Lets say a decade before, you were told to replace your old filament bulbs with that time favorite tube lights. You would surely hate the tube light and loved the bulbs for one sole reason that is flickering. The tube light may take even minutes to turn fully on and give a constant light dissipation. This was not there in bulbs even though they were inefficient in converting the electricity to light. So the main problem with the tube light was flickering. This was rectified in the new generation CFL's.

Why CFL lamps don't flicker and have spiral structure ?

How it is different from the conventional tubelights and why does it not flicker when it is turned on?

Let's find out!!!

The Idea behind it :

Before we know why a normal CFL ( Compact Fluorescent Light ) does not flicker, lets snoop into its principal how it really works.

CFL's can be divided into two main parts. One is the ballast which can be magnetic or electronic, which is usually covered in a case. The second one is a gas filled tube, which you can easily see from outside.

To remove flickering we generally use electronic ballast instead of magnetic ballast because they are much faster and compact. 

Lets have an overlook of what electronic ballast comprises of. They contain a small PCB with rectifiers, a filter capacitors and generally two switching transistors. It follows the following steps:

1. Incoming AC current is first converted to DC.

2. It is then converted into high frequency AC by the transistors.

3. The resulting high frequency is applied to the tube.

Working :

The resulting high frequency excites the electrons inside the CFL which has mercury vapors and argon inside. It is also coated with phosphor. This gets illuminated when the electron falls on it. So larger the surface area it is coated, more faster will be its illumination time. The sharp edges at the spiral also boost up the speed of the electron thus accelerating it. Thus we don't see the CFL's flicker. This is not there in the conventional type of tube light.

Disadvantages:

1. Since it uses mercury vapors, its disposal is not Eco-friendly.
2. Since it is a point source rather than a line source of light like tubelight, the light intensity in all directions is not same. So near the CFL the intensity is more.

This is the season of firecrackers bursting and those rockets mesmerizing the sky. The colorful shows presented by these firecrackers is never a miss. It always attracts millions and I guess you never want to miss a show. But the beauty doesn't come with a 'beast' besides it. Isn't it?

The pollution it causes over a short span of time during festive season is tremendous.  The pollution levels it causes reaches almost above average levels. But if you insist me to stop bursting crackers, I won't even heed you. The same situation applies to most of us. There should be some other alternative to bring down the pollution levels during this time. Else environmentalist break on us blaming that we were the ones causing major harm during the period.

So in short it should be an Eco-friendly one even if we burst crackers. The main thing that we can bring down the level of pollution is by cutting of those harmful gases. Is it possible? For every problem there is always a way out!!!

The Idea:

We speak of Eco-friendliness, so we are going to seek the help of our nature itself to solve this issue. Here pot plants are of great use. The Aloe plant is a great air purifier. A pot of Aloe is equivalent to the nine biological air cleaners. So it turns out to be fruitful for those having respiratory problems. If we keep this plant near the person the gases are automatically absorbed by it. The artificial purifiers are of no use. It absorbs gases like carbon dioxide, carbon monoxide. And the great advantage of this plant is that when the normal levels of toxin in the air increases, then this plant turns spotted.

So you can buy one or two pots of Aloe and keep it in or outside your home.

The second is little time consuming and you already have to be prepared for it. The corporations can also take a little measure before hand. You can plant rubber trees along the road or in the residential area. Rubber greatly reduces the granular dust and also absorbs most of the toxic gases like carbon dioxide, carbon monoxide.  

Flash powders can be used as this burns up fast leaving lesser traces of gases. Sulphur absorbing materials can also be added to avoid forming of sulfur dioxide in the atmosphere which is a major pollutant.

If you have your own methods to have a Eco friendly festive season then it well and good.  Else you could follow some other alternative.

THE AIM IS TO SPREAD THE MESSAGE LIKE THOSE FIREWORKS COLORING THE SKY.

The parties never stop you from eating loads of food. You get what you want and that too for free. So you don't even realize how much you are eating.
Sometime you eat too much and there is not a inch space even for a drop of water to get in. Still if it is your favorite food you crave for more and more. The human desire is never ending. If you still want to eat more then the rest of your day you will spend sitting in a place. But if your heart still craves for more and you don't want to get digestion problems, here is an answer.

