Supplies Energy To Electric Generators
2,717 wordsPresentation Dialogue SOLAR ENERGY. All life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary for plants and animals to survive. The heat from the sun causes water on the Earth's surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature o...

Electricity In A Geothermal Power Plant
1,220 wordsEnergy is the ability to do work. The two different types of energy are kinetic and potential. Kinetic energy is energy in motion and potential energy is energy that is stored. Energy is measured in units which are BTU (British thermal unit) and a joule. The Law of Conservation of Energy states that energy can't be created or destroyed, but it can be changed in form. Heat is a form of energy that comes in different forms such as conduction, convection, and radiation. Conduction is when energy is...

High Emf Fields
415 wordsHomes are filled with electric magnetic fields (EMFs), EMFs are created every time anything electrical is used. Hair dryers, alarm clocks, micro waves and radios are just a few examples. All these appliances cause leukemia, a form of cancer. High EMF fields are not very unusual. EMFs can pass through walls, so one can also be exposed to them from power lines and transformers. Using a hair dryer for 3 minutes would give the same exposure that one would get living next to a high voltage power line...

Use Tin
582 wordsTinTin's discoverer is unknown but one thing is known. Tin has been used and discovered by the ancients. Tin was an accidental discovery. Tin has been around for many years. Proof is in the fact that tin is mentioned in the old testament of the bible. Tin had a great effect on the world because of its low price, high electric conductivity, and because tin protects against rust and weak acids in food if the can is made out of tin instead of aluminum. Some common compounds of tin are org antin a c...

Use Of Water Energy
1,301 wordsHYDROELECTRIC POWER The idea of electricity started around 500 B.C. as the Greek philosopher Thales experimented with amber, a fossilized tree sap, by rubbing it and observing that it starts to attract certain types of materials, this is the first documented study of static electricity. In 1646 the term electricity was coined by Walter Charlton to describe the attraction of the different materials. Throughout the 1700's many advancements in the study of electricity were made to include the idea ...

Most Important Scientific Discoveries
945 wordsThe Application of Science to Engineering Improvements in engineering are very important to the industrialization and prosperity of a country. Although engineering improvements sometimes come through trial and error they are most often achieved by applying pure science and mathematics to engineering. Canadian engineering was improved a great deal in this manner. The engineering associated with building materials and long distance communication, two of Canada's most important industries, was impr...

Use Of Superconductors By The Armed Forces
969 wordsI am writing to inform you of a recent economic opportunity that could leave you rich if you choose to invest. The prospect of wealth relies on superconductors- the system of the future and present. You could earn millions by contributing to the research of superconductors. Superconductors consist of an element, inter-metallic alloy, or compound that will conduct electricity without resistance (loss of energy flowing through the material) below a certain temperature. Once in motion, electrical c...

Use Of Modern Electric Conveniences
563 wordsCooperative Pursuit Rural electric cooperatives are formed in order to bring rural areas of the United States fast, affordable, and efficient electricity. An electric co- op is designed to offer you electricity at a cheaper rate and enables one to make use of modern electric conveniences. Conveniences that an electric co-op bring include hot water, lights, and heat. Imagine how life would be with these electric conveniences at your disposal. Life as it is known would be completely different; mor...

Use Of Energy In The Home
6,014 wordsIn the last thirty years, America has witnessed an environmental revolution. New laws like the 1963 Clean Air Act and the 1974 Safe Drinking Water Act forged new ground in political environmentalism. Social phenomena like Earth Day, organized by Dennis Hayes in 1970, and the beginning of large-scale recycling, marked by Oregon's 1972 Bottle Bill, have help change the way Americans think about the environment. As we approach the third millennium, however, we must reconsider our place on the plane...

Current Passes Through The Coil
760 wordsLoudspeakers - Consist of a circular permanent magnet surrounding a freely moving coil. The coil is attached to a cone-shaped, flexible diaphragm or speaker cone. - When current passes through the coil, magnetic forces act on the coil, causing it to move in or out depending on the direction of the current. - If AC current passes through the coil, it will move alternatively in and out as the current changes direction. The coil will therefore vibrate at the same frequency as AC current. Society ha...
