Love is in the air

Love is in the air,
It makes you feel so light,
As if you can fly
And over take the overhead flight.

Love is in the air
When you breathe it in
It cleans your lungs
With all that you think was your sin

But this is just a mirage
As wind changes when expected least
This air will pass by
But the mist will persist

I am afraid
That this might be a fallacy
As any change
Will break my fantasy

Awaiting the Beckon…

Awaiting the Beckon…
…And it's just the good old twilight once again,
Bringing, through the lone window of this cubicle,
Onto my tired feet, the shadows from the past;
Faint, yet, profound enough; to emboss
The profile of the tree to which I once belonged …

The air reminds

Of the days bright;
Along with my fellow men, up there,
Playing with breeze was Myself- green;
Adorned with glitzy dew drops,
Toiling day and night, with an ever set mind,
Taking all pains sans an uttered word,
Nurturing my young-ones round the clock,
And guarding them against heat, hail and storms…!

Now today I lie in plight;
Besides the uprooted tree- amongst those disposed;
With expectations both withered and dry-
The expectations that it's now my turn to be nurtured;
And finally blown away by my own kinfolk
Just 'coz I've turned yellow, and can serve no longer.

Yet I kill another day of despair,
Hoping the next rendering a pigeon hole lit-up;
Through what, I'd like my soul to be extricated
When happens, nothing else, but the much awaited beckon…

Solar compressed air engines -- A new future awaits us

This project is actually the combination of 2 different technologies that though centuries old, can help us in breaking through the cob web of pollution & global worming woven around the world by us.

A Stirling engine is a closed-cycle regenerative heat engine with a gaseous working fluid. "Closed-cycle" means the working fluid, the gas which pushes on the piston, is permanently contained within the engine's system. This also categorizes it as an external heat engine which means it can be driven by any convenient source of heat. "Regenerative" refers to the use of an internal heat exchanger called a 'regenerator' which increases the engine's thermal efficiency compared to the similar but simpler hot air engine.

A Compressed air engine is a Pneumatic actuator that creates useful work by expanding compressed air. They have existed in many forms over the past two centuries, ranging in size from handheld turbines up to several hundred horsepower. Some types rely on pistons and cylinders, others use turbines. Many compressed air engines improve their performance by heating the incoming air, or the engine itself. Some took this a stage further and burned fuel in the cylinder or turbine, forming a type of internal combustion engine.

The problem with compressed air engine is that it creates useful work by using compressed air. But the energy required to compress the air is never counted. Here comes the use of Stirling engines. The Stirling engines can use any potential temperature difference to work. We can use solar energy to create the temperature difference by concentrating them by the use of a huge concave mirror on the base of a Stirling engine. That way the rotational energy produced by the engine can be used to drive the bigger piston of the pressure amplifier. This can be used to produce highly compressed air that can be stored for use in compressed air engines, thus reducing the cost of compressed air.

The above diagram shows the total featured diagram of the system. It comprises of 3 important things:

1. Stirling engine

2. air compressor

3. air engine

Solar Powered Stirling Engine:

As mentioned earlier “A Stirling engine” is a closed-cycle regenerative heat engine with a gaseous working fluid”. Actually the Stirling engine works on the basis of Stirling cycle. The Stirling cycle is a thermodynamic cycle that describes the general class of Stirling devices. This includes the original Stirling engine that was invented, developed and patented in 1816 by Reverend Dr. Robert Stirling with help from his brother, an engineer. That age old technology is going to solve the problem of this new era problem. The following graph shows the P~V graph shows the working of a ideal Stirling Cycle.

Idealized Stirling cycle thermodynamics:

In real applications of the Stirling cycles (e.g Stirling engines) this cycle is quasi-elliptical.

The idealized Stirling cycle consists of four thermodynamic processes acting on the working fluid (See diagram):

• Points 1 to 2, Isothermal Expansion. The expansion-space is heated externally, and the gas undergoes near-isothermal expansion.
• Points 2 to 3, Constant-Volume (known as isovolumetric or isochoric) heat-removal. The gas is passed through the regenerator, thus cooling the gas, and transferring heat to the regenerator for use in the next cycle.
• Points 3 to 4, Isothermal Compression. The compression space is intercooled, so the gas undergoes near-isothermal compression.
• Points 4 to 1, Constant-Volume (known as isovolumetric or isochoric) heat-addition. The compressed air flows back through the regenerator and picks-up heat on the way to the heated expansion space.

Pressure vs. Volume graph

This type of plot is used to characterize almost all thermodynamic cycles. The result of sinusoidal volume variations is the quasi-elliptical shaped cycle shown in the Figure. Compared to the idealized cycle, this cycle is a more realistic representation of a most real Stirling engines. The four points in the graph, label the crank-angle in degrees.