The Idea:

All you need to do is to drink a bottle of soft drink after eating all the delicacies of the treat. Since soft drinks are usually acidic in nature, it will aid you in digestion. You don't even require the appetizers, that you eat after your meal. It can be a set back to the persons having gastric problems as these soft drink are usually aerated to a great extent. So it is generally advisable for the persons with gastric problem not to consume much of soft drink.
You feel lazy initially after eating food. You feel very sleepy. This is because the oxygen required to digest the food is very large. So our body tends to cut off the supply to the other parts of the body so as to maintain a good amount of oxygen supply to the stomach. We tend to sleep, so as to consume minimum amount of oxygen by other parts. So when you eat more you tend to sleep more. It takes lot of time to digest the entire chunk of meal that you ate.
But you will feel light and easy in short span of time just after you drink the soft drink. You will be energized to eat even more as the stomach gets empty very soon. The large amount of food that you need to digest is digested quickly with the aid of extra acids that you get from these soft drinks.

Now you can go to multiple parties and no worries. You can eat your heart content. So one is going to stop you, not even you stomach. If so just remember to have a drink of the soft drink. And its the time to party hard!!!

There is always a hype when you go for a treat, no matter how small it may be. The person who gives one, thinks of saving his pocket but the other thinks of eating a sumptuous meal. Burning a hole in the pocket is a sure, for the one who gives the treat. But if I give you an idea that could save your pocket and help you to cut their meals and their wicked idea of robbing you of your money, you will surely love to know it!

The idea is plain and simple. You can do this trick with just a soft drink.

IDEA:

Before ordering the menu, just order a soft drink for all. And yes, believe me, this will help you a lot, to save few thousands if you are giving a party to large number of them. You would be puzzled and ask me a question, does this really work out?? You all have this question to ask, so let me explain the overall idea behind this.

Since all soft drinks are usually aerated and CO2 is compressed inside to give you a fizz, when you drink a soft drink before a meal it fills your stomach with gas. The compressed gas is released due to the decrease in pressure and thus decreases the solubility of the dissolved gas. Since the gases occupy more space than in their dissolved form, your stomach swells up. Apparently he feels that his stomach is full and he wouldn't be able to eat more. This makes them less hungry, as there is no space for the food to enter. This is just for few hours and again they will feel hungry. But no problem for the one who gives the treat, his treat will be over by then. Since there is no solid food to digest, the process of digestion doesn't take too much time. The one who thought of looting him will have to be hungry again.

The cheapest idea to save a person from getting into more debts for a mere treat and parties.

But.............

THE REVENGE IS SWEET THOUGH.

Wait for the next article for those who were betrayed by this idea by one of your  friends!!!

We feel lazy even to go upstairs and call someone. When someone pesters you to go to a shop and bring something you immediately take the mobile in your hand and there you go, you call the shop and ask for door delivery. But even to take that mobile while you are watching your favourite serials, is hard. Isn't it guys?? The most probable answer I know that most of us would say is YES!!! What if all things happen as we like, or let me be a bit specific, what we think?

Most of us surely will agree upon the idea. But will this be a reality just in cartoon shows and movies. Why can't be this real? May be it can be turned reel to real one. Yes, this is possible my friends.

The idea:

We all know that our body too sends its own signals. Let me be a bit specific on these. Our body sends information to other parts through small electrical signals. Each action is executed by our body only when an electrical impulse is sent by our super powered brain. This makes our brain a control system of our body. The thoughts that generate, to the movements we make, all are controlled by our brain. So we can be pretty much sure that most of the action is controlled by our brain. So why can't we send messages not within us, but outside us. 

Yes, it can be true and also be practically implemented using what is called transcranial magnetic simulation. This thing uses weak electromagnetic induction to induce weak electrical signal in our brain. This device can be attached to our motor cortex, part of the brain that controls the movement or this can be connected to the limbic system of our body that controls our emotions. Now whatever you feel will be generated by the brain in the form of electrical signals which in turn induces the set up which will detect the type of emotions you are in. 

