Effects of Using Bio Diesel as a Main Fuel Source The cost of fuel is an increasing problem and the cost of obtaining crude oil to process into many kinds of fuels has risen. By replacing diesel fuel with an alternative such as bio diesel, we can lower the cost of fuel. Although using this fuel has a few draw backs, they are overcome by the beneficial effects. A few of the effects of using this fuel as a main source are lower prices, higher availability, and climate adaptability. Bio-diesel is a relatively easy to produce, and low cost fuel.
Moreover, near zero surface tension as well as low viscosities similar to gases, allow supercritical fluids to easily penetrate a microporous matrix material to extract desired compounds. The synergistic combination of density, viscosity, surface tension, diffusivity, and pressure and temperature dependence, allow supercritical fluids to have exceptional extraction capabilities. Many corporations utilize supercritical carbon dioxide to saturate the polymer with solvent (CO2). Upon depressurization and heating the CO2rapidly expands, causing voids within the polymer matrix, i.e., creating a foam. Carbon dioxide is by far the most commonly used
When making connections it is so much easier to splice the copper cable than it would be for the fiber. Copper cables are also very flexible; you can have your wire go wherever without cracking or breaking. As for the disadvantages, all the advantages of the fiber are the downfall of the copper cabling. People want faster, better, farther. So, over time, we will lose the copper cables and move onto the
However the use of an inert gas makes this type of welding less portable than arc welding which requires no external source of shielding gas. During the welding process, we are observed and analyze the performance of each types of welding in this experiment. Technician start welding process with Metal Active Gas welding (MAG). This welding use 1.2mm copper coated filler wire and mixture of shielded gas contain 80% of argon plus 20% of carbon dioxide. The coating of copper filler wire is to improve arc performance and to protect it from rusty.
Copper wiring is flexible when installing so incase a technician has to bend it around a wall or at a certain angle to reach it to an end point, the cable can handle it. Also equipment to support copper wiring is relatively inexpensive to run. The weaknesses to copper wiring would be that it is susceptible to electromagnetic inference (EMI) from outside forces and also has a higher rate of corrosion over time by oxidation. Fiber optic cabling is a more expensive option for communications. Fiber optic cabling is immune to EMI and other noise interferences and therefore the chance of signal loss is greatly reduced.
Carbon is an element, and oil naturally has lots of them. While plastic has many benefits, one frequently cited problem with this useful material is that it’s usually not biodegradable, not able to naturally decompose and so if it’s thrown away instead of recycled, it can create a lot of waste. To help with
The bulbs create less heat during use, which can lead to lower cooling costs and its green friendly, decreases amount of energy used by 5%. Laser Transmitter Laser transmitter have a much smaller and tighter light input and can be easily coupled to single mode fibers, this makes the laser transmitter perfect for longer distances and high speed links. Laser has a high bandwidth capability some are used up to 10GHz or 10Gbps this makes Laser transmitters more expensive. Laser Transmitters have a narrow spectral output that suffers very little chromatic dispersion. Laser Transmitters avoid interference because the frequencies between the lasers have narrow beams that are less likely to have significant side lobes that could introduce interference.
Gas tungsten arc welding (GTAW), also known by many people as tungsten inert gas (TIG) welding, an arc welding process that uses a non-consumable tungsten electrode to produce the weld. GTAW is mostly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. Many people think GTAW is easy to do, but it is more complex and difficult to master, so that it is significantly slower than most other welding techniques. In the year 1800 Humphry Davy discovered the electric arc. While the arc welding developed slowly.
Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation. They also have an unlimited supply as they are renewable unlike fossil fuels. Even more importantly, renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so has minimal impact on the environment. Renewable energy projects can also bring economic benefits to many regional areas, as most projects are located away from large urban centres and suburbs of the capital cities.
Fossil fuels are notorious for producing large amounts of carbon dioxide and other gases that are harmful to humans and the environment. This harmful effect constitutes a need for renewable sources of energy. Sources of renewable energy, such as wind energy have a “Low life cycle carbon footprint, and break even in eight months” (1) Often, the only carbon dioxide produced by renewable energy is that required in the making of the materials. A renewable resource quickly compensates for the carbon produced in production by producing electricity that other polluting sources would have produced. (2) Renewable energy is simply better for the environment then non-renewable energy, according to the Union of concerned scientists, the statistics show that “The comparison becomes clear when you look at the numbers.
