Enemy 2

He doesn’t want to lose his confidence.

“Probably he will come after some time… May be today night… Let’s stay calm until he comes…”

“Common Rabesh… don’t lose your confidence… think positive… think positive “. He is mumbling himself.

He recalled what people told in “Idle time management” seminar that he attended recently.

“Generally, in office, some of the things that waste your time are Telephone calls, Extended Launch hours or Coffee Breaks, Junk Mails, Paperwork, Waiting-Delays etc.”

He smiled… No problem with any of these interruptions as of now. He has plenty of time. But, what to do?

He is remembering again the speaker words during that seminar.

“Idle brain is the devil’s workshop… we should never keep our brain idle, otherwise lot of junk thoughts will come in our mind. Those thoughts may change your life entirely. Keep yourself busy always”.

“I should not keep my brain idle”… just think what to do?

“What will happen to me, if I’m going be here for a week, or for a month? Will I become a mad man? Then if Vikram comes back, will I be normal? “.

“No… stop… stop thinking negatively… think… think positive”.

“Ok, Relax, Relax Rabesh, cool down… try to utilize this time…channel your thoughts in proper direction”

He became calm.

Then he decided to evaluate his design, so started analyzing if there are any flaws in it. He closed his eyes and remembered his whole design.

Now he can see his complete design in mind. He opened his eyes. He looked around to see if he can find something to draw on floor. He found a small chalk in corner.

He took it and commenced drawing his design on floor. He became a saint for some time and totally involved in drawing of his design.

One of his strength is his concentration. If he involved in his work, he forgets all circumstances and concentrates only in his work. He can’t even remember how much time he spends on it. He got that habit from his painting habit.

He was very good artist in painting. Usually he spends 4 to 5 hours continuously on his paintings. He left that habit because of his office work. Still somewhere in his heart, he feels pain as he left his most beloved habit.

He completed drawing design on floor. If management accepts this design then after a year it will be in the market.

His company is very desperate to release a product with minimum issues. Last year they released similar product, but that has many flaws, so it got many negatives reports. This time, they don’t want to repeat the same mistake.

They gave complete design of the new product responsibilities to him. His design is utmost crucial.

He is staring at his design on floor.

He is talking to himself by telling what the functionality of each module in his design is. After few hours, he found one design flaw. One major block is not interacting well with other modules in one scenario. Initially he ignored as that scenario is impossible to occur. But, now he realized that scenario can happen. If it happens, then product will fail.

He circled the place where that problem is there. Then he worked some time and adjusted design so that problem will not happen.

He kept on working to improve the design. Totally he found 10 flaws in his design. He rectified all those flaws and now, the design looks robust.

He satisfied now.

He understands the power of clam-ness and concentration. He never gets this kind of concentration at his office or at his home. Some or other kind of interruptions disturbs him a lot.

He once again thanked Vikram, if he is the person who kept him here.

It would be devastating if his previous design would have been in market.

He is very tired, and felt sleepy. Unknowingly he fell asleep.

He opened his eyes. He saw his apartment ceiling. He suddenly woke up, and turned his head around. That is his apartment bedroom and he is on his bed. He didn’t understand… confused for few seconds.

Is it dream? Am I dreaming that I’m in my apartment, or somebody kept me here?

He looked at his legs. There are no chains.

What is this? What happened really? Whatever that happened last night was dream? Or whatever is happening now is dream? His head heated with these thoughts.

“Beep … Beep …Beep…”

Some body is calling on his cellphone. He took it and looked at the caller. His manager is calling him.

He answered the call and said “Hello”.

“Hey… Rabesh. Good morning, sorry for disturbing you in early morning. I hope your final design is ready, so don’t forget to bring it today. I just call you to remind you, Ok”.

Rabesh is rubbing his head with his hand … so last night was dream.

“No, sorry, I’ve not completed it. I need to do few corrections, so I can submit it tomorrow”.

“What? Why? You said this can be done today? “

“Ya, but yesterday night I found few flaws in the design. I need to re-design few blocks”.

“Oh… It’s alright… We need the best design… that’s fine... Please work on it … but don’t forget to submit tomorrow”.

“Yes, certainly”.

He disconnected the call.

He got down from his bed and went to his drawing room.

His laptop is kept on table. He opened it and looked at the design. He sat on couch with laptop in relaxing manner and closed his eyes. He remembered what he did in his dream.

