Maglev Trains-The Solution to Coal Pollution
Transcript of Maglev Trains-The Solution to Coal Pollution
coal is nonrenewable
a fossil fuel that is formed from materials that have been subjected to geologic heat and pressure over millions of years
coal is washed to remove impurities, and then transported to the power plant
coal is burned in a boiler at the plant to produce steam
steam goes through a turbine to generate electricity
burning coal releases greenhouse gases in the air, contributing to global warming
it may also affect air quality
How does coal affect the environment?
Coal can harm organisms by adding toxicants into the air. This toxic air could get into human lungs, and could cause lung cancer and do neurological damage to humans. Also, aquatic organisms can be harmed if coal ash gets into their ecosystems.
Maglev Trains-The Solution to Coal Pollution
Maglev is a new transportation method. They are lifted by magnets, and don't need physical contact on the guideway. Maglev vehicles don't need engines and do not burn fuel. Instead, they are magnetically propelled by electric power put to coils located on the guideway.

In recent years, burning coal to produce electricity has been causing more and more pollution. CO2 levels have been rising in the atmosphere, contributing to global warming. Additionally, burning coal causes air quality issues and it requires a lot of water to produce electricity from coal, between cleaning and other processes necessary. If coal ash is accidentally or intentionally released into aquatic ecosystems, it may harm the organisms thriving in it. We believe that introducing Maglev transportation will help reduce this problem and lessen the amount of harm that producing electricity by burning coal causes.
What is Maglev?
THE PROCESS OF HOW COAL GENERATES ELECTRICITY
What is coal?
How is it used to generate electricity?
How Does Coal Effect Organisms?
Burning coal affects the air quality and sends many gases into the air, such as carbon dioxide, sulfur dioxide, nitrogen oxides, and mercury compounds. These gases are contributing to global warming by increasing the greenhouse gases in the atmosphere.
How can Maglev Transportation be implemented in our community?
Water Resource Use
What does it affect?
To wash the impurities from the coal, large amounts of water is used to clean them. Also, power plants require water to produce steam. When water is removed from habitats, organisms are affected by a smaller source of water to live or drink with.
What positive impacts does Maglev transportation have?
Maglev is very energy efficient. Unlike automobiles, trucks, and airplanes among other forms of transportation, Maglev does not burn oil or fuel, but uses electricity instead, which can be provided by any of many different types of power plants (nuclear being the most practical and efficient). On top of that, Maglev vehicles emit no pollution. Even if they get their electricity from coal-powered or natural-gas-fired power plants, the CO2 that it emits is much less than that of all other modern forms of transportation such as cars or airplanes, due to its very high energy efficiency.
For Maglev transportation to be implemented in our community, we will need to replace our existing railroad tracks. Due to its use of magnetic levitation methods, which are powered by electricity, our current railroad tracks will unfortunately not suffice. Additionally, we will need to purchase the machinery/train components and materials necessary to build the tracks. While it may be costly, it will be worth it in the long run because it will conserve much energy and provide a means of mass transportation that creates less pollution.

Greater demands for electricity needed for various reasons to support our modern world means greater amounts of electricity must be produced, and in the case that they are produced from burning coal, many greenhouse gases are released into the air. These greenhouse gases contribute to global warming, which is causing many problems to arise on Earth, such as ice caps melting, leading to rising sea levels, and climate change, which affect organisms in certain areas. However, by introducing Maglev transportation, we can greatly cut back on CO2 emissions, because Maglev transportation does not burn fuel and is very energy-efficient, meaning that it does not require much electricity to run and it uses it efficiently without any waste. Also, Maglev will provide a means for mass transportation,successfully reducing CO2 emissions due to the fact that it emits no pollution and many people will not have to take or drive vehicles that use natural gas and produce carbon dioxide as a waste product. Since Maglev vehicles are very energy-efficient, even if they use electricity from coal-fired plants, the resulting CO2 emission is much less than that of other forms of transportation, such as cars or airplanes. Therefore, Maglev transportation would be a great solution to our atmospheric and global pollution.
