Can Windmills cause Global Cooling???

During another one of my now frequent brain storming sessions, where I think about everything from the upcoming harry Potter flick, to the electro magnetic pulses generated as a result of a Nuclear explosion, I made a rather startling observation. Wind power which is touted as one of the most promising alternative source of energy, might actually have long term consequences on the regional weather and may be even climate.

Winds, as we all know, are caused mainly by differential heating of Earth, so they can be imagined as agents taking energy (heat) from the hot regions (near the equator which receive maximum solar radiation)towards the poles. Similarly there are seasonal winds and local ones near large water bodies, where they are produced due to high specific heat of water, which makes sure that there is always a temperature gradient during the day and night(Wind blows from the water body towards the Land during day, and vice versa during the night). There are also localized forms, where vertical winds are produced due to high temperature at the sea level compared to higher altitudes.

Now, a wind turbine taps the Kinetic energy of the wind (which is in turn a function of the temperature gradient across which wind flow is taking place). So, at the outlet, the wind will have significantly less speed as compared to the upstream of the turbine. So, for this subdued wind to reach its destination (where it would have reached had there not been a wind turbine), the wind will have to absorb the heat from the downstream of the wind mill. And there we have it, the wind mill has resulted in localized regional cooling.

So, let us assume that we install a sufficient number of wind turbines near, say a coastline. So by above logic, wind flowing from the sea towards the surface will loose a major part of its energy at the turbine(where we are harnessing this energy to produce electricity), and will absorb heat from the surface in the turbines's downstream to renew its onward journey. So, we are seeing a localized cooling effect (neglecting heat generated due to blade friction, which might as well cancel out the marginal cooling thus produced).

So, while also helping the cause of Green energy, the wind mills may also offset global warming.

But it should be noted that in a sufficiently large number they can also influence local weather in the immediate vicinity and the implications of any such trends can not be simplified based on just a few scientific variables.

A new Solar approach...

During one of my off late recurring sessions of black-out, where I stare at nothing in particular, thinking about vague things, I came up with the idea of using Silicon based photo voltaic cells in a new way.

We all know that Silicon being a semi-conductor (having an energy gap in between that of metals and non-metals) gets excited by a certain frequency of electro-magnetic radiation, which leads to production of holes (absence of electrons) which leads to a current in the circuit. Since, photons of visible light are able to provide this requisite energy, solar cells are used in a few commercial purposes as an alternative, clean energy source.

However, this method has one disadvantage. Due to the rotation of Earth about its axis, we do not get the electricity during night or even cloudy days, when there is no sunlight; and even during the length of a day, the orientation of the solar panels needs to be adjusted continuously to get the highest intensity of light, thus making solar energy obsolete for large scale purpose.

Which brings us to my new idea, that of using solar photo voltaic effect to produce electricity from the residual radioactivity from the fuel used in nuclear plants or spent fuel which needs to be disposed off safely, and has no use. After all, the energy carried by the Gamma rays produced as a result of radioactivity has a much higher energy (though that won't influence the amount of electricity so produced) than visual light, so it can very well be used. There are still a few loose points in this theory regarding how to maximise the intensity of the Gamma rays to an extent as to make for economical electricity production (which unlike in the case of visible light will be available round the clock and throughout the year),and if there will be some effect on the Silicon nuclei as a result of this residual radioactivity, which might affect its properties. There is also the issue of practicality of such an experiment, as maintenance of the solar panels will be difficult in such high radiation zones.

Nevertheless, I personally believe that such alternatives need to be considered if we want solar photo voltaic technology to be feasible enough for large scale purpose.

Not a party person...

After spending 3 years at the college, it will come as a surprise to many people that I have attended a total of 4 parties in the last three years, 2 of which were school affairs.

I feel helpless while formulating a valid reason to not attand a party. Not only do I have to make sure that the person concerned does not imagine apparent contempt towards their achievement from me, but also that the reason seems reasonable enough.

Having said that, it is my humble appeal to all my friends that I do not need a party for an excuse to feel happy about your achievement, I already am, and I sincerely hope that all of you succeed in your respective lives. So, please be understanding when I quite unceremoniously or bluntly tell you that I won't attend your job or b'day treat. Nor do I feel the need to throw an exorbitant party, just to make you feel good about my accomplishment. So, if I ever do give a party, it will be a decidedly small affair, most probably in the eternally cheap canteen.

If it is of interest to you, when I was young, I used to celebrate my b'day 3-4 times a year, as a one year wait seemed a bit too long to me. But over the years, I have transitioned into a completely different person. I am uncomfortable in very large gatherings (more than 8-9 people) as it becomes difficult to process all that information at one go. I do not generally dance in large crowds(I do not think of it as dance, some people just keep on jumping at a single spot, while others make wierd gestures with their limbs). So, logically speaking there is not much for me to do at a party.

The following lines may sound as if coming from an obnoxious person and a protectionist economist. I am sure most of my friends will not agree with most of the stuff, as they hold emotional value in much high regard over anything materialistic. But this is a no holds barred narrative, so bear with me. And for the record, I am a supporter of free market economy.

