Energy Resources
In the “Alternative energy” video they describe a few different forms of renewable energy that compete with fossil fuels. Among those present in this video were wind power, solar energy, and biomass fermentation. Although, each one of these energy sources provides efficient energy with extensive harm to the environment form by products they each posses their own challenges while using and managing them.
Energy from wind generators obviously depends on strong enough wind to move the large turbines. In return, the spinning turbines create energy. When there is not enough wind to spin the turbines energy cannot be created through this method. However wind generators are currently being used in the United States and Europe, and it is proving to be an efficient method to create electricity. Another source mentioned in the video is solar power. Solar power is generated when solar panels collect sun light beams which turn gears in a generator providing energy. As far as solar panels go, the challenge with using them as an alternate means of energy is that they are very expensive to purchase and maintain. Another, challenge with using solar panels as a means of renewable energy is the intensity of the sunlight affects the output of energy. If the solar panels are not receiving enough sunlight, they will not produce enough energy for use.
The next energy source that was talked about in the video was biomass fermentation as a means of energy. Some of the challenges with using biomass fermentation as a means of energy are getting farmers to collect the materials after harvesting to convert it into fuel. Ethanol fuel is basically made out of the material that is made from the harvested farmer’s fields such as corn. But, according to the video scientists are experimenting with other

Ferro Case Study Answer

...Garima Sharma has quite some experience in terms of handling relationships : she was the head of human resources at Norton Network for 10 years before joining Ferro, and has been entrusted by her husband to organize Metal Star's representative, Sheikh Yusuf's trip to India to inspect the product he coveted. We believe her decision to release the shipment was a wise one for many reasons. First of all, 45% of Ferro's revenues come from foreign operations, 5 of the top 10 Ferro's clients are foreign, and although Metal Star isn't one of them, it cannot be ignored as the company had agreed to buy 6 machines for 10 million INR. Plus, with both the domestic and foreign competition that can offer pretty much the same high-quality machines at lower prices, Ferro needs every deal they can strike in order to manage to get the company through with its investment plan and get up to speed in terms of cutting-edge technology. In a nutshell, Ferro needs to find a solution which satisfies both parties. Garima is known to have a good and quick understanding of people's traits, which makes her able to offer customized treatments to her clients, even during turmoiled times (i.e payment crisis with Sheikh Yusuf). And this is exactly what she has done by finally agreeing to split the demurrages between Ferro and Metal Star before eventually releasing the machines to Yusuf, in hope of receiving payment. I don't think there would have been any better solution, as some other ways have already...

Heat

...Running head: HEAT 1 Heat Adrienne Branch Professor Olivia Uitto Science 110- Introduction to Physical Science April 27, 2012 HEAT 2 How does the study of heat relate to the kinetic theory of matter? The philosophers Democritus and Lucretius stated that matter is composed of particles. They also believed that these particles were in constant motion and in the state of solid, liquid, or gas (Gibbs, 2010). They called this theory the Kinetic Theory of Matter after the word kinema, which is Greek (Gibbs, 2010). In the study of heat we learn that whenever heat is added to a substance, molecules and atoms vibrate faster. Due to the quickly vibrating atoms, the area between the atoms get larger (“Atoms and Molecules”, n.d.). The state of the matter of the particular substance is determined by the motion and space between the particles. The more an object expands, the more space it takes up (“Atoms and Molecules”, n.d.). During this process, the mass of the particular object will not change. Solids, liquids, and gas all expand when heat is added. When an object cools, molecules vibrate at a slower pace. The atoms start moving closer together again and the matter begins to contract. During this process as well, the mass will remain the same (“Atoms and Molecules”, n.d.). Several good examples of the Kinetic Theory of Matter relating to heat is with sidewalks and railroad tracks which are solids. They expand...

Discussion Questions

...Lithonia, GA Campus Physical Sience - Professor Freeman July 19, 2012 Discuss how energy can be converted from one form to another, giving specific examples. Today there are many different forms of energy and they all have the ability to transform produce change and to do work. How energy is converted from to another is based on the law of conservation of energy. “The law of conservation of energy is that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another including transformation into or from mass, as matter.” Examples of energy are those that follow: Mechanical energy stored or moving energy also referred to as potential or kinetic energy, electrical energy the movement of electrons, thermal energy heat of an object, and radiant energy light and warmth of the sun are all energies that can be converted to another form of energy. For example, the chemical energy stored in the muscles of our legs is converted to kinetic energy or mechanical energy when we pedal, a toaster oven plugged into an electrical socket takes electrical energy and converts it to heat/thermal energy, and radiant energy converted to heat energy provided by the sun that heats earth. Define what we mean by fossil fuels and explain why there are attractive sources of energy. Fossil fuels are also natural resources of energy that is a product of millions of years of decomposed plant and animal pressured by heat trapped underground...