Now if this is detects what the emotion is, then it can be sent to a device of suitable form as an output. Say, if u want to dial a number on your phone then you just need to think. Then these signals will be detected by our system and sends it own electrical signal. If this is connected via Bluetooth, then you can easily access your mobile.  

The main practical difficulty we may face is the strength of the signal. The brain sends very weak electrical signals which are hard to detect. Since the signals are very weak to detect, there is an added possibility of mixing of some other signals at this magnitude. So it may lead to adversities. If we eliminate this mere disadvantage then it's a technology that is going to shake us all.

It will be a time to think from the brain and not from the heart, I suppose!!!

You like it or not, I hate winters. They push me inside my house as I cannot even go out freely. Even if I had to go outdoor, those jackets and sweaters make me sick. They are too heavy to wear and they are not at all handy. I feel better to stay at home rather to wear all those heavy things on me. Making these things light I was caught up with one thing. The idea seemed to be nice and very effective too. What was that idea? let's find out!!!

THE IDEA:

Did anyone even heard of something called AEROGEL ? What really is this thing?

This is also known for its name called frozen smoke. It is world's lowest known density solid, which is made of 96% of air. It is basically just a gel made from silicon, except all the liquid has been taken out and replaced with gas instead. It is hard to see it or even hard to feel, but if you poke it is like a styrofoam.

But it is a wonderful insulating material. If we can make jackets out of it, then it will be a great solution to our problems. But the problem is that it is very good insulator. That means if you wear a jacket made of aerogel then you will sweat to death. In simple words, you will sweat when you wear this at Mt. Everest too. So we cannot make a jacket completely made up of aerogel. So we have to add some other material with it, so as to make ourselves suited to it.

Now there is an extra advantage of this material. It can withstand high amount of energy. For comparison, it can withstand a direct blast from two pounds of dynamite. We can also use this as protection cover, but again there is a drawback, it works very well as a bad conductor of heat. The outer cover of the car can be made of this material and this will prove to be a changing point of security concerns. Since it will protect the car from direct blasts from dynamites and it is literally invisible and light, it is added advantage to the security concern.

The next area in which this material is used to an extensive usage is thermo flask. Since this is the best insulating material, this will keep the material inside almost to the same temperature for days together.

There are more and more things turning up using this material. The future is yours. It's the time which will prove this right.

TRUTHS BEHIND THOSE MYTHS- PART 3     

You fear them or not, but I do fear them the most. I think this situation is same for most of us reading this. Even if we hear the name " snakes" we tremble like anything. Don't worry, we live in multi storey buildings where the snakes cannot even think of creeping through. But in the past, neither they were living in those sky scrapers nor the population of the snakes were low enough.

So how did they manage to overcome this situation. If you ask me, I would say they were experts in this. I know how, but if you want to know read on further.

Their method:

If your guess is that they killed them all, then you are wrong. Just after one mating the female snake can lay eggs up to 100. So among them, even if one snake survives, it produces its next generation. It makes the growth rate exponential. Then how did they prevent them?

They exploited the idea, that the snakes generally live in snake hills and burrows. The snakes find their mate using smell and they will leave their hiding only for the search of food. If they find their prey they won't leave their habitat. People at that time placed MILK and EGG near the snake hills. A question would arise in your mind that the snakes don't feed on this then what's the use of placing this. The answer is that milk and egg have a strong odour that confuses the snakes when they try to find their mate using fork in their tongue which detects smell and taste. So they won't be able to mate with its counterpart as they can't even detect them where they are. 

The second problem is that if they leave the place, the whole idea is wasted. So they used to place or put some food inside their burrow or the snake hill. So the snake never comes out of its habitat. As a result the snake population falls drastically over months.

Even if one escapes from this cow web of their ideas, they had the answer for that too. The wall was coated with turmeric paste near the lower part. The snake doesn't like the smell of turmeric, so it changes its path. So the people inside the house are totally safe!!