The real Stirling cycle is similar to the idealized Stirling cycle; however, the four thermodynamic processes are slightly different. (See graph below):

• 180° to 270°, pseudo-Isothermal Expansion. The expansion-space is heated externally, and the gas undergoes near-isothermal expansion.
• 270° to 0°, near-constant-Volume (or near-isometric or isochoric) heat-removal. The gas is passed through the regenerator, thus cooling the gas, and transferring heat to the regenerator for use in the next cycle.
• 0° to 90°, pseudo-Isothermal Compression. The compression space is intercooled, so the gas undergoes near-isothermal compression.
• 90° to 180°, near-constant-Volume (near-isometric or isochoric) heat-addition. The compressed air flows back through the regenerator and picks-up heat on the way to the heated expansion space.

With the exception of a Stirling thermo acoustic engine, none of the gas particles actually flows through the complete cycle. So this approach is not amenable to further analysis of the cycle. However, it provides an overview and indicates the cycle work.

Air Compressor:

The above diagram reflects the working of the compressor used in this project. Rather than using electricity produced by the Stirling engines we directly transform the rotational motion of the Stirling engine to the compressor. We need very high pressure for that if we use normal compressors we need a pressure amplifier. So rather than using a normal rotatary compressor we are directly coupling the pressure amplifier with the Stirling engine using a crank shaft. This enables us to reduce losses produced by generators and motors. Hence with a surface area ratio of 1:15 we can easily create pressure of about 4500psi. That is exactly the pressure used by typical compressed air cars. When stored in a compressed air chamber it can be used later.

Working diagram of amplifier:

The above diagram illustrates the working of the compressor. It is based on the working of a hydraulic lift. As liquids are compressed to the minimum they replace the same amount of liquid. So when the piston on the wider part is moved by ‘h₁’ the A₁xh₁ liquid is displaced. So A₁xh₁ liquid is displaced from the thinner end as well. Thus the

A₁*h₁=A_2*h₂

ð h₂= A₁*h₁/ A₂

So when A₁:A₂::1:15 then h₁:h₂ :: 1:15 thus increasing the pressure by 15 times. Thus the result is a highly pressurized gas that can be used to run air engines.

Air Engine:

A Compressed air engine is a Pneumatic actuator that creates useful work by expanding compressed air. They have existed in many forms over the past two centuries, ranging in size from handheld turbines up to several hundred horsepower. Some types rely on pistons and cylinders, others use turbines. Many compressed air engines improve their performance by heating the incoming air, or the engine itself. Some took this a stage further and burned fuel in the cylinder or turbine, forming a type of internal combustion engine.

This is engine have an estimated efficiency of 50-70%. Thus it is really useful in creating a good quality petrol engine replacement. It is practically being used in applications like air cars that are being used since last 4-5 years commercially.

Future expectancies:

If the solar energy reaching the cars’ top would be enough to drive the amplifier, we can make a car that can refill its compressed air tank in day time and use it to drive the car anytime. According to calculation made based on theoretical data, the energy reaching the top of the car would be just enough to make a car with an average speed of nearly 40-50 km/hour.

If it would not be enough we can make bigger solar energy compressed air stations around the world as there are gas/petrol tanks. They can fill the air cars cambers with air in 4-5 minutes that is as per now available air cars enough for 200 -300 kilometers.

Conclusion:

This project if completed would provide the earth with an old solution to the new problems of global warming and pollution using THE renewable source of energy (SUN). It is some thing that can change the current economic transitions by reducing the use of petroleum product.

confused smoke

confused smoke
give my lungs a poke
every time i sink it in
it brings me closer to a stroke

even then i fag
i dont know why i have this nag
and every time i take it in
it gives me a doppers tag

its nunsence that
i m burning my fat
what i m actually doing is
a race of cat and rat

i m confused in
what i am doin
but what i know for certain
is i m not doin good to my kin

it is my life
i can cut it with a knife
n i m waiting for my end
9, 8 , 7 ,6 and five

confused in love

my love my life my dream
you are mine and only mine
is what i should say
even with a chill in my spine

they say that
u see her n only her
in day, night, dawn dusk
in fins and fur..

i never see her
i rarely talk
i never dream abt
a wonderful night fuck

but i still love her
i know it in my heart
even if i dont carve her name
on my hand palm or shirt...

i love her
as i love success
i love her
as she is the reason behind my pace

i dont bother
if i will marry her or not
but i will always carry
all her wonderful thought

i told her once
that i love u
she told she was confused
and needed time too

i cried i drank and i smoked
and slept that night weeping
but then i realized
now i have new reason for living

life is not
the way u want it to go
life is always
the way u mold it and show.....
