THINK DIFFERENT

What is the similarity between Mahatma Gandhi, Rabindranath Tagore and Steve Jobs ,three men who brought great changes in their respective fields.

             
             
Mahatma Gandhi was a barrister he could have lived a life of comfort made millions but he choose to follow his heart and give up everything and work for the sake of Indians in South Africa and then against the oppressive foreign rule in India and thereby playing a vital role in achieving India's independence his thoughts and his work had tremendous impact across the people of the world , Albert Einstein on Gandhi's death said “The future generations would find it hard to believe that such a man existed in flesh and bones”.The journey of Mahatma Gandhi from an ordinary barrister to one of the greatest man in the history of the world comes from the fact that he was deeply spiritual and that he dedicated his life to selfless service of the people of the country without worrying about personal wealth which most people would think is a foolish thing to do.

         
                     Rabindranath Tagore also known a kaviguru which means the teacher of all the poets had a total dislike for formal school education and that he was a nature lover and loved being close to nature. He followed his heart into becoming the greatest poet,music composer, short story writer of Bengali language, his works are so powerful and profound that the songs composed by him are still extremely popular among Bengalis , he received his Nobel Prize for his work geetanjali infact the english translation of geetanjali one can just understand this fact that the difference between his translated and original work is like the difference between kissing a girls photo and kissing the girl herself. Now he is another person who chose to follow his heart and do what he loved to rather than go the beaten path.

               
 Steve Jobs dropped out of his collage as he did not see any value in the course that he was pursuing.With his friend Steve Wozniack started APPLE COMPUTERS the worlds first microcomputer company together they came out with Apple 1 and Apple 2 computers and later on after a visit to Xerox he saw the first rough example of a GUI taking a cue from that he designed the first GUI of the Macintosh Computer now the GUI made it much more possible for the lay user to use the computer. The GUI made computing accessible to ordinary people who did not find it comfortable to type commands and get things done by the computer and not only that the GUI added a new dimension to computing that is elegance everyone wanted to work on a screen with a beautiful Graphical User Interface , also it so happened that Jobs himself was fired from the company he started. After that he started two new companies one was Nexxt and the other one was Pixar, NexT developed the computer which was used by Tim Berners Lee as the first World Wide Web server at CERN. Pixar ended up being the most succesful animation company in the world. When the Operating System of Apple was getting outdated it acquired NexT and Steve Jobs came back to APPLE as the CEO, Steve Jobs put the company back in profit with the iMac computer. It was then followed by iPod ( a digital music player), iPhone and iPad thus Apple become one of the most successful technology products company in the world that changed and improved the way people used technology in their day to day lives.


The one thing common among all three of them is that they are the ones who did not follow the beaten track but followed their own heart and intuition all of them were free thinkers and innovated in their own way , they showed us that there is something called innervoice that one needs to listen to . There is something more in conciousness than just mere logical thinking.

Single Board Computers

     Ever since Raspberry Pi was made the board computers have become a rage with many such board computers coming into the market the latest being Parallela the $99 supercomputer that promises to change the way computing is done the single board computers are much cheaper powerful and will get more powerful in course of time as the processing power increases

The cheapest of them being Raspberry PI priced only at $35 and $25 is an open source hardware that runs on Linux operating system the aim of designing the Raspberry Pi was to teach programming to kids however enthusiasts are coming out with new uses of the pi its as powerful as a full fledged computer 10 years ago and does all the things of a that a full fledged computer does for an ordinary user. Thus this little computer can be an excellent computer for kids across the world especially in developing nations its an opensource hardware so can be copied and improved on . The two RPis consume 3.5 and 2.5 watts of electricity.
Raspberry PI


A Korean company HardKernal has come out with this little board computer Odroid U3 .  It is quite powerful and runs on a quadcore 1.7 Ghz Exynos processor and has 2 Gb of RAM the great plus point is it cost $59 and consumes very little electricity. Its quite powerful and small.
Odroid U3



The real power of computing when it comes to SOCs is brought by the Parallella board

Parallella has two Zynq-7000 series Dual core ARM A-9 CPU along with 16 or a 64 core Epiphany Multicore Accelarator  with 1Gb of RAM the most amazing thing about the small single board computer is that the 66 core version can actually deliver a processing power of 90GigaFLOPS consuming around 5 Watts of power . Now that's the performance of a very powerful computer that would cost someone thousands of dollars.


                So the above three are the examples of things that are going to come in the world of technology computers will be cheaper much faster and more affordable to everyone . This being Free Hardware would help engineers study, copy , modify and build better single board computers anywhere in the world.

           Also in all three computers the processors that are used are ARM RISC processors which consume far lesser electricity and are much cheaper than x86 processors made by Intel or AMD.

       These computers being cheaper will make computing a reality in many parts of world like South Asia,Africa and parts of South America.

Energy from underwater winds

Tidal energy using underwater kites to harness the energy of the ocean tides can be great solution to world energy problems when the issues of cost and effect of salty water on underground kites are effectively addressed. The video link below shows an example of how tidal energy works.

                   Water being far more denser than air the tides in sea and ocean would produce lot more energy per square meter as compared to wind . Also the scope of the utilization of this energy source can be huge as  most of the earth is all ocean ,however this energy would be generated only upto a few hundread kilometer distance from land and going too far away from the land would add to costs. Looking at this it makes us think why in hell we are burning coal, natural gases etc when there is immense energy available from the sun, wind,hydel and tidal energy why didn't we tap these sources of energy first.

        Here in this video you will find another example of how tidal power can be used for producing energy and mind you 100% clean energy.

      The unique feature of tidal energy is that it is the only source of energy that does not depend on the solar radiation for producing electricity. The tides in the ocean are produced by the gravitational effects of the sun and moon. This energy is enough to produce billions of watts of energy across the world.

         India would be highly benifitted by this source of energy since it has a very long costline and when we do have an honest and transparent govenrment  in place we can focus on R&D in this field and be totally free from using fossil fuels for energy needs, This would also save us from the pollution that may be produced when we use natural gas or coal for fuel.