After few minutes he opened his eyes and re-worked on his design. After few hours he redesigned everything.

Now he looked at his design. It looked very solid.

He started writing an email to his manager, explaining his design, and putting some basic information about it and attached the final copy and sent it.

After sending that email, he remained calm for few minutes.

Then He sent a resignation email.

He realized those chains on his legs that he dreamt last night are nothing but his office responsibilities. Those are his real enemies. He was not able to move out of that small room because of those chains in his dream, and same thing is happening in his life. That room is his office cubicle, his office friend circle, his work and everything that is related to his office; this is not what he wants actually. He wants to utilize his creativity in drawings. So he decided to resign and concentrate further on his drawing or some other work where he feels happy.

Now he is relieved from those chains. He found a way to break them and get released from that small room. He is free man now. He can do whatever his heart wants to do.

He switched off his cell-phone, and packed everything to travel to some peaceful place.

After a year, a product based on his new design is released in market. Within few months that become huge success because of it’s easy of usage and robustness.

That company tried to contact Rabesh several times; however he refused to come back again. He did further study in paintings and settled in “God’s own country” Kerala. It didn’t take much time the world to recognize his talent. Later he became well known artist in painting. Most importantly he is very happy in his work and no more “chains” in his dreams again.

Wireless Power

I always thought that, we have so many apparatus in the present world wirelessly like wireless phone, wireless head-sets, wireless modem, wireless mike, wireless speakers etc. However why there is no solution or product yet available to transfer energy wirelessly.
Just imagine, how it would be, if you are able to charge your laptop, mobile phone, and modem without wires or at least lit your bulb wirelessly. The batteries in your laptop or mobile phone are some extent useful to make your device as a wireless in terms of power usage, but those are not real replacements. It is chaotic to see many power wires all over the house, it would be remarkable if we can avoid all those wires, and make the world a true wireless.
In a formal word, this technique is called “wireless energy transfer” or simply “wireless power”. This can be defined as “The transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors”.
But to my surprise, this is not a new topic; it is already done by the famous scientist Nikola Tesla in late 19th century. Nikola Tesla is a father of modern electricity. He is best known for his many revolutionary developments in the field of electromagnetism. His theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor.
He lit electric lamps wirelessly at both of the New York locations, providing evidence for the wireless power transmission.
However the million dollar question is, when wireless power was proven in late 19th century why still we are not able to use it? Why still we are using wires to transfer the power?
Before answering to this question, we first need to understand what actually Tesla proven during his experiment, which is called as a Tesla effect.
Tesla recognized during his experiments that electrical energy can be projected outward into space and detected by a receiving instrument in the general vicinity of the source without the need for any interconnecting wires. He went on to develop two theories related to these observations, which are:
a) By using two Tesla coil transmitter-receivers positioned at distant points on the Earth’s surface, it is possible to induce a flow of electrical current between them.
b) By incorporating a portion of the Earth as part of a powerful dual-elevated-terminal Tesla coil transmitter an electrical disturbance can be impressed upon the Earth and detected “at great distance, or even all over the surface of the globe.”
Tesla also made the assumption that the Earth is a charged body floating in space.
To prove his theory, he gave a mini scale demonstration. The wireless energy transmission effect involved the creation of an electric field between two metal plates, each being connected to one terminal of an induction coil’s secondary winding. A light-producing device was used as a means of detecting the presence of the transmitted energy. The light producing device is able to lite wirelessly.
After this experiment, Tesla decided to demonstrate this in larger scale and started designing the Wardenclyffe Tower, which is also called as the Tesla Tower. The main intention behind this tower was to demonstrate the transmission of power without interconnecting wires in a large scale.