Now you to know whats meant by  " LIVING WITH NATURE"

Mere touch can heal you

 http://fiction.divilabs.com/2013/08/mere-touch-can-heal-you.html 

 We change the world with the flick of a button. We explore the space with a push of a button. Small things can't be underestimated. The potential what a small thing has, can't be imagined what huge things it can do. It maybe a small atom producing tons of unimaginable power converting itself into other atoms.

                                    

The most surprising part is that while providing this great energy the atoms convert itself into another atoms. In fusion the lighter hydrogen atoms fuses into the bigger helium atoms. The bigger uranium into fissions out to produce smaller atoms like plutonium, lead etc.

One thing that caught my attention is that ONE ELEMENT CAN CHANGE INTO ANOTHER ELEMENT.

Then why can't we produce the so called "rare" earth metals which we need it badly!!!!

If hydrogen gives helium, uranium gives plutonium then what can give us gold or diamond???

It is a new area where we can scratch our heads out!!!! What if we can get tons of gold and diamond using this known??? Wouldn't be that a mind freaking thing???

THE ULTIMATE FACT:

The whole system in this world moves towards the lower entropy and thereby moving towards greater stability. Since bigger atoms break down to smaller atoms for greater stability so as those smaller ones combine to form bigger ones.

Gold, one of the most stable element can be got using fusion reactions as the atomic number of gold is much higher. If suitable conditions are maintained during the process of fusion then we can achieve our desired results. 

The sparkling diamond can be yielded by the fission process of bigger atoms.

THE TRUTH BEHIND THIS FACT:

·         Is this really feasible than extracting the gold from the earth??

·         The fusion and fission reaction needs special care and this technology is greatly condemned worldwide for its ill effects.

·         The whole thing has to be properly catalysed to get the desired product otherwise it may lead to other reactions.

·         This process may yield may more elements which is not of our interest.

When we were small and were mendling with those insects hanging on the roof tops, little did we know that they could be harmful too. Those hooting sounds,that sticky webs of spiders, sometimes it seems irritating. Usually we seem to curse those small things or even think why they were here along with us. Little did we know the potential of those small insects.

The one thing that caught my point is the strength of the spider web, a special species of spider to be specific,major-ampullate (dragline) silk to be pretty more specific.

MY IDEA.

Many of you might heard that the web of the spider is stronger than the steel. It may be used in the bullet proof jackets and other such things. But my idea is little different. We culture the silk worm to get silk out of it. Why can't we culture these little "pests" ???

• We can culture these little ones and take out their  precious possession, well simply called web.
• Then it can be spun into little threads and made into little wires.
• So these can be used be in the same way as steel.
• These can be used in place of steel bolts and steel rods.
• Small cracks in the screws, sheets and rods can be easily treated. The spider can be allowed to spin its web on the cracked part. Since the web is as hard as the steel itself replacing the part is not necessary now.
• Just like that of the silk worm, the silk from the spider can also be artificially made.
• Then we can use these silk to construct even bridges and tunnels as the strength of the spider's web is much greater than that of the steel.

Drawback.

       The web of the spider is sticky in nature. Till now we didn't find out a substance which would remove the sticky nature of this web. So till then it will be dream coming true.........

From the beginning of my day, the water around always fascinated me. I would look at those animals taking a swim in those cool waters. I would long to swim like them. I didn't know the reason why I always drowned in those water. Even I cursed it not knowing the reason.

But when I knew the reason I tried to master that which prevented me from playing in water as on land.

Now when my mind started to solve the riddle an idea struck my mind

Whats my great idea by the way????

Its very simple. The idea revolves around the ship floating on water. Did you ever think why the ship with such a heavy load doesn't sink in the ocean.

 An object in a fluid experiences an upward force equal to the weight of the fluid displaced by the object. So if a boat weighs 1,000 pounds (or kilograms), it will sink into the water until it has displaced 1,000 pounds (or kilograms) of water. Provided that the boat displaces 1,000 pounds of water before the whole thing is submerged, the boat floats.

