...SOLAR PARABOLIC TROUGH 1.0 System Description Parabolic trough technology is currently the most proven solar thermal electric technology. This is primarily due to nine large commercial-scale solar power plants, the first of which has been operating in the California Mojave Desert since 1984. These plants, which continue to operate on a daily basis, range in size from 14 to 80 MW and represent a total of 354 MW of installed electric generating capacity. Large fields of parabolic trough collectors supply the thermal energy used to produce steam for a Rankine steam turbine/generator cycle. Figure 1. Solar/Rankine parabolic trough system schematic [1]. Plant Overview Figure 1 shows a process flow diagram that is representative of the majority of parabolic trough solar power plants in operation today. The collector field consists of a large field of single-axis tracking parabolic trough solar collectors. The solar field is modular in nature and is composed of many parallel rows of solar collectors aligned on a north-south horizontal axis. Each solar collector has a linear parabolic-shaped reflector that focuses the sun’s direct beam radiation on a linear receiver located at the focus of the parabola. The collectors track the sun from east to west during the day to ensure that the sun is continuously focused on the linear receiver. A heat transfer fluid (HTF) is heated as it circulates through the receiver and returns to a series of heat exchangers in the power block where the...

...Communication, Homeostasis & Energy Communication & Homeostasis Outline the need for communication systems within multicellular organisms, with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli, e.g. temperature, oxygen concentration and levels of sunlight. These may be over time, e.g. winter fur to summer fur, or quickly, e.g. changing size of pupils. Internal environments change too- the build up of carbon dioxide as a result of respiration changes the pH of the tissue fluid, and therefore inhibits enzyme activity. Multicellular organisms need to coordinate different organs, so this requires a good communication system which will: • Cover the whole body • Enable cells to communicate with each other • Enable specific communication • Enable rapid communication • Enable both short and long-term responses. State that cells need to communicate with each other by a process called cell signalling. State that neuronal and hormonal systems are examples of cell signalling. Define the terms negative feedback, positive feedback and homeostasis. Negative feedback- A process in which any change in a parameter brings about the reversal of that change so that the parameter is kept fairly constant. Positive feedback- A process in which any change in a parameter brings about an increase in that change Homeostasis- The maintenance of a constant...

...excessively complex system of chain reactions engineered to complete a relatively simple task. The primary aim of the task was to design and construct such a device which functioned to successfully trigger a party popper after exactly sixty seconds of operation, including a range of energy transfers between components of the device. | Outline of Process and Planning stage | Initially, individual components of the device were designed separately. Team members brainstormed and integrated ideas for components. Sketches were created and discussions were held regarding the proposed function of the components and the overall device. | Outline of initial design stage and prototype testing | Following development of these designs, some components were constructed and tested both individually and in combination with other components. Early prototypes of these components included the use of pendulums, pulleys and marbles on ramps. | Outline of evolution of the device and modifications | After testing of prototypes, the device was modified to improve efficiency and overall functionality. Some components were removed and replaced by more efficient processes, such as the swapping of the 'Marble Roll Device' for a 'Magnetic Device'. In order to meet the time criterion and to include a sufficient number of energy transfers, additional components were added during early testing of the prototype device, such as the inclusion of dominos and a spiral ramp. | Outline of construction and testing...

...the definition of open systems and the outline of internal, competitive, and macro environments of an organization. The contemporary approaches to management are sociotechnical system theory, quantitative management, organizational behavior, and systems theory. Sociotechnical system theory is a theory of management that believes technology merely constrains human action instead of rigidly determining behavioral outcomes. This can build good human relations into the technology workflow. Quantitative management relies on solely technology. The quantitative management approach involves the use of math modeling to find the right solutions to problems. Applied to workplace challenges, going from making decisions during product development to fix employee conflicts. Organizational behavior is like sociotechnical system theory when the focus is on people rather than technology. Organizational behavior is the study and knowledge of how people act in organizations. The goal is to build better relationships by achieving human objectives, organizational objectives, and social objectives. Similar the system theory does not look at individuals but the flow of business as a whole. It focuses on subdivisions within the organization and how it ties in with the big picture, the business. An open system is a system that interacts with its environment by exchanging energy, materials, information with an aim of system renewal and growth. A feature of an open system is negative entropy where...

...article is about how US can be converted to 100 percent renewable energy country. I chose these particular articles because of what I truly take away from the course. Through this course, I learned the value of chemistry to our environment. Chemistry has a tremendous importance and contribution to our environment. In the class, we have discussed the issue of pollution in the world we live today. The two articles articulate how we can save and benefit the environment through the combination of chemistry and modern technology. By continuing to be innovative, scientists are achieving tremendous steps toward creating clean environmental friendly energy. By being aware of these important achievements, we all can do something about to help the environment. Summary of Article #1 Storing energy can make renewables more reliable, but current technologies such as lithium-ion batteries are limited by safety issues, high costs and other factors. The researchers combined, for the first time, two separate microbial energy systems: one that uses bacteria to form acetate from electricity and one to convert the produced acetate back into electricity. The researchers successfully charged the battery over a 16-hour period and discharged it over the next 8 hours, mimicking the day-night pattern typical for solar energy production. They repeated this cycle 15 times in as many days. With further optimization, they say the energy density of the microbial battery could be competitive with conventional...

...Moroccan Agency for Solar Energy The purpose of this plan is to outline the products and services offered by the Moroccan Agency for Solar Energy and how they could benefit geographical areas that are almost entirely reliable on non-renewable energy. EXECUTIVE SUMMARY Solar energy is becoming an increasingly relied on resource, and in some countries, the only source of energy. Morocco has launched what is to be considered one of the largest solar energy projects in the world. Responsible for implementing the solar plan is The Moroccan Agency for Solar Energy (MASEN). At a geographical advantage resulting in one of the highest rates of solar insolation in Morocco, MASEN is projected to provide up to 18% of the nation’s annual electricity generation. It’s clear that Morocco is luckier than countries that are tied to darkness for the better part of the year, as well as smaller countries (i.e. islands) without the land space to set up solar energy plants. Solar power stations, or solar farms, are large scale photovoltaic and concentrated solar power systems. Photovoltaic systems use a different technology than concentrated solar power systems, so the two are not to be confused, however, some solar farms are known to use a combination of both technologies. The difference is photovoltaic converts light directly to electricity, whereas concentrated solar power systems use heat to drive conventional generator systems. Initial setup costs for solar farms are steep, the...
