Wind Turbine – Research Paper

In his article “Move Over, Oil, There’s Money In Texas Wind,” Clifford Krauss writes about the growing popularity of wind turbines in Texas. It is an alternative source of energy, and many Texans are turning oil fields into wind farms. If the rate of wind turbines as a use of electrical generation keeps growing, wind power can become the main source of electricity in Texas and eventually the United States. Some drawbacks to wind power and turbines are that they are more expensive than fossil fuels, and on the hottest days, when it is need it the most, it is rarely windy. These turbines are increasing in size, and they are getting deadlier to bats and birds as the size of their blades increase. Despite the drawbacks to wind turbines, they are more environmentally friendly, and wind is also a renewable resource. Wind power is not only confined to Texas. Iowa, Minnesota, Colorado and Oregon have also started using wind turbines as a source of power. Long Island is also on the same track. Other countries have also caught on to wind power, such as Germany and Spain.

What are Rainforests?

I’m going to talk about is the rainforest. The rainforest is a very humid and wet biome. With a estimated rainfall of 50-260in a year, most of it comes from its own evaporation from its trees. The average temperature year around is 77 degrees Fahrenheit Rainforests at one covered 14% of the world but do to deforestation and the lack to replant the trees it has been depleted to 6%. Not just the trees are being cut down experts say we are losing close to 140 plant, animal and insect species every day. Removing one plant in this fragile ecosystem could seriously harm it all, most of the plants and animals are dependent on a certain plant. The rainforest is home to many animals and plants. Its home to more then half of the worlds plants and trees and animals. There are rainforest located in Brazil, Congo (Democratic Republic), Peru, Indonesia, Colombia, Papua New Guinea, Venezuela, Bolivia, Mexico and Suriname. There are four layers to the rainforest the emergent layer, canopy, understory, and the floor.

Tampa Bay Seawater Desalination Plant

Desalination is the process of removing salt from water making it suitable for drinking. Distillation, electro dialysis, freezing and reverse osmosis are all methods of desalination. (“Water, desalination of, 2006) In the distillation method, saltwater is heated and the water evaporates leaving the salt behind. Due to fuel cost of turning water into vapor other distillation methods were developed. The multi-stage flash distillation method is conducted by either applying a vacuum to reduce the boiling temperature or exposing a thin film of water to high heat causing flash evaporation. Plants using this method account for 85% of all desalinated water in the world. (“Multi-stage flash distillation”, 2010) In electro dialysis salt is dissolved in water splitting up the salt into ions. The ions are then filtered by membranes and allow desalinated water to be tapped. This process uses a great amount of energy and is impractical. The most promising approach is the reverse osmosis process, which applies pressure to saltwater to force it through a special membrane that only allows pure water to pass.

Impact of Technology on the Environment

Ever since the beginning of time, humans have tried to adapt to their environment. Controlling nature is an almost impossible task to perform, so humans began relying on technology to achieve their goals. Technology can maintain the well-being of humans, but at the same time, have negative side effects. Humans who created technology may end up being controlled by it. Sandra Steingraber, an ecologist, discusses the negative effects of petrochemicals on humans in her essay, “War”. Her essay also discusses how the period of war led to the country having a war mindset. Gregory Stock, a scientist who researches the potential of genetics, discusses the use of germinal choice technology to better the future generations, in his essay, “The Enhanced, and the Unenhanced”. Stock also mentions that GCT is inevitable and that we must prepare for it. David Abram, an anthropologist, discusses the role of magicians and how they are important for connecting humans with their surroundings. Abrams idea of a magician is not the same as the one understood in Western culture, in which the magician performs tricks and illusions. He says that a magician plays an important role in the ecological function by connecting the human world and the “more-than-human” world that we live in. Abram’s essay, “The Ecology of Magic”, focuses on the definition of magic and that every living, and non-living, thing in the world is a form that can experience interactions with other forms. These three authors seem to talk about totally different topics, but they share one point. An over dependence on technology has lead to a negative impact on the relationship between humans and the environment.

Cloning: Designer Babies

First let me define “designer babies”. The Oxford English Dictionary defines this as “a baby whose genetic makeup has been artificially selected by genetic engineering combined with in vitro fertilization to ensure the presence or absence of particular genes or characteristics” (Soanes, C., and A. Stevenson). The research has been going on for a long time. It started back in 1976 when the first successful genetic manipulation took place on mice, in efforts to produce more accurate disease models and test subjects (web.mit.edu). At the present time it is illegal to create “designer babies” so it’s not something we will be dealing with tomorrow. Let me get back to what a “designer baby” means but in layman’s terms. It means you can choose what kind of features your child has before they are born. This is because of genetic screening. A good thing about genetic screening is that it has made it possible to eliminate genes associated with several genetic defects and terminal illnesses, but it has also made it possible (in the future, not now) for parents and doctors to genetically screen embryos to be able to give that child characteristics of their choosing. How would “designer babies” be made? This question is answered in the beginning of this paragraph, but to put it in simpler terms, an embryo is created by in vitro fertilization, a single cell is removed from that embryo, the cell is genetically tested, and then the parents decide whether to implant the embryo in the mother’s womb or dispose of it (www.bionetonline.org).

Solar Cells

Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products.

Alternative Energy Research Paper

The world’s sources of fossil fuels are drying up faster than the earth can renew them. Fossil fuels, like coal and oil take the earth thousands of years to reproduce so an effective alternate energy source must be explored. For many years we have been running out of oil. This phenomenon is called the Hubbert peak theory also known as peak oil. Hydrogen is a great option to power an engine. To make hydrogen we can decomposition methane or using electrolysis. There are two methods: combustion, and fuel cell conversion. Nuclear power is also an option to powering a vehicle. As we all know we have to use uranium to produce nuclear power. Biofuel is a fuel that comes from biomass, living organisms, like cow manure. This area is very active, because it can convert biofuels and other fuels into fuel cells (Biofuels)
