Nitrogen Powered Innovation!!!!!!!!!!!!!!!!

                                                                      
Here i am back to you people with Liquid Nitrogen,yes LN2 can be used as a alternate fuel in automobiles.
The Nitrogen being a abundant component present in the atmosphere and renewable, this way of transport you may see in the future for sure.Let us see the procedures and applications of the Liquid Nitrogen.

The nitrogen present in the air cant be used directly in the engines but the nitrogen when liquified can,Thus it might have certain problems but the liquid nitrogen is one fuel you might be fillin your vehicles with!!!!!!!!!!!!!!!!!!!!!

Liquid nitrogen is generated by cryogenic or Stirling engine coolers that liquefy the main component of air, nitrogen (N2). The cooler can be powered by electricity or through direct mechanical work from hydro or wind turbines.

                             Liquid nitrogen is distributed and stored in insulated containers. The insulation reduces heat flow into the stored nitrogen; this is necessary because heat from the surrounding environment boils the liquid, which then transitions to a gaseous state. Reducing inflowing heat reduces the loss of liquid nitrogen in storage.

Liquid nitrogen consumption is in essence production in reverse. The Stirling engine or cryogenic heat engine offers a way to power vehicles and a means to generate electricity. Liquid nitrogen can also serve as a direct coolant for refrigerators, electrical equipment and air conditioning units. The consumption of liquid nitrogen is in effect boiling and returning the nitrogen to the atmosphere.The tanks must be designed to safety standards appropriate for a pressure vessel, such as ISO 11439

The storage tank may be made of:

* steel,

* aluminium,

* carbon fiber,

* Kevlar,

* other materials, or combinations of the above

Let's start with nitrogen-powered cars. Elemental nitrogen has a very low boiling point. As a result of this, when liquid nitrogen is stored in a pressure controlled environment, it stores a large amount of potential energy. In the LN2000 liquid nitrogen powered concept car, being developed at the University of Washington, the liquid fuel is let out of a pressurized tank, preheated by an economizer which takes heat from the exhaust before it quickly vaporizes, expanding rapidly in an endothermic reaction. This expanding gas is converted into energy that moves the wheels of the converted mail truck by a 15 hp radial air motor.

      This is a basic concept found out by scientists of university of texas, which they found difficult due to following reasons   

The main problem that developers of N2 powered cars have to overcome is that when the nitrogen was expanding, it absorbed so much heat, that the pipes that carried the gas would freeze up. This problem has been solved in the LN2000 by preheating the liquid nitrogen in such a way that ice is less likely to form and insulate the pipes and nitrogen from the ambient heat.

The motivation behind this invention was that although fuel cells were effective at providing electricity with zero-emissions, the cost of a drive train with fuel cell power would be seven to ten times that of a gasoline engine drive train. The inventors feel that nitrogen, once the process is refined, will have a cost per mile comparable to standard gasoline. 

A possible drawback to this method of propulsion is that energy must be spent in order to compress the nitrogen and this energy may not be available in such efficient forms as nitrogen liquid. The following is a quote from the inventors of the LN2000 on that subject:

"The process to manufacture liquid nitrogen in large quantities can be environmentally very friendly, even if fossil fuels are used to generate the electric power required. The exhaust gases produced by burning fossil fuels in a power plant contain not only carbon dioxide and gaseous pollutants, but also all the nitrogen from the air used in the combustion. By feeding these exhaust gases to the nitrogen liquefaction plant, the carbon dioxide and other undesirable products of combustion can be condensed and separated in the process of chilling the nitrogen, and thus no pollutants need be released to the atmosphere by the power plant. The sequestered carbon dioxide and pollutants could be injected into depleted gas and oil wells, deep mine shafts, deep ocean subduction zones, and other repositories from which they will not diffuse back into the atmosphere, or they could be chemically processed into useful or inert substances. Consequently, the implementation of a large fleet of liquid nitrogen vehicles could have much greater environmental benefits than just reducing urban air pollution as desired by current zero-emission vehicle mandates.

Now they have come up with the idea of cooling the liquid nitrogen with heat exchangers and economizers.I say that we can use the energy that is sucked by the economizer to run various electrical parts of engine,This idea might change the whole scenario of LN2.

Liquid Nitrogen has many credits on its side it being the component of air and the system of using the LN2 has recularity it does not cause pollution which is very vital in the future and the energy is has good as petrol you gain 20 to 30 percent of it in consumption,The energy produced during combustion is high and as i said can be used to run internal turbines for super charging purposes.