Because of buoyancy, even though the steel of the ship weighs a lot more then water, the ship also has a lot of air in it (the ship is not a solid chuck of steel), the lightness of the air off sets the heaviness of the steel to allow it to float.

The same principal can be used to make ourselves stand on the water. The shoe that we wear can be made in such a way that it has air which will make us stand on the water. The same way a life jacket we wear keeps us to stay afloat on the water.

• The shoe has to be designed in such a way that it is big enough to hold the air inside it so as to make ourselves stand on the water.
• The contact area between the water and the shoe should also be less keeping the pressure into consideration
• The shoe should be light weight but should be hollow and porous so as to withstand the pressure and to make the buoyancy effective than the downward force pushing you down to drown.  

Now its time to enjoy the unlimited fun of walking on the water just as on land. The fun starts now. Roll on to the air filled shoes, jump on to the water, start your game!!!!

We must have heard many times some one saying - "There is a magic in the air". But we think, really is there a magic in the air???

Thinking of it I couldn't make up my mind that really is there a magic in the air???

Then I came across a well known idea of generating electricity from the air. But in real time scenerio is this thing possible?? Then a really good idea struck my mind and here it is before you now.

 Before going into my idea let me explain you the concept behind my idea.

HOW IT WORKS??

 A high voltage power source causes sparks to oscillate across the gap.

 Each visible spark is actually a series of small sparks, jumping rapidly back and forth (oscillating) between the terminals.

 The size of the metal plates attached to the spheres from which the sparks are produced controls the frequency of the sparks produced.

 A loop of wire held near the oscilating spark, had a spark jump acrooss the air gap between the ends of the wire whenever a spark jumped across the high voltage.

How did it produce?? Did anyone even think of that???

The induced spark depends on the gap between the coil.

MY IDEA:

• We can transmit electricity in the air removing the need of the transmission wires. We can transmit electromagnetic signals at the transmission station and receive at the receiver station and produce electricity.
• Wireless chargers can be made. The high voltage supply can be converted into desired frequency by adjusting the size of the spheres at the input. Then it can be transmitted and a receiver can have the coil of desired gap. In this way mobile chargers can be made.
• All appliances which needs wire to connect from the plug now can work wirelessly.
• The complex wiring system in the houses and buildings can be removed by having a single transmitting system from which many appliances can be connected wirelessly.

ADVANTAGES:

• The need for the wires will be reduced thus decreasing the pressure on our precious resources like copper.
• There will be no need of wires for plugging in the power supply.
• The charging is now mobile and the appliance can be moved anywhere around.

Now I feel that there is really a MAGIC in the air.........

The world around us is very complex from the birds chirping to the web of a spider which is stronger than the steel thread.

But I think that understanding ourselves is much more complex than understanding there rest.

From the smallest mechanism that takes place inside our body each and everything is well- coordinated.

What happens when we sense a danger?? Why do we remove our hand when we feel the excess of heat??  We all must be knowing the reason for "what" and "why" but very few know the reason for "how"......

Let me explain in short how it works....

                                

The region between the two neurons is not connected together........Then you must be wondering than how really does it work???

Since we are now interested in the physics part only let me explain in short. The neurons produce an in-built magnetic field which is induced when something has to be communicated with other parts of our body.

What happens in case of a accident??? The reason why we fear the most is loss of some of our body parts like limbs. What if we have an artificial limbs that works same as that of our own legs......GREAT.....isn't it????

HOW MY IDEA WILL WORK ???

• If the neurons are attached with field detecting device and if we attach those with the limbs than it can make great wonders........
• Since the whole mechanism of the neurons works on the magnetic and electric pulses, the material that connects the neurons detects the signal accordingly.
• When it detects the signal it can vary the movement according to the intensity and the duration of the pulses sent by the neurons.
• The non-contacting portion of the robotized limbs can be made by the materials used now to connect the limbs after operation.
• One part is connected to the neurons and the other to that which connects the neurons.
• The junction between the two is such that it will be able to receive even the smallest of the signals and work accordingly.

