Electricity is taken for granted in the twenty-first century. Appliances make our life easier and lighting allows our days to extend longer into the night. Electricity is increasingly making its way into, and point to point. Electrified transportation “Electrified transportation” is increasingly becoming more accepted as the norm rather than the exception. “Ultra capacitors” developed to run electric cars have greater energy density than traditional batteries. Technology that uses a “magnetic gradient” to develop permanent magnet-powered impacting, our transportation networks and how we use them. Electricity helps satisfy the intent and goal to reduce carbon emissions given off by fossil fuel-burning combustion engine vehicles. Mass transit running off electricity helps resolve the rush hour gridlock dilema of moving large numbers of people from motors is quickly catching up to the electrically-powered engine, although electric motors also depend on magnets to some extent. The magnetic incline operates in the same way as changes in hydropower altitude or for an electrical voltage. Escalators and elevators, airport moving sidewalks, and subways and monorails are electro-magnetic operating systems. Similarly, electric windows go up, windshield wipers wipe, and door locks unlock with the aid of magnets. GPS navigation and radar systems also utilize electromagnets [6]. What is an Electric Vehicle? Electric vehicles use electric motors to drive their wheels. They derive some or all of their power from large, rechargeable batteries. The distance an EV can drive between recharges is known as its range. Electric vehicles (EVs) are more energy efficient during use than petrol or diesel vehicles, and produce less air pollution.

This design, called Induct rack, aims to lift and propel the train without constant electrical energy being used in the track or the train. This design uses special arrangements of permanent magnets on the train and coils of wire in the track. Although a small external force is required to get the train moving at first, once the train reaches a minimum speed, the motion of the train will induce currents in the coils of wire inside the track that will provide the lifting force needed to float the train. Therefore, no long-term power supply is needed to support the train, just its own motion. While a full model has not been built using the Induct rack design, NASA has invested in the design in hopes of launching rockets using maglev technology. [5]
Electric traction had numerous advantages over steam railroads. One major advantage was electric locomotive’s ability to pull heavier loads than steam locomotives (Bezilla, 30-31). One statement from electrical manufacturers’ stated that an electric locomotive could pull from five times its own weight on a 2% grade, whereas a steam locomotive on the same grade could only pull two times its own weight (Bezilla, 31). In addition to this, the electric motors could sustain higher currents for a short time in order to increase horsepower dramatically; steam engines had no analogous feature (Bezilla, 31). These factors combined allowed for electric locomotives to accelerate more rapidly, even while pulling more weight, than steam locomotives (Bezilla, 31). The electric motor also had less moving parts and thus needed less maintenance than complex steam engines (Bezilla, 31). For example, the Pennsylvania Railroad’s electric locomotives in 1940 were typically running 90% of the time, but the steam locomotives that the electric ones replaced had only ran 69% of the time (Bezilla, 32). The...

Electric Cars use the energy stored in a battery (or series of batteries) for vehicle propulsion. Electric motors provide a clean and safe alternative to the internal combustion engine. There are many pros and cons about electric cars. The electric vehicle is known to have faster acceleration. They produce no exhaust.
With the opening of America’s first roller coaster in 1873, a new innovative market was introduced into the American industrial market. With it came a new set of challenges that pushed the limits of the engineering methods used at the time. Oddly enough though, America’s safest roller coaster ever built was also the simplest; the Mauch Chunk Railway was originally used to bring coal down the mountainside of a Pennsylvania mine. The now unused 2,322 feet of track was re-opened a few months later for the purpose of carrying passengers down the side of the mountain. The rail cars used did not have brakes or an engine; they simply used the force of gravity to take the train and its passengers, sometimes at speeds upwards of 60 miles per hour, down the side of the mountain until it came to a rest at the bottom. “The railway offered spectacular views of the Lehigh River and the Blue Ridge Mountains for the region's visitors to see. The area became a large Nineteenth Century tourist attraction and people came from all over to be thrilled by the M.C.R.” (Sandy). Throughout the ride’s 56-year span of passenger operation, not a single injury was reported. Since the ever-simplistic entertainment methods of the 1920’s, our industrial capabilities have grown in geometric proportions; however the one problem is they have been severely lagged by the safety and control systems that govern them. Recently, however, advancements in computer technology have yielded a drastic improvement in these control systems that have allowed ride designers to design increasingly safer and more reliable ride systems.
The rail systems put into place in Chicago have always been a major factor in freight transportation. The city provides a centralized hub for the railways throughout the country. After a long run the system is bound to find flaws as old technologies are passed by new ones. The existing railroad structures have in time taken a toll over the years of service. “The railroad system of Chicago has been around for a long time now. After many years it has gone past time time of despair. With the new project it is hoping to bring the popularity back to where it once was” (Chicago Transit Renovation to Improve Service). This update needed will guide Chicagos railroad system into the future. The city also has to take a look on how it is going to keep up with the constant increase of railcars on their tracks. With the new technologies of the future Chicago can only make their infrastructure better. The aim is to stay on time with the railcars to diminish the amount of overcrowding presented in the old rail systems in Chicago.

