Algal Bio-Diesel Power Plant Essay Example for Free

Algal Bio-Diesel Power Plant Essay Algae- most promising alternative renewable energy source available. It decreases the need for fossil fuels and thus makes our environment healthier. Algae oil is produced as much faster as 30 times than other biomass feedstock while its producing amount is up to 300 times more resulting 600 tons of bio-diesel per day which will produce 200MW of electricity per hour. MAJOR COMPONENTS IN ALGAE BIO-DIESEL POWER PLANT: 1. Algae plantation 2. Algae oil extraction and bio-diesel plant 3. Internal combustion power plant Continuous Algae production utilizing the photobioreactors is a highly reliable method for producing high density monocultures of marine and fresh water algae. The total control of all parameters are automatically controlled via a PLC, making the device dramatically reduce the labor requirements and eliminates handling problems. The photobioreactors work by recirculating algae, nutrients, water and CO2 through transparent tubes to maximize the amount of light reaching the algal cells, the short light field maximizes this process; thereby enhancing the photosynthesis process. There are two major types of extraction namely * Mechanical extraction * Chemical Extraction The chemical extraction methods for algae extraction is done mainly using Chemical Solvents such as Benzene, Hexane. Other chemical methods include soxhlet extraction and supercritical fluid extraction. The mechanical extraction methods include the Ultrasonic Extraction. Internal combustion engines are constructed from one or more cylinders, each sealed at one end and open at the other, in which close fitting pistons can move up and down. The engine derives its power from the burning of a compressed air-fuel mixture in each of the cylinders in succession. The fuel is ignited when the piston is at the top of its stroke and the expansion of the burning gas drives the piston downwards. The reciprocating motion of the pistons is converted to rotary movement by a crankshaft which delivers motive power to the desired application, in this case a generator. Air or an air-fuel mixture is introduced into the cylinder when the piston is at its lowest point and a flywheel on the crankshaft provides the momentum to drive the piston upwards to compress it. The piston and connecting rod in a reciprocating engine form a large mass which is accelerated from zero to a very high speed and decelerated back to zero again with every revolution of the engine (100 times per second in an engine operating at 6000 rpm). This places immense forces on the moving parts of the engine. CONCLUSION: Therefore, based on the comparisons made over other power plants and the advantages of the algal biodiesel power plant, we conclude that algal biodiesel is one of the most promising green fuel because of its potential as a renewable and sustainable fuel source for the electric power generation.

Legalization of Marijuana :: Argumentative, Marijuana Legalization

The legalization of marijuana has been questionable for many many years now, but the government just seems to always decline. I feel that marijuana should be legalized. There are many reasons for and against legalization, but the arguments for it outweigh the arguments against it. I believe marijuana should be legalized for three main reasons. Legalization will bring in much needed tax dollars, it will free up prisons and their resources, and it will save the U.S tons of money. If marijuana is legalized, it can be taxed by the federal government, like alcohol and cigarettes are now. If this is done, not only will the government save millions of dollars on searching for marijuana, the government will make billions of dollars off the sale of marijuana which can be used for drug education programs to help educate the youth of America. In the United States, all levels of government (federal, state, and local authorities) participate in the "War on Drugs." We currently spend billions of dollars every year to chase peaceful people who happen to like to get high. These people get locked up in prison and the taxpayers have to foot the bill. We have to pay for food, housing, health care, attorney fees, court costs, and other expenses to lock these people up. This is extremely expensive! If you must know, it costs taxpayers like you and me $42,000 a year to keep just one criminal in jail. That's more than twice the amount citizens spend on sending their children to school. Taxpayers only spend a dissapointing $13,000 a year for public schooling. We could save billions of dollars every year as a nation if we stop wasting money locking people up for having marijuana. In addition, if marijuana were legal, the government would be able to collect taxes on it, and would have a lot more money to pay for effective drug education programs and other important causes. According to The Report of the Task Force on Cannabis Regulation to the Center for the Study of Drug Policy, "marijuana is one of the largest tax-exempt industries in the country today." 10-15 billion dollars a year could be made simply by legalizing cannabis. Hemp, the nonpsychoactive version of the plant, has many, many uses but is outlawed by the U.S. government. Hemp is an incredibly strong fiber that can be used for ropes, clothes and