 ADVANTAGES:

• The need for the crutches can be removed.
• The now available mechanism is all manual based in which the most of the work is done by the person itself. And it is not fully automatic.
• This artificial system is fully automatic and is line with the functions of our body. So it doesnt seem to be an external part of our body.
• This is also stronger than the real one. So in case of accident there is no loss of blood.

 DISADVANTAGES:

• Since this method involves connecting each and every neuron, it makes the process very tedious.
• The persons expert in this field will be hard to find because it is a complex mechanism and training in this field is hard.
• The cost will be obviously enormous as the specifications needed to meet the operation is high.

If it is practically implemented, then it would be a miracle for those who lost their body parts in the accidents............Wonders for the crippled and.........an achievement in the field of medical surgery....

 Who likes to stand in the hot burning sun???

We usually move under a tree or a shade. The temperature is considerably cooler even if  the difference in distance is very less.

 Did you ever stand in-between the doors such that you are half outside and half inside??

Try this you will notice something very peculiar. The temperature difference you will feel will push your mind to think something ahead. The same thing happened to me to think a bit away.

What if we can produce energy from this temperature difference??? We know the things but find it difficult to put it in a piece.  We usually heard of thermistors. But what really is a thermistor??

I will give a brief idea of how it works??

Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals. The temperature response is also different; RTDs are useful over larger temperature ranges, while thermistors typically achieve a higher precision within a limited temperature range, typically −90 °C to 130 °C.

We know this that change due to temperature can produce a potential drop across thermistor and eventually producing current.

APPLICATIONS:

•  This can be used in the western countries where the temperature difference between the outside and inside has a huge difference.
• A thermistor can be installed in the railway station in western countries as the temperature difference is huge. The outside temperature outside can go down below zero whereas the temperature inside is ambient. This difference can produce electricity.
• Nations which have extremely high temperatures can also use this method to produce electricity. The condition over here is straight opposite to the above example. The outside is hotter than inside. So there is possibility of producing electricity here too.
• Even in industries where temperature difference is huge.
• Coal mines and nuclear cooling stations are few of the examples where this is used.

ADVANTAGES:

• Its a clean form of energy that does not cause any harm to the environment.
• The installation cost is also not much as compared to other sources of energy.
• The maintenance cost is also very low.  

DRAWBACKS:

•  The temperature difference has to be sufficiently high so has to produce significant amount of energy.
•  This is not a constant source of energy. So one cannot wholly depend on it for all practical purpose.
• This method can only be a part and not the whole of the source totally available form of usuable energy.
• Since it is temperature dependent a small variation in temperature can cause huge difference in energy. This may lead to internal circuit problems.

 Many see that when we press or put pressure on some thing the shape of a thing changes. What if we produce electricity from the pressure that we apply on that object???

That will be really great....isn't it???

But how can we produce this electricity from this pressure??? Here simple peizo device comes into play. Before we go into detail, let us be clear what really does a piezo do??

HOW DOES IT WORK ?

The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry.

Whenever you apply a pressure on the piezo electric crystal than it converts it to elecrtricity.

The whole idea revolves around this. So when you apply a large pressure or apply pressure to a large no. of piezos together then we will get electricity.

APPLICATIONS :

•  For street lightning in the night piezos can be used. Piezos can be inserted in a part of a road say a patch which then is stored in batteries nearby. It will be best suited when it is installed at traffic signals as the vechicles halt for some time. when vehicles halt the pressure due to them produces electricity.
• It can be installed under some heavy objects in the room say cupboards where you get some constant pressure. Then this electricity can be collected in total to light the house.
• Motorised wheel chair can also make use of this principal.Since the person usually sits on the wheel chair the piezos can be inserted under the seat. This electricity can drive the motor.
• The piezos can be inserted under the chasis of a car. This also has a constant pressure. The electricity produced from it can be used to power the car.
• The piezos can also be inserted on the floors of the big malls or hospitals where you find many people moving in or out. So when they step in on that the electricity is produced from it.

ADVANTAGES:

• No pollution to the environment when producing electricity.
• It produces as high as 20kV of voltage which can be converted into usable forms of energy.

