Information Administration, still being manufactured from fossil fuels that release pollutants to the air such as greenhouse gasses that include carbon dioxide, nitrogen oxide and methane, it is not a bad idea to consider some alternative energy options like wave power. What is wave power? It is the harnessing of power of the ocean’s waves by using the momentum of the waves to power a turbine. There are several models that are effective for it’s respective region. The potential of this option is great because of the vastness of the ocean and how it could very well be an inexhaustible source for the future.
To produce more energy efficiently, there are several models designed to absorb as much energy as possible. One example includes the oscillating water column. This model has two openings, one on the bottom for the water to enter and another narrow passage that allows air in and out a chamber that contains a turbine. The water comes from the bottom and pressurizes air, forcing it to go through the narrow passage spinning the turbine. When the water is on its way out, the air comes out through the narrow passage thus spinning the turbine again. Another one is an overtopping device. This device is a reservoir where there is an opening on the top for a turbine outlet. It is meant for when the waves topple over the reservoir the water goes down the opening which, in turn spins the turbine. The Pelamis sea snake are “snake-like” buoys that are tethered together with rotation devices that use the wave’s horizontal force to produce rotation energy.

- By using the endless power of ocean waves, endless energy can be created. Wave power plants have a simple, yet practical way of harnessing the endless energy that ocean waves provide. Although the development of harnessing this renewable source of energy is still in its infancy, many predict that this underdog of a resource could be used worldwide in the near future. Wave power plants are able to harness renewable energy by using the ocean's waves. There are several different types of wave power plants, but most behave in a similar way....

- Feminism can simply be defined as a range of movements and ideologies in which share a common ground in terms of defining, establishing and achieving equal opportunities to that of males, in regards to economic, cultural and social rights. It is a critique of male supremacy with efforts in changing this to end the social oppression of women. (Hooks, 2000) The first wave of feminism is more commonly known as the women’s liberation or women’s suffrage movement. First wave feminist’s main concern was in political power especially in terms of the right to vote, having a voice.... [tags: Feminism, Women's suffrage, Third-wave feminism]

- As Third Wave feminism is currently unfolding before us, and its aims encompass a wide array of complex issues, it is often hard to describe what Third Wave feminism is. The feminist theories, mainly associated with First and Second Wave feminism attempt to describe the power imbalances that are found in society, and while doing so expose other oppressions, such as discrimination based on race or sexual orientation. As this essay attempts to place a clear definition to Third Wave feminism, feminists are concurrently trying to deconstruct old definitions and open it up for women to determine what feminism means to them....

- Introduction On March 11, the strongest ever instrumentally recorded earthquake in Japan struck its northern coast. Ground shaking triggered the safety shut-down of 11 nuclear reactors and cut external power supplies to the Fukushima Daiichi nuclear plant complex. Located on the coast just southeast of the earthquake’s epicentre, the Fukushima plant withstood the ground motion but its back-up power supplies from diesel generators, needed to keep its reactor coolant pumps working, were disabled by the impact of a following 14-metre tsunami wave....

- The time period after colonialism called for Africans to unite and prosper. The events leading to independence created a new wave of ideology. African socialism, African nationalism, irredentism called for new interaction between the Africans and the European powers that governed them. The evolving role of Africans leaders saw them taking back the power that was snatched from them by the Europeans. It seemed that Africa was deemed to experience a bright future. The new ideologies that emerged with the independence of African countries came with the thoughts of educated African elites.... [tags: Africa, African Union]

- So I received my invite to Google Wave one week ago, and have been playing with it off and on since then. It’s a fascinating platform, not quite what I expected, and it’s been really interesting to think about potential applications and uses of the platform. My initial impression upon logging in was that it was a typical Google app, visually very clean, colorful, and smooth. I had some idea of how things worked from watching their tech demo video, so I began to play around with creating and joining waves.... [tags: Information Technology]

- As a fourth wave feminist of color, black feminism means many things to me. It means that I have many opportunities available to me that the first, second, and third wave feminist did not have. It also means that although we as women of color have been fighting for equal pay, equal rights and equality in our relationships, that we still have a long way to go. Before I took this course, I thought that feminism was about equality, fighting, and power. When it comes to equality, I thought about being on the same level as men in every aspect of life....

- Windows 7 Migration and Zen Replacement Project Wave Hello everyone, I decided to modify this wave to focus on the Windows 7 migration. Let's test this platform out as a collaboration tool and see where it takes us. The Windows 7 migration is an extremly complex and far reaching project and I hope Wave within our Apps domain will allow us some cutting edge tools to communicate. First of all, I will outline my vision for our desktop enviornment and give updates on where we stand with our next generation infrastructure.... [tags: Business Management]

- The Oregon coast is 363 miles long and has powerful waves and consistent winds. This makes Oregon’s coast a good candidate for establishing hydrokinetic energy facilities. Hydrokinetic energy is energy created from the movement of water, in this case, wave energy. Wave energy is the energy created from the movement of waves that is captured by a device that converts the movement of waves into electric energy. Although wave energy can help the environment, it can also cause harm. Oregon can reduce the amount of harmful environmental impacts caused by wave energy devices by limiting their location to areas that will have the least impact on marine ecosystems....

- Debating Whether Nuclear Power Should Be Developed for Future Energy Supplies Introduction I am writing this essay to debate the idea of having nuclear power developed for future use by us. This takes on a major issue and covers many aspects of our nations energy use both in present and for the future. When we think about nuclear power we do not automatically think of it as a non renewable energy source. This is because it is not part of the fossils fuels; coal, oil and gas, which we all know will not last us as reliable energy sources for much longer.... [tags: Papers]