Hum/114 Wk 1 Individual – Drill or Not to Drill

To Drill or Not to Drill HUM/114 October 25, 2010 To drill or not to drill is large debate that many Americans are not sure how to answer. Many people are upset about the recent oil spill in the Gulf of Mexico and have been discussing that we could invest in alternative sources of energy more, but without knowing the facts. Unfortunately, misfortunes like this happen all of the time, it is a part of life and all we can do is discover from our mistakes and move forward. One of the main complaints is that â€Å"Offshore drilling poses environmental risks. Yes the environmental danger of off shore drilling gradually has affected our wild lives and fish stocks. Researchers argue that this is not just a short-term effect because the remaining species can obtain new diseases and not be able to fight them because of lower heterozygosity index. In addition they are afraid that it will lead to the extinction of a variety of species. Due to today’s new technology that is continuously u pdated the new drilling rigs have considerably reduced the risk of potential accidents.In the most recent situations that have occurred due to oil rigs BP being one and the Exxon Valdez accident in 1989 off the coast of Alaska being another. Researchers were able to discover that there were several factors that stacked up in order for these accidents to occur. Once of the main causes involved highly negligent practices such as strained workers, unfulfilled promises of advanced technology equipment and several safety regulation violations.BP has been known to have an appalling track record concerning safety and has been fined 760 times in comparison to one of our leading oil drilling companies ExxonMobil, who has been only fined once and has had no incidents. Another argument is how long can we honestly rely on oil? In the long run researchers are saying that our dependence on oil must end entirely. This is most likely a true statement; however, it is reality that even with scrupulou s development of these energy resources they are far from eing able to produce the energy needed in today’s world. I strongly support renewable energy, but researchers are a long way away from being able to convince us that it is possible much less feasible. As we stand the reality of the matter is that we do need additional energy and while scientist are in the process of getting all of the resources together, offshore drilling is a very sensible and practical way of obtaining energy.I do realize that oil is not sustainable but believe until it is diminished we should continue using it in the most efficient way possible.

Rhetorical Analysis Of Aristotle s Theory Of Rhetoric

Rhetoric can best be explained as how a speaker uses persuasion to influence their intended audience. Rhetoric is usually seen as a power that we as communicators are using to obtain the belief of others. Almost everyone uses rhetoric throughout their everyday lives without even knowing. We are constantly communicating with one another trying to prove some sort of point. There are many different figures that played a huge role in establishing rhetoric, but Aristotle is seen by many as the father of rhetoric. Not only does Aristotle have an influence on people of present day, but he had an influence on other Greek philosophers such as Cicero and Quintilian. His works established a baseline of rhetoric that many people after his time took and ran with. If he were around today, Aristotle would be seen by many as a rhetorical leader who could possibly end many communication differences and problems that are present in today’s society. Aristotle was born in Stagira, Greece in the y ear 384 B.C. His father, Nicomachus, who died when Aristotle was a young boy, was a special court physician to the king of Macedonia (Biography, â€Å"Aristotle†). This lead Aristotle to be greatly influenced by the court of Macedonia. When he turned 17, Aristotle set out for Athens to pursue an education at Plato’s Academy, which was a top of the line institute in Greece at the time. Once Aristotle graduated from the institute, and Plato died in 347 B.C., he was given the opportunity to be the headShow MoreRelatedWhat Are They Key Factors for Success in Debating; Team Processes and Preparation, or the Public Speaking Skills Employed1404 Words   |  6 Pagesquestion and ground your analysis in communication theory.