DRAWBACKS :

•  The total cost of installation is obviously high compared to the current methods available.
• They produce stary currents which is very dangerous. They can pick stray voltages in connecting wires connecting them.
• They are proned to cracking when the pressure exceed its limit.

 What if the energy we use doesn't exhaust at all??

What if the energy we use is again converted to a usable form???

That would be a miracle.....isn't it??

But this thing is not impossible.....as nothing in this world is impossible!!!!

A crazy idea it may seem but it is possible even practically. The whole idea revolves around converting rotational energy into some form of usable energy.

For this you need to know the working of dynamo.

It works on the principal of Faraday's laws of induction. The Permanent magnet is rotated between the coils which produces electricity. This idea can be carried forward in the practical applications too.

Let me explain my whole idea using an example.

Suppose we connect the dynamo to a running fan, what will happen???

It is as simple as that. The dynamo connected to it will produce electricity. What if we connect this current to the fan itself. Energy it uses is again given to it. The energy is used at its utmost level.

So we need to supply a minimum current to run the fan.

APPLICATIONS:

•  This thing can be implemented in the wheels of any vehicle. When the wheel rotates the dynamo too rotates. This energy can be used to power the vehicle again.
• The small wind mill like structure can be constructed at the top of the moving trains so that the wind pushes the blades of the wind mill when it moves. This in turn produces energy which can be utilized for powering the lifts and fans inside a moving trains.
• We can attach the dynamo in the wheels of the trains, maybe a big one connected to many wheels. This in turn produces energy which can be utilized optimally.

DRAWBACKS:

•  We know that practically no device or instrument has 100% efficiency. So energy converted by the dynamo is not 100%.
• While including the dynamo in the circuitry, other forces too act. The main opposing force is friction. Eventually this makes energy consumed for rotation without dynamo lesser than with dynamo.
•  The net energy produced is very less.

CONCLUSION:

•  If we reduce the frictional forces and improve the efficiency of the dynamo we can achieve a desired level of energy that we need to operate the system.

 The day is not far when this comes to existence!!!!!

Have you ever wondered what will happen to this planet when the electricity goes off........??

We are not able to tolerate even if the electricity goes off for a second!! Where from we get this energy which is always in high demand and for which the demand is increasing rapidly. Sources are many but feasibility comes to the account always. The renewable source is the best option for producing the electricity but when it comes to the supply the larger section of people it usually fails.

 Let me give you an idea what if we convert the solar energy at the outer space itself where it is available round the clock and send it to earth!!

First thing that comes to your mind is ....Is it possible???

Second thing strikes you is .....Is that feasible???

The main task lies in this, that How we are going to transmit it to the earth??

For me Here two ways are feasible .

·         Using microwave

·         Using laser

But How does it will work by the way?

Huge solar collectors will be used to collect the radiated energy from the sun.

USING MICROWAVE

• The energy converted by the photo voltaic cells are then converted into microwaves & transmitted to the earth
• The receivers can be orbiting or stationary on the earth.
• They collect the Microwave energy and then convert them into the form suitable for our use.
• The main drawback is that the microwave spreads for a large distance before reaching the earth.
• The intensity is reduced so we need to use large collectors at receiver's side.

USING LASER

• The above drawback can be overcomed in this method.
• The deviation in the LASER beam is very less & is within centimetres.
• The disadvantage of this method is that the laser beam is deflected by the clouds. So if the place is covered by clouds then it can not be transmitted at that place.

ADVANTAGES:

• They do not produce green house gases & also since they are away from earth they do not pollute the environment.
• If the initial cost are met it is the best alternative.
• They're not constrained by night/day cycles, the weather, or the changing seasons. And indeed, they would be much more efficient than any kind of ground-based station.
• The collection of solar energy in space is seven times greater per unit area than on the surface of the planet. Moreover, the amount of solar energy available up there is staggering — on the order of billions of times greater than what we draw today; the Earth receives only one part in 2.3 billion of the Sun's output. The potential for scalability is enormous, to say the least.