Unifying Manifesto

...PREFACE Adam Jefferson, a divine manifest of Adam Smith's materialism and Thomas Jefferson's idealism, is our troubled modern day hero. He awoke in the middle of his life - broke and lost. A serial entrepreneur, his life was a never-ending quest for material success. At age 38, as Joseph Campbell forewarned humanity, Adam had "climbed the ladder of success, only to realize it was propped up against the wrong wall." Alone, with nothing else to lose, Adam Jefferson climbed down off of the ladder and searched for the wall of his future. This led him on a 100-day odyssey to start the ascent of his new life, an epic journey which called him across the world discussing today's challenges and opportunities with the great minds of our past - Carl Jung, Mary Parker-Follett, Martin Luther King, Jr., Mohandas Gandhi, Albert Einstein, and many others. An act of their collective genius and magical combustion, a psychological and sociological theory for sustainability and success was formed. Like all heroic quests, Adam ended where he had begun. Prior to his expedition, Adam had an unforgettable encounter with one of the great minds of the 20th century. One freezing, early morning on January 17, 2009, Adam Jefferson met the famed Harvard psychologist Lawrence Kohlberg in Cambridge, Massachusetts. They walked the beach in Winthrop for hours, discussing morality and the questions one ponders in the solitude of despair. They exchange woes - "You tell me yours, and I will tell you mine."...

Ocean Energy

...types of energy: thermal energy from the sun's heat, andmechanical energy from the tides and waves. Oceans cover more than 70% of Earth's surface, making them the world's largest solar collectors. The sun's heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world. Workers install equipment for an ocean thermal energy conversion experiment in 1994 at Hawaii's Natural Energy Laboratory. Credit: A. Resnick, Makai Ocean Engineering, Inc. Ocean thermal energy is used for many applications, including electricity generation. There are three types of electricity conversion systems: closed-cycle, open-cycle, and hybrid. Closed-cycle systems use the ocean's warm surface water to vaporize a working fluid, which has a low-boiling point, such as ammonia. The vapor expands and turns a turbine. The turbine then activates a generator to produce electricity. Open-cycle systems actually boil the seawater by operating at low pressures. This produces steam that passes through a turbine/generator. And hybrid systems combine both closed-cycle and open-cycle systems. Ocean mechanical energy is quite different from ocean thermal energy. Even though the sun affects all ocean activity, tides are driven primarily by the gravitational pull of the moon, and waves are driven primarily by the winds. As a result, tides and waves are intermittent sources of energy, while...

Beaver Log

...on the bomb fire and burned which caused physical and chemical reactions and changes. Let’s talk about some of the physical and chemical properties. Physical properties can be observed or measured without changing the composition of the matter. The beaver’s log had the following physical properties. It was shaped like a cylinder with pointed ends, brown and rough. The beaver ate the bark and the soft tissue in order to receive nourishment. Chemical properties of matter describe its “potential” to undergo some chemical change or reaction by virtue of its composition. As the beaver log burns, it goes through three phases. The first phase is the evaporation of water. As the wood is heated moisture evaporates quickly consuming heat energy in the process. The second phase is the emission of smoke. As the wood heats up, it starts to smoke. The smoke is the visible result of the destruction of the solid wood as it vaporizes into a cloud of combustible gases. The smoke will burn if the temperature is high enough and oxygen is present. The third and final phase is the charcoal phase. As the fire grows and most of the gasses have vaporized out of the wood, charcoal remains. All three phases of wood burning occur at the same time. The wood gases can be flaming and the edges of the pieces can be glowing red as charcoal burns, while moisture in the core of the wood is evaporating. The wood went through both a physical and chemical change. A chemical change can produce heat...

Energy

...down, charm, strange, top, or bottom. What can quarks be broken down to? Theoretical matter aka empty space. How do these things work? Energy, pure energy. When you break it down everything comes down to either empty space or energy. How do you control energy? You control energy with energy. There are several types of energy, but let’s start with the most basic. Good and bad. Good energy is when the energy you are using or the energy that is around is being used or put to a good purpose. Bad energy happens when the intent is to harm or negatively affect someone or something. You also have physical and mental energy. Physical energy is when you affect something outside of yourself, mental energy is what happens inside your own mind. There is potential for mental energy to become physical energy (like when your brain sends signals to muscles to move you) but one thing at a time. First let’s focus on bad energy. Define “bad”. Well: “bad-adjective-having undesirable or negative qualities.” Any type of energy can be “bad energy”. We all create bad energy every day. If we are angry at someone or angry at ourselves, that’s bad energy. If you hurt someone or yourself, that’s bad energy. Even if you are sad or upset that’s bad energy too. It all has an effect on our overall being. You can affect physical things with your bad energy by using mental energy that has been...

Marketing

...Before managers can begin to formulate an effective strategy, they must make a critical examination of the firm’s environment. Assessing the strategic situation is the first phase in determining the content of the proper strategies for a firm. This process begins with an assessment of the general environment of the firm, in terms of economic, technological, social, and political/legal influences. Analyzing the organization's industry is the second major aspect of assessing the firm's strategic situation. An industry structure analysis identifies the major forces affecting competition in an industry and determines the strengths and weaknesses of the business relative to the industry. Michael Porter has identified five basic competitive industry forces: the threat of new entrants in the industry, the intensity of rivalry among existing competitors, the pressure from producers of substitute products or services, the bargaining power of buyers of the industry's outputs, and the bargaining power of suppliers to the industry's companies. Management must find for a firm a position in the industry from which it can best defend itself against these competitive forces or can influence them to its advantages. Another major element of the industry environment is the product/market life cycle which assumes that all products, and, therefore, industries, move through stages of a life cycle. In analyzing an industry, its is also useful to determine if the industry is a global industry...