I feel that partying is the most inefficient way of splurging hard-earned money. It does not involve possession of any hard commodity so it does not have any intrinsic physical value. Though I agree, it does fuel demand for the ever-expanding Hospitality industry, I would rather prefer Foreign income in the form of Tourism instead of recirculation of Domestic currency. This may sound protectionist as it invariably supports a decrease in economic activity, and a higher savings rate, these are my real views on the phenomenon of partying.

I am also sceptical (as is my favourite screen character Mr. Sheldon Cooper) of the institution of Gift giving. Not only is it a tedious and wasteful enterprise, it involves careful analysis of the physical and emotional needs of a person better understood by the individual himself. So, I would prefer if instead of spending on a party, you would spend your money on something that you hope to buy for yourself some day.

That being said, do party hard. You have my best wishes!!!

The Plight of CWG: Even our Gods are nervous!

In their monthly appraisal with the executive members of the Heaven, the trinity asked the King of the Gods about the state of affairs in God's own country in the run-up to the CWG.

Lord Brahma: Mr. Indra, We have been hearing distressing news during our daily prayer review. Many of the executives involved in the preparation of the CWG have been blaming excessive rains as the culprit behind the slow construction work going on, floods in various parts of the country notwithstanding. If this goes on, we will have to order an external audit into the state of affairs at your office. Do you have anything to say in your defense?

Indra: Sir, with due respect, I would like to point to the fact that if I had not made it rain excessively in north India, there would have been a drought-like situation which coupled with the inflation would have made the life of the people miserable. Had that happened, then also, the earthlings would have blamed me! And it is a well documented fact that floods have been occurring due to the miserly attitude shown by the dam authorities to store water for producing electricity. They are stocking up for the better part of next year, and release large quantities at the last moment, thus, causing flood-like situations.
As for the CWG, it is unreasonable of them to expect dry days in the middle of the monsoon season! In fact, I believe they should have worked non-stop the previous year when it actually rained less.

Lord Brahma: And why did it rain less the previous year?

Indra: If the Trinity will kindly look at their Order-B6-432, you will find that you had announced the previous year as the Global warming awareness year, and asked all concerned authorities to act accordingly.

Lord Brahma: Oh yes, age hasn’t been kind to us. But still, have you found any solution to this problem?

Indra: Sir, we have started making a list of negligent officials and politicians, that we will give to Lord Vishnu, as and when he decides upon his next Avatar (looking expectantly)

Lord Vishnu: I am sorry Lord Indra, but I do not see that happening in the near future, The avatar is still in the planning stages, there is way too much work to be done, and since, the old magic tricks and shows of supernatural power are not possible in these times, not to mention the strict moral code for celebrities, it will be a while till the next avatar. I advise you to send your agents on Earth to collect evidence against corrupt officials instead. It becomes very difficult during their conviction here, with so many bail applications. Besides, these measures do not look after the present state of affairs...So, ensure that there are no more rains at least for the next ten days both in the construction area and the catchment areas of the concerned dams. Try and keep the weather pleasant, send some undercover agents from heaven, to make sure no more bridges go down at least during the ceremony, and yes, take care of any suspicious activity.

Lord Indra: Do I authorize the agents to use magic, if necessary?

Lord Vishnu: Of course Mr. Indra, how else do you expect the structures to hold!!

Lord Indra: As you wish, sir. On the security front, the “Cow Squad” had been equipped with the modern intelligence gathering apparatus, but the human authorities are adamant at keeping them away from the venues during the games in order to improve the aesthetics of the city. We are contemplating using pigeons for the same.

Lord Vishnu: Yes, hurry up with that.

Lord Shiva: But would it not make people suspicious if there are no hitches at all? The construction is after all sub-standard.

Lord Vishnu: The Indians are wishful dreamers. They won’t notice a thing. And those who do, will be kept under the wraps by the human authorities. I do not think any more glitches will go down well with the rest of the world.

Lord Brahma: That settles it then. End of the meeting. Do pass on to the agents that there will be extra perks for them on smooth functioning of the games.

A fond memory...

The world is suddenly a much brighter and happier place...It is amazing how a single event can change your whole perspective towards life...

It has been exactly 2 weeks since I was placed at Linde and the idea has finally started to sink in. After the exorbitant celebrations (which were happily conducted in the pleasurable company of my best friend--that is me) over the past 2 weeks, I have realized that this is perhaps the first time since years that I have truly felt alive.

Linde is one of the very few accomplishments that I am proud of, more so because of the near perfect and flawless way (which is not the case with what I do mostly) in which I went through the entire process. You see I always appreciate perfection in life, though I am far from achieving it, that one day, I was as near to it as I ever got. It was like a dream day for me.

