Thermal Energy Conversion Essay -- physics energy power renewable powe

The demand for an efficient renewable energy source is a driving force in ongoing research. Thermal energy conversion is one such potential source that is under constant investigation and has endless avenues of possibility. The two requirements of energy production are efficiency and renewability. Many possibilities exist for energy production including: Fossil Fuels (natural gas, oil, coal, oilshale), nuclear, solar, wind, geothermal, biomass and wastes, & hydroelectric. Efficiency of the use of these resource are directly related to the location and the demand in that location. For example Hawaii is a prime candidate for the use of the oceans mechanical wave action, the thermal gradient of the ocean, wind, and biomass from the high levels of plant growth. The demand for another energy source comes from Hawaii's dependence on oil that has to be transported there. Ocean Thermal Energy Conversion Ocean Thermal Energy Conversion(OTEC) is the utilization of the energy stored in the world's oceans by the thermal gradient created. The thermal gradient is the difference of the surface temperature of the ocean that is heated via solar energy and the water at depths of significantly colder temperatures. This thermal gradient is the energy source that is converted to usable energy by OTEC plants. The idea for using the oceans thermal energy is credited to several visionaries including Jacques D'Arsonval, a French Engineer, in 1881. The temperature difference needed for an OTEC plant is about 36 deg F (20 deg C). Temperature differences of this amount are readily available in many locations in the world. The areas depicted in red on the above map produce the best areas for OTEC sites due to the stablility of warm weather throughout t... ...ntially be exploited for one of the municipalities that stand beside the pipeline? Arctic North Slope Borough - 179.2 mi. Fairbanks North Star Borough - 89.1 mi. City of Delta Junction - 5.5 mi. City of Valdez - 20.8 mi. Could the pipeline at least help to power one of the ten pump stations located along its winding path? It is not likely that the heat exchange in either of the two above systems would produce a sufficient enough amount of energy to produce electricity. The temperature of the oil as it is extracted is approximately 160 Â ° F and the flow temperature approximately 140 Â ° F. These temperatures need to be maintained for the oil to remain in a viscous enough state to be transport with some amount of efficiency. This inquiry into the potential use of excess heat being produced as a by-product does however open the door to other possibilities.

Analysis of the Movie “Jose Rizal” Essay

A three-hour epic on the life and struggles of poet and patriot Jose Rizal, the national hero and martyr of the Philippines, this film was commissioned to mark the 1998 centennial of the country’s independence from Spanish colonial rule. Rizal was a remarkably educated man; not only was he a writer, but he was also a painter, sculptor, doctor and surgeon, teacher, natural scientist, economist, engineer and theologian. He was an excellent fencer and marksman; he studied at colleges in Europe, America and Asia, traveled to many different nations and could speak twenty-two languages. He was a champion of his country’s independence, a Filipino Gandhi who faced the firing squad at the age of thirty-five for inciting rebellion. He was the instigator of the Philippine revolution of 1896-98, the first national uprising against a colonial power in Asia. He also wrote two books, Noli me tangere and El Filibusterismo, which sought to increase his people’s political awarenes s. Director Marilou Diaz-Abaya deliberately avoids a historical lesson. The Rizal of her story Cesar Montano is thinking back on his life and writings from his prison cell in the fortress of Santiago; the characters that appear are a blend of the real people, friends and enemies as well as those he created in his books. The script is solid, with a contribution by Diaz-Abaya’s long time collaborator, Ricky Lee; the soft tones of the cinematography helps to create an atmosphere of magic appropriate to the story of a legendary hero, and the acting by Cesar Montano is quite remarkable. The movie begins in 1891 with Jose Rizal, played by Cesar Montano, as an established author and linguist who speaks more than 20 languages. He vows to write about the sufferings of the Filipino people under the tyranny of Spanish rule, and about their abuse by corrupt priests. Rizal’s writings galvanize the Filipino people but earn the scorn of the Spanish government, which vows to crush the reb ellion of the Filipinos. The Spanish military capture and torture Jose’s brother Paciano, played by Pen Medina, to determine Jose’s role in the rebellion. During a flashback, Jose says Paciano greatly influenced him by exposing him to the injustice going on in the Philippines. Paciano is released after his interrogation and returns to Manila, where the family plans to go on the run. An order is given to arrest Jose Rizal on sight. The movie cuts back to Jose’s childhood, when he was called Pepe. When he is a child, his mother is falsely arrested for attempted murder and jailed for two years. He gets attention from educators early on for his intelligence and writing prowess. As a young man, he criticizes a college professor for stating that Spaniards are superior to Filipinos. Filipino students start fighting Spanish students after Jose starts raising the issue of Filipino independence. Cutting back to 1896, Jose is captured and put on trial, and his books are banned. The film then cuts back and forth between Jose’s rise as a revolutionary and his fall from grace during his trial. As a student, Rizal spent significant time in Madrid but then became disgusted with Spain’s occupation of Filipino land and Spanish treatment of Filipino citizens. The mayor of Madrid is arrested and discredited for having a Rizal book. A violent revolt breaks out in 1896, which Jose does not support because he sees it as mass suicide. Going back to the trial, enormous pressure is put upon Jose’s defense attorneys, with critics branding them as traitors for defending the rebel. It is revealed in a flashback that Jose had fathered a child that had died soon after birth, adding to his inner turmoil as he buried his only son. In the trial, his books are examined and criticized for their pro-Filipino stance against Spanish imperialists. He is found guilty of staging a rebellion through his speaking and writing, and he’s condemned to death by firing squad. He sneaks a poem to his family before his execution, and he yells â€Å"It is done!† A full-blown rebellion is soon under way. Two years later, in 1898, the Filipino flag is lifted triumphantly as the citizens celebrate their independence.

The City Of Southern Mexico Los Lobos Meaning The...

There once was a small village in Southern Mexico called â€Å"Los Lobos† meaning The Wolves. The village was named that because the hills that the village were built on, it was inhabited with wild wolves and the people had to be careful where they went. A family was going down there to visit their relatives including Bryan and his nephew Miguel. They were very excited since it was their first time visiting Mexico, but it all changed once they got closer to the small village which was filled with dirty streets and homeless families begging for food. The sad scenery looked like something you would see only on T.V, but it was worse and the saddest thing he had seen. They finally arrived in the state of Guanajuato where the village was at. They†¦show more content†¦The house had an unusual smell to it that Bryan couldn’t quite his finger on it. Miguel had never minded any of the people in the village had always believed the story ever since they were a young child , but there showed no evidence of this so called â€Å"Witch†. old lady on the corner of Babylan St. because he always knew it was just a folktale,so they wouldn’t go into a stranger s house. Many of the old people in the village had claimed they had been marked by the witch when they were little while sleeping in their very own homes including Bryan’s Grandma Mrs. Ojeda. The family was enjoying their first chilly night under the stars that were clearly visible unlike how they were back home. It was a perfect time for Bryan and his nephew to ask their grandmother to tell them the story of the witch on the corner of Babylan St. that was just 4 houses away. Bryan finally broke the silence of the night by telling his grandma, â€Å" Grandma can you tell us the story of the witch on the corner of the street?† Bryans Grandma had agreed but told us not to tell their parents she had told them the story. She said,† The rumors began when a family had moved into the house a week before Christmas. Time had passed and the day was Christmas Eve and as traditions went, they would blow fireworks starting at midnight and burn the dummies they had made of hay and firew orks with old clothes they saved all year. The family did not want to do fireworks that night so they stayed inside the house for
