Future of Transport (electric)

Future of Transport (electric)

Many concepts exist on how the future transport system will look like. Engineers are working hard to improve the present transport system especially the powering of the transport system to make it more efficient. Over the coming decade, the thought of getting to work on time, getting to class on time and also going for vacations will be much easier. Cars will be astonishingly driving themselves using the required routes while the trains will use magnetic rail systems moving at 800 miles per hour.

New technologies on transport will make the transport system safer and more effective. The department of Transportation’s Research and Innovative Technology Administration is working towards ensuring that the technologies will be unified safely to the existing transport system. There will be less congestion, lower transport cost and less pollution.

Radio thermal generators

Radio isotopes have been there and are used as alternative fuels. However, their use on land is deteriorating since the isotope can be stolen and it also causes environmental destruction if the unit is opened. Decay of radioisotopes produces heat and electricity especially where sun is weak and where low temperatures are a problem. Radioisotopes used as fuel are not reliable enough to radio thermal generators since they end up making the radio thermal generators not to sustain the atomic chain reaction. On the contrary, they end up producing electricity from Earth as a fuel.

Bio diesel

This is a mixture of petroleum diesel and oil from vegetables. They reduce air pollution by producing less carbon. This is when compared to standard diesel. Biodiesel are cheaper compared to petrol, and they are also more energy efficient hence drivers prefer using them than petrol. However, biodiesel cost is very high compared to diesel; another problem is that the farmers start growing biodiesel plants instead of growing food crops thus causing food shortage.

Ethanol

Ethanol is also used as an alternative for petrol. It is produced from of gasoline and propellant from grain. Its emissions are environmental friendly since there is less pollution. The farmers also highly benefit from the sale of the propellant grain. However, the ethanol has its own disadvantages because some people argue that the poisonous gas emissions from the grain production are more than that of the ethanol emissions (Severinsky, 1994).

Hybrid cars

These operate from a mixture of gasoline powder and electric power. The advantage with these cars is that they highly save the fuel costs since their engine is efficient and their battery stores energy when moving. The disadvantage with the cars is that they are very expensive to acquire.

Hydrogen

This is an alternative form of fuel which replaces petrol. Hydrogen comes from water which means it is a renewable fuel which is fair in cost and is also non- exhaustible. The emissions from hydrogen fuel cars is 100% environmental friendly. However, the manufacture for the hydrogen fuel cars is rather cumbersome. In addition, hydrogen is very explosive, which highly endangers human life.

Nuclear power and radio thermal generators

This is any technology used to generate energy from atomic nuclei by means of nuclear reactions. Nuclear power has got many uses: it can be used to generate steam pressure, which can be used to generate electricity. Electricity from nuclear reactors can be used for propulsion in space. Power generated from nuclear fission has been used over the past time by spacecraft, however, of late there has not been a nuclear reactor sent to the space. Electricity is being currently used in moving electric trains and cars; electricity is a clean form of fuel which does not pollute the environment. The electric trains and cars do not emit fumes which cause environmental pollution; their movement speed is also very high. However, they are very expensive to acquire.

Super conducting vacuum trains

Over the past years, very fast maglev train systems have been operating though they have not fully become pervasive. The reasons are because the engineers do not find any need to replace the existing railway systems. Another reason may be due to lack of enough money to replace them. However, the evacuated tube transport (ETT) structure envisages superconducting maglev trains, which works in expatriate ducts moving at a speed of six thousand, five hundred kilometers per hour. It takes a very short time to cover a long distance. This is evidence that the ET3 train will be 50 times faster than the current train and vehicles. A 500 km/h (310 mph) vacuum train has been projected in Switzerland which will be much more efficient than the current transport means today (Brownstone, Bunch & Train, 2000).

Trains started operating from steam to diesel. Nowadays, diesel trains have been replaced with ultra-low-sulphur diesel, biofuels and hybrid technology. Liquefied natural gas (LNG), whose another name is propane, has also replaced the steam and diesel driven trains. It has low costs, which make it striking especially to those industries with noteworthy energy cost. In addition, the advantage of Liquefied Natural Gas, unlike diesel fuel is; harmful emission reduction has led to the encouragement of use of Liquefied Natural Gas by the environmental sectors since carbon emission is reduced by 30% while nitrogen emission goes down by 70%.

Methanol

Methanol has many benefits that make it attractive to many. It has a high performance and many safety benefits. It is an environmental friendly gas, and it is not flammable. However, those who opt to use methanol as a form of fuel are flexible to use any other fuel (Chan & Chau, 2001). Though it is made from a natural gas, methanol can also be manufactured from coal and wood. The drawback of methanol is that it is toxic.

String transport system

It is highly being worked on which will act as an alternative to straight structures. The idea is founded on what is likely of heavy-duty that are placed above the ground but are electric wires, which instead if transmitting current they act as a support for carriages. The supporters of the system find the system more advantageous in terms of cost where it can be 10 times cheaper than a railway, maglev system and also the monorail system (Wyman & Bespalko, 1997).

Tubular rails

This is Robert’s C. Pulliam’s project whose idea is taking above ground rail. The train normally carries the paths while the rolls and motors are enclosed in the rings where the train passes through at a speed of up to 240Km/h (150 mph). The advantage of Tubular Rails is on its construction, which is 60 percent less than that of standard urban train networks. Another advantage is that the rail will cause slight disturbance to the present network. The third advantage is that the technology for making the Tubular Rail is readily available and not very expensive. The tubular rails reduce environmental pollution (De Luca et al., 2009).

The straddling bus

The straddling bus, roll on its stilts above the traffic by means of small pathways, which will be positioned between the lanes of traffic. It is one of the most exciting transport means which highly reduces the urban congestion. The travelers get on and off at the bus stops without any troubles. This system will add the capacity of people carried in town roads. It will not cause any disruption to traffic. The bus will be electric causing less pollution in the air.

Space elevator

This aims at reasoning means of getting to the space. There is a variety of designs, but the main component of making the space elevator is a thin tether from a light material. That is, the carbon nanotubes which spring from near the earth’s equator to a distance of 60000 miles into space. The cost of cargo transportation will be reduced according to the International Space Elevator Consortium. If worked on today, by 21st century the idea will be transformed to a reality. The Tokyo construction company has got ideas for making a space elevator by 2050 which will carry approximately 30 passengers (Brownstone, Bunch & Train, 2000).

In conclusion by the year 2050, the transport sector will have highly changed to the better. There will be fewer cases of poisonous gas emission from the transport sector. These gasses are a threat to the ozone layer which protects us from the dangerous ultra-violet rays of the sun. The human health will no longer be at a high risk of getting these dangerous diseases from exhaust fumes. People will reach their destination in time due the fast means of transport being worked on today. The engineers are working hard for the betterment of future transport.
