- Alternative Cinema - 1,558 words
Alternative Cinema The term alternative cinema has certain connotations. To many, it is not alternative, instead it is the way cinema was meant to be viewed, in that the viewer should be able to define the film in their own personal terms. In the following essay, I will firstly examine what the term alternative cinema means, and secondly how Brechts theories are evident in many elements of the films that have been pigeon-holed as alternative cinema. The word alternative is described in Collins English Dictionary as: "Denoting a lifestyle, culture, art form, etc., regarded by its adherents as preferable to that of contemporary society because it is less conventional, materialistic, or institu ...

... w used to locate oil deposits on land and in deep offshore fields. Two major new sites that are being tapped for oil is the Gulf of Mexico and offshore of West Africa. In the Gulf of Mexico 5.9 million acres off of Alabama and the Florida panhandle will be sold for development by December 2000. Areas around this huge plot have been drilled, but the new developments mean that we need to expand our search and extraction of oil. The seas off the coast of Nigeria (Africas biggest oil producer) is another major site for new development. Triton Energy made a major discovery on the southern part of a 125-mile long strip of undeveloped oil fields. Technology of drilling in offshore wells has adv ...

- Bush And Gore: The Issues - 796 words
Bush And Gore: The Issues Presidential elections have taken place every four years for more than two hundred years. This year is no exception. The forerunners in the 2000 elections are Governor George Bush (Republican) and Vice President Al Gore (Democrat). These candidates have strong and different views on many issues such as crime, abortion and energy. Crime is a major concern of all American citizens and has been addressed by the majority of candidates in past elections. Voter.com, a web site designed to keep voters informed on the candidates and their stand points on different issues, state that "Al Gore believes that there is no more fundamental responsibility than to make Americans sa ...

Chernobyl La era nuclear empieza a partir de la Segunda Guerra Mundial, a 50 aos de este suceso histrico, dos ciudades nuevas se han levantado de las cenizas atmicas de esta catastrfica guerra. En una de estas ciudades, Chernobyl, a diez aos de la explosin nuclear, poblaciones enteras han sido abandonadas alrededor del reactor destruido, para escapar del agua y del alimento contaminados producidos en el suelo que una vez fuera rico. En el mismo perodo desde la Segunda Guerra Mundial, la mayora de los bosques tropicales fueron destruidos. Se encontro una declinacin dramtica en las especies de plantas y de animales. Los antroplogos registraron una catstrofe global tan enorme que probablemente ...

- Electric Cars - 855 words
Electric Cars In numerous cities across the country, the personal automobile is the single greatest polluter, as emissions from million of vehicles on the road add up. Car pollution is one of the biggest polluters the solution is to have much more efficient vehicles that produce fewer emissions with every mile. So what would be the best thing for cars to run off of in the future? Electric vehicles are the answer to this problem. Electric vehicles or EVs, are vehicles that are powered by an electric motor instead of an internal combustion engine (Frequently). EVs use electricity as the "fuel" instead of gasoline or some other combustible fuel. The power for the vehicle is stored in many large ...

- Environmental Activism - 1,283 words
Environmental Activism $115 Designer Cosmetic Collection From Cosmetique -- Only $1! Environmental Activism 1. The large mainstream environmentalism groups started to compromise too much with regulatory agencies and bureaus, starting with the Glen Canyon Dam project. This began an estrangement with the mainstreams that culminated in the rise of more militant groups like Earth First! Glen Canyon represented what was fundamentally wrong with the country's conservation policies: arrogant government officials motivated by a quasireligious zeal to industrialize the natural world, and a diffident bureaucratic leadership in the mainstream environmental organizations that more or less willingly coll ...

- Geothermal Energy - 553 words
Geothermal Energy Geothermal energy represents the inner heat of the earth, produced largely by the decay of radioactive elements in the mantle and center. The three ways that the heat is found is both wet and dry steam (wet steam has drops of water in it), hot water and dry volcanic rocks. We know that the temperature of the earth at depths of 25 to 50 km range from 200`C to 1000`C. There are areas of the earth where local concentrations of heat occur, just as mineral concentrations do. Most of these are located along oceanic ridges and continental rifts, such as the Ring of Fire. Geothermal energy is not free from environmental problems. The steam contains large amounts of hydrogen sulphid ...

Global Warming Meghan McDonald McDonald 1 Mr.Hrkal OAC World Issues December 18th, 2000 Global Warming Now, for the first time in Earth's history, humans may be a decisive factor in future climate change. The actions we make towards the temperature of the earth and the depletion of the ozone layer are irreversible. A warmer future could result from present-day human activities releasing large amounts of heat-trapping gases into the air. These greenhouse gases are part of the reason for the 1F (.5C) rise in global average temperature documented over the past 100 years. If the Earth's temperature continues to rise as predicted, future global warming could happen faster than any climate change ...

- Solar Energy And Its Social Consequences - 664 words
Solar Energy and Its Social Consequences To understand the social consequences of solar energy, one must be aware of what solar energy is. Solar energy is a radiant energy produced in the sun as a result of nuclear fusion reactions. It is transmitted to the earth through space in quanta of energy called photons, which interact with the earths atmosphere and surface. The strength of solar radiation at the outer edge of the earths atmosphere when the earth is at its average distance from the sun is called the solar constant. The intensity of energy actually available at the earths surface is less than the solar constant because of the absorption and scattering of radiant energy as photons inte ...

- Wind Power - 1,040 words
Wind Power Energy is the ability to do work. It surrounds us in all aspect of life. However, the ability to harness it and use it, as economically as possible, is the challenge before mankind. Alternative energy refers to energy sources, which are not based on the burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution both from burning fossil fuels and nuclear waste by products. Fortunately, there are many means of harnessing energy that have less damaging impacts on the environment. One example wind power. Wind energy is a clean and renewable source of electric power and is also the world's fastest growi ...

- Wind Power - 2,254 words
Wind Power annon The wind turbine, also called a windmill, is a means of harnessing the kinetic energy of the wind and converting it into electrical energy. This is accomplished by turning blades called aerofoils, which drive a shaft, which drive a motor (turbine) and ar e connected to a generator. 'It is estimated that the total power capacity of winds surrounding the earth is 1 x 1011 Gigawatts' (Cheremisinoff 6). The total energy of the winds fluctuates from year to year. Windmill expert Richard Hills said that the wind really is a fickle source of power, with wind speeds to low or inconsistent for the windmill to be of practical use. However, that hasn't stopped windmill engineers from t ...

... d A is the area. The number of blades on a windmill varies. There are many different types of windmills. The following equation helps figure out how fast the a certain-bladed windmill will rotate in relation to windmills with different numbers of blades: Speed of windmill="1" / sq. root of number of blades The aerofoils of a four bladed machine rotate 71% as fast as that of a 2 bladed machine. A six bladed machine rotates at 58% and an 8 bladed machine rotates at 56% as fast as a 2 bladed machine. Electricity and Storage of Energy As mentioned previously, the generators in a wind turbine can convert the mechanical energy produced by the rotation of the shaft into electrical energy, DC. F ...