That day will be etched in my memory for a long, long time. As my name was announced, the world literally went blank. Though I had been expecting the job offer after the excellent interview, the actual announcement hit me like a load of bricks. I had a job! As the newly-placed and their crowd of friends went ahead to party, a still shocked me, caught an auto-rickshaw to catch the 7:30 bus. I do not generally like busy streets and heavy traffic, which is why I avoid the rush hour, but as I stepped out of the auto, the whole world seemed to be a happier place, the normally irritating neon lights gleamed as did the people around me, all of whom seemed to have a permanent smile pasted on their lips. The world had suddenly become a much brighter and happier place to live in.

As the hangover finally wears off, I am left with a few fond memories of the day. Maybe one day, when I am an old (still awesome) man, and recollect my life, I will fondly remember my first interview, the borrowed tie from Saurabh, Vishal helping me tie the knot, while all the other friends offered encouraging advice, me nervously sitting on the desk waiting for my interview, and those golden 20 minutes...

What does independence mean to us?

Every year, the whole country celebrates 15th August as our independence day. There are plenty of articles in all the newspapers and magazines praising our nation's long and prosperous history. There are various concerts on TV, we get to listen to quotable quotes from the world's who's who, that they cook up leisurely, while we smile gleefully and feel proud of our magnificent past. They inescapably go on about our democratic credentials. Every year the Prime Minister and the President talk about India becoming a superpower in the foreseeable future. News channels try to reacquaint us with the freedom fighters. All this is pretty routine stuff.

But, to be honest, 15th August is just another holiday to me. A day when I get to wake up late in the morning. Mess up my daily routine in the best way possible, and may be catch a bit of editorials in TOI. I find it useless to listen to the speeches. I anyway know them by heart.

I am sorry, but I really don't connect with the lousy westerner's idea of the magical and mystical India. "The cradle of Human race" Well, I don't know about the past, but with our burgeoning population, that might very well be true in today's context.

Though I have tremendous respect for our freedom fighters and their ethics; except for a few values, their passion for freedom is all that inspires me. I rather prefer people like Einstein, Bohr, Raman, Bhabha, APJ Abdul Kalam as my heroes. So, I mostly avoid going to independence day celebrations. After all, I can still commemorate them sitting at home...Actually, that's lame...but I am lazy, so that's that.

I have been disillusioned with our democratic values. The only thing that we have here in India is the extremely exaggerated form of freedom of expression, which of course I have been using liberally.

Every general election I try and hope that some other party get to power, but without fail my great countrymen ensure that the same people get to be my rulers year after year. It feels more like Monarchy behind an extremely hideous mask of Democracy. I do not understand, how one can feel empowered by getting to push a button every five years. They should rather feel ashamed of the fact that in spite of practicing their right for the better part of the century, we still face the same problems that we faced when we became independent, with a few stray figures here and there.

And I always thought that I was disastrously optimistic in my views...

and yes, of course, Happy Independence Day to all...:D

The Burden of Tradition and History...

A few days ago, while writing a shopping list in Hindi, I found out, not only have I degraded my calligraphy skills in Hindi (as if it were even possible in the first place), 6 years after I last wrote a sentence in Hindi in my board exams, I can barely write anything in my native language. My Hindi teacher at school had predicted this long ago. Of course, he meant it in a degrading manner. It is significant, that Hindi is the only Indian language I know of, so it is kind of scary that when the need arrives, I won't be able to communicate my ideas in writing through this language. Maybe, I am not a language person after all. It surprises even me that after having lived the whole of my life in Gujarat, I can barely speak Gujarati to this day, and can read it to a certain extent due to its proximity with Hindi.

But, during the same period, my English language skills have improved vastly. So, from where I see it, I have just evolved to get better connected to the Global community.

As the world gets even more globalized; tradition, heritage, and language will eventually become a burden passed on to the youth by their myopic elders. After all, India has more than 2500 years of history and culture; at some point we will have to let go of a few unnecessary things, get our culture in sync with the modern times. If we keep falling back on the excuse of conserving our age-old traditions, the Indian culture will stagnate overtime. Moreover, it is the open-minded questioning, and revolting attitude of the youth that can usher in new innovations both in science and life in general.

Why cling on to diversity and identity, when we all can unite under the umbrella of a global culture? Most of us here may not remember the song Vande Mataram, but if just a song were a yardstick of patriotism, then it would have been a cheap commodity. In an increasingly inter-connected world, we are required to know about the cultures and traditions of other countries too. So, it does seem selfish of our elders to make us remember and value all of their traditions in addition to everything else.

So, a day may come, when like Sanskrit, Hindi may also be lost at the altar of Globalization. It is also possible, that with our sheer numbers and hopefully strong economy we force a diminished version of Hinglish on the world. Either way, life and tradition as we know them now will definitely change over the course of our lives. That does not make us or our descendants any less "Indian" than the freedom fighters who fought for our independence. India, does not live in its languages and culture, it thrives inside its people and the spirit will always remain the same even if their mode of expression changes. That spirit is of humanity.

So, the next time you are degraded by the elders for alienating from the traditions, you can give a logical explanation, that of evolution. We have not forgotten the traditions, we just happen to know their latest evolved version.
