Why train is in this shape?


I am sitting in a strategic chair in my office. The advantage is, I can see all "shinkansens" entering, sleeping and exiting the Tokyo station from my chair. It is nice view - as approaching the station, they used to be in a very slow speed and my view is from 29th floor - it appears like a python moving on the ground. I have done little investigation about them and found that they are moving on wheels. Thus I started studying about the wheel technology and I was forced to learn that the biggest challenge in implementing a train running on wheels is the gravity and friction. When the gravity pulls the train down, the friction is getting powerful. Either we need to prevent gravity at the gate or kill friction on the track to achieve smooth running.

I was in the mud of wheel and shinkansen articles and realized that the "wheeled" shinkansen technology is stuck at achieving 500 Km/Hr speeds due to gravity and friction. That too after burning a lot of electricity or fossil fuel and contributing to global warming and sound pollution! Many scientists and engineers are still working to identify possible techniques to increase the speed further. (Oh! They ignored me! That is why this article! :-))

Thus, after googling for few minutes, I was able to summarize today's challenges as below:

  • Speed is limited at 500 Km/Hr
  • Heat and sound pollutions are a concern
  • An accident will end up in heavy damage including lot of life.
  • Needs lengthy platforms in the station caused scalability concerns.
  • Existing architecture uses a lot of complex mechanical designs making it very complex
  • Needs a very powerful engine adds up the cost of implementation

    I don't know why I am so intelligent to get such simple solutions for these complex issues within seconds! Trust me, it took only few minutes for me to solve all above issues!

    Here is my finding - the root cause for all above issues is due to the shape of train. Just change the shape of train and track; all issues are solved for ever!

    What shape? What is wrong with existing shape? uh... questions!

    Simple, change the shape of every car from 3D rectangle to sphere of same volume! Why sphere shape? Due to lot of advantages of sphere shape:

    - High tolerance - even if it hits hard, it retains the shape.
    - No Tires - makes design simple and movement flexible
    - Low friction - compared to any other shape, the energy required to move a sphere is very less.
    - High Mobility - due to its shape, it has an inborn tendency to ignore gravity/friction and keep moving
    - Low running cost - as friction is low and mobility is high, we save a lot on the daily energy requirements to start, run and stop a sphere.
    - Security – As sphere is having much higher tolerance than any other shape, the cars are resistant to damages caused by collision and accident.
    - Scalability - We can stack the cars vertically, one above other - saves length of platform. Bring the sphere one by one to the ground, board the passengers and push to the track!

    So what are we going to do? - we are going to replace every car in the train with a sphere. Inside the sphere, there will be a "floating" compartment where the seats are arranged. As it is floating, it doesn't matter whichever way the sphere turns, the passengers will retain the same position. So, now our train looks like a chain of spheres. Keep it in a track, don't connect any engine - just clap the hands and give a mild kick at the back - you will see that it started moving! This is sufficient for implementing a metro rail system - the station master can give a kick at the back of the train and it will reach the next station! No power, no engine, no electricity, no pollution....

    For high speed transportation, use the help of an engine. You may have to design a tunnel to hold the spheres in place. Put enough oil as lubricant to make system further smooth. In this setup, I am sure that even by using an auto-riksha engine, we can achieve the speed of more than 1000 Km/Hr - that is more that the speed of an international flight!

    So when you are going to implement this concept? ("Don't you agree with me?")

    Fish Electricity from Kitchen Waste


    Most of my articles are tend to be about electricity and the methods of producing electric power. This is not because I am an "electric man", but the society made me to dig on electricity. I can't keep my mouth shut when the society is starving and at the same time food is available under their nose! Even after reading all my articles, the ministers are repeating the same story - today they will say "we have to do load shedding" and tomorrow in another stage they will say "no...this year we have enough water in our government.....so no load shedding...". Now, Google is fed up with these statements and asking me what to do! They have already installed a dedicated server to handle these statements because the number of search results on electricity, load shedding and power cut is in millions! Can't trust? See it here and here!

    Aquariums are very beautiful and many of us own one and used to keep in our houses. It is an amusement for kids as well as elder people to feed the fishes. This is the story of simple houses - keeping fishes for non-profit purpose. There are farmers who does large level fish farming. Usually this is supported by government through various means such as subsidy, loans and marketing support. If you have enough land and water, this would be an ideal business for you - much better than software development or engineering. No certifications required no written tests, no job interviews!

    Time to start questions! "Dude... you started with Edison, electricity and power cut, and ended with fish farming... what is this? Do you think that we are fools?...." Different from previous articles, this time the questions looks little tough!

    Trust me, without a reasonable reason, I won't talk about anything. I used to see those simple facts where all the science community used to miss. This time also! Let us see what it is.

    We have severe concerns about the production and consumption of electricity because the demand is more than availability. No proper planning has been taken to manage the future demands of electricity. And the most disappointing fact is that, even if we plan, it will take years to start the construction. Even if the construction is started, again years are required to complete it and start the production. In short, we need a cost effective and quickly scalable technology for producing electricity. In addition to that, if the source is natural, there is nothing like that!

    Now, time to link this requirement with fish. Everyone knows that there are many fishes which can generate electricity from their body. The most powerful one out of these fish community is "electric eel". Read the article carefully - you will see that it can generate 500 Volts, 1 Ampere electricity. That means, just one fish can drive a 500 Watts pump set - which is sufficient to pump water for one small family! If you have just 5 numbers of such fishes, it is more than enough to run the complete house with all equipments such as TV, Washing Machine, Heater, Iron box, or even Air Conditioner!

    Now, the cost of production - these fishes can be trained to eat your kitchen waste and biological waste! This has two advantages - the kitchen waste can be converted to electricity as well as we can stop worrying about waste disposal and management - in other words, we don't have to take loan from ADB! Will have a positive impact on GDP!

    The implementation strategy can also be in two forms - either every house can feed their own fishes or a big fish farm can act as a "fish power station" for the entire state. The existing distribution infrastructure can be used in this scenario also, which helps in reducing the cost of implementation. To easy the management, it is a great idea to merge electricity department with fisheries department and assign a jobless minister to head it.

    The summary is:

  • Cheap electricity - prices will further go down and GDP will further go up!
  • plenty of electricity - no more load shedding!
  • Bio-Electricity - no heat, no radiation, no dam collapse, no toxins etc.
  • Electricity from kitchen garbage - better waste management
  • Fishes controls mosquito breeding - No more "Chicken Gunia" and "Dengue".
  • Can be integrated with existing aquariums or fish farms - seamless integration
  • Scalability - just grow more fishes to support growing demand
  • Quick production - Comparing to the current power projects which takes years to complete, it will take just few months only to get a fish productive.

    Now tell me, is there any reason to not to make use of it? ("Don't you agree with me?")