This tower was designed to send transatlantic radio signals and provide power to nearby businesses without the use of copper lines; the 55 foot tower loomed ominously. The dream of Nicola Tesla to provide free power with no lines by harnessing the ionosphere would be demonstrated with this project.
The construction of this tower began on the land near Long Island Sound. This project had been funded by industrialists and other venture capitalists. The project was initially backed by the wealthy J. P. Morgan who had invested $150,000 in the facility.
Tesla's theory on how the tower would work was that, "By using two type-one sources positioned at distant points on the Earth’s surface, it is possible to induce a flow of electrical current between them." The inventor also believed that the earth was a charged source. His tower would work by combining these two principals and creating powerful disturbances in Earth's natural electric charge which could then be harnessed. The users of the power would receive it by burying one end of a wire in the ground, and then putting a large conductive sphere on their roof with another wire. One would serve as a negative power source, and the other positive. Tesla called it the "disturbed charge of ground and air method."
In June 1902 Tesla moved his laboratory operations from his Houston Street laboratory to Wardenclyffe. However in 1903, when the tower structure was near completion, it was still not yet functional due to last-minute design changes. After realizing Tesla had no plans to actually make any money from the project, J. P. Morgan stopped investing and encouraged other investors to shy away. By July 1904 Morgan and the other investors finally decided they would not provide any additional financing. In May 1905 Tesla's patents on alternating current motors and other methods of power transmission expired, halting royalty payments and causing a severe reduction of funding to the Wardenclyffe Tower. In an attempt to find alternative funding Tesla advertised the services of the Wardenclyffe facility but he met with little success.
By 1905, since Tesla could not find any more backers, most of the site's activity had to be shut down. In 1908, the property was foreclosed for the first time. Tesla procured a new mortgage from George C. Boldt, proprietor of the Waldorf-Astoria Hotel. The facility was partially abandoned around 1911, and the tower structure deteriorated.
In 1915, legal ownership of the Wardenclyffe property was transferred to George Boldt of the Waldorf-Astoria Hotel for a $20,000 debt. In September 1917 during World War I, the tower was blown up with dynamite on orders of the United States Government which feared German spies were using it. The failure of the project contributed a great deal to Tesla's eventual mental breakdown.
In that way the greatest invention by Tesla was ended without giving any benefits to common people. The success of Wardenclyffe would have changed the world and improved the planet a billion times over. It is not the case that the concept of “Wireless power” is completely abandoned. Few modern scientists are still doing experiments on it and trying to transmit the power wirelessly. Hopefully in future this will be possible and people can charge cell phones, PDAs, and laptops wirelessly. Until then we need to depend on wires. Oh! My laptop is showing low battery, I need to charge it, where is my power cable?

The Graveyard

It was dark and stormy night, Ravi was walking fast. He wanted to reach his village graveyard. He is one of the bravest boys in his village. He did many things to prove this bravery, however this time his friends asked him to put 3 cricket balls on any of the three graves at midnight, and next day they will verify it. Initially his friends thought he will refuse it, because of many rumors of that place like someone wearing white sari is wandering and killing people. Even adults don’t dare to go to that place in mid-night. But, Ravi didn’t listen.
After few minutes he reached the place, rain was pouring. He opened the gate…
“Keechhhhhhhhhhhhhh …..” it opened with a big noise.
His torch light stopped working suddenly. It helped him to see in dark, after that he was not able to see anything.
He stayed at the gate for few minutes… His eyes adjusted with dark ness.
Rain stopped, and only water splashes remain.
He slowly started walking inside…
He decided to put first cricket ball on grave that was near to the gate.
He approached the grave, and then he heard a sound…
“Hummmmm….Hummmm…” like someone was moaning.
He stared at the side from where that sound was coming.
He didn’t see anything, but the volume of the sound was increasing … and it was approaching him too…
“Hummmmm….Hummmm… Hummmmm….Hummmm…”
He frightened… whatever courage left, gone after hearing that sound.
He wanted to go back… But, he felt ashamed as friends would laugh.
He took deep breath… closed his eyes … the sound was coming close enough to him and going away as if someone was floating on air and making it.
“Common Ravi… you know there is no such thing called ghost” he was muttering himself. But, what was that sound…?
He approached the first grave and placed the cricket ball.
Then he almost ran to the second one…
Then he saw two red colored eyes … staring at him… he terrified…
He could not able to move for a second… His heart beat increased …
Those eyes were coming near to him …
He threw the ball on grave and started running away from that place…
Those eyes were following him in same speed ….
He increased his speed… running without looking back…
Suddenly he fall down by hitting something on the ground… then he looked back… no body was following him…
He darted his head… he didn’t see anything…
He approached the final grave... put the ball and tried to move away… but he couldn’t… He felt like someone was holding his leg from back…. One second his heart stopped beating…
He looked back… he saw a white cloth… that’s it… his heart stopped…
Next day… people realized that he died because of fear… the sound was because of a bird, two eyes were street dog… and holding him was just a nail … finally that was just a white cloth.