The earliest prototypes of self-powered vehicles began in the 1700’s with the first one being built by Nicholas Cugnot, weighing over 8000 pounds and clocking in at a top speed of 2 miles per hour (Bottorff). This large size and slow speed meant that it was impractical as an automobile. Several other prototype vehicles were built in this style by various inventors but were so heavy that they required metal rails to drive on, and so over time they evolved into trains and locomotives (Bottorff). Trains and steam power continued to develop and interest in a self-powered vehicle that didn’t require tracks faded, until the mid-1800’s when new developments in power sources encouraged the development of the automobile.
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.
Imagine that you’re driving on an open highway in the middle of summer. All you see in front of you is asphalt for miles and miles. The windows are down and your favorite song comes on the radio. You’re behind the wheel of a Tesla Model S, the newest electric car that can go from zero to sixty miles per hour in 2.4 seconds. This will soon be the future of all motor vehicles. Electric cars are beginning to have colossal impacts on our society because of their energy efficiency, performance benefits, and the fact that they are less harmful to the environment. In the near future, electric cars will dominate the road and eventually the planet’s overall need for oil will decrease immensely.
Electric cars are becoming increasingly more necessary, and have more advantages than disadvantages. Electric cars help to decrease the noise, pollution as they are much quieter. They do not emit any (or much less) carbon emission than petrol cars. Electric vehicles are the greenest mode of transport in the personal transportation industry. For each litre of fuel used in an engine produces more than 2.5kg of CO2. CO2 will be produced by an electric car but still a very little amount. It is also possible to use renewable power or a green energy supplier in the electric car. Thus it would lead to less polluted and safe working environment for all of us. However, safety is a big concern with using vehicles. The fluids in the batteries actually take impact better than a fully made gas car because it is not that flammable. Petrol cars and diesel cars are more flammable than electric cars so they are greater of taking impact in the event of an accident. I think that this is a very good reason because fewer people would get injured or hurt. This would save money because electricity is cheaper than gas and electric cars are easy to operate. Also is very ECO –friendly which mean that it is cheaper to run and have to pay very little road tax. In a pure electric vehicle there’s nothing combustible and have far fewer moving parts than you would find in a petrol or diesel car.
Now, what are electric vehicles really? Simply put, electric vehicles are vehicles that are powered by an electric motor instead of an internal combustion engine. Electric vehicles use electricity as the “fuel” instead of gasoline or some other combustible fuel. The electric motor in an electric vehicle converts electricity, usually from a battery pack, into mechanical power to turn the wheels. Major auto manufacturers are producing high-performance electric vehicles not only in the form of cars but also in a wide range of styles and sizes, including, mini-vans, sport utility vehicles and pickup trucks.
The introduction of more commercially available diesel and fully electric vehicles has started to impact the sales figures of hybrids which is surprising to me because of the natural deficiencies that the hybrid vehicle has to overcome to be more effective both in environmental savings and cost savings to the end user. I believe that some combustion automobiles offer equal if not greater environmental and cost savings over hybrid vehicles. I believe this because the manufacturing and disposal process for batteries is very damaging to the earth, and the longevity of the parts is less than that of a normal vehicle. Also, if measuring environmental impact by comparing fuel consumption, many diesel cars are able to achieve greater miles per gallon than similar hybrid vehicles.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
Hybrid cars are already a well-accepted part of the landscape but many other radical new technologies have been launched or are under development that will revolutionise travel in the cities of the future. Solar-powered buses and trains that obviate the need to build new tracks by straddling existing highways are two of the more eye-catching projects in the
