The Problem(s) I would love to solve as an engineer.

1. Traffic Problem in MetroPolitans:


As the problem of traffic is increasing day by day in metropolitans because increasing no of govt. Launched transports, I would like the government of my country to spend money in making running roads (kind of modernized trains only) instead of launching new metro trains, local trains, new BMTC, DTF, Volvo buses and etc which are enough bulky and large in size to occupy most of the part of road and causing traffic problems for normal private cars and taxis also.

As a civil and mechanical engineer, I would like to have a road partitioned something like below:




So now coming to the mechanism of running road I would like to have is:

1. It will be a kind of narrow train (1seater but can be made like duplex buses), let me name it as ‘Moving Train’. It will be running all the time continuously 24 x 7 hrs on all two –way highways.

2. There will be a bus code predefined for every bus stop. If a passenger wants to board this vehicle, he/she will enter that code at the appropriate bus stop (Source Stop) and driver of this moving train will get a signal that the passengers are there at bus stop with entered code.

3. Automated entrance and payment mechanism for passengers will be used. Computer Engineers can be of help there. At the entrance door of the moving train, an ATM kind of machine will be there, passenger is supposed to enter the code of his destination of bus stop, if he/she enters an invalid code, door will not open .If he/she enters a valid destination code, it will ask to swipe a pre-assigned and pre-paid kind of train pass (no cash money allowed) and appropriate amount of fare will be deducted from the passenger’s pre-paid account balance. If user do not swipe the card but enters the destination bus code, an alarm will keep on ringing until he/she swipes the card. In this way payment will be done and entrance door for user will open for entering into the train. Simultaneously entered destination code will be sent as a signal to the driver of the bus. There will be automated software that will sort the list of all entered codes till now. This will help the driver in giving priorities to the bus stops accordingly.

4. A passenger can board and get down from this train at appropriate stops only. No mid-ways stoppage will be allowed.

5. If the passenger gets his destination stop, a message will be spoken about the stop and door will get opened automatically and he/she can get down from it.

6. Security system in these trains: There may be chances of accidental fire or some other similar activities, in order to avoid such problems, these trains will be divided into bogies(just like normal trains) and each one of them will be fixed with hidden cameras(the one like IT companies use to monitor their employees). Headquarters will be there in cities that will be continuously monitoring this train for any terror related activities. Also if accidental fire is caught in one bogie, to avoid it to spread it to other bogie, a fire proof material should be used(If no such material exist till now, it should be made by engineers.)

7. If circles are there (having four different directions), in that case passengers need to get down from this train and should move into appropriate destined directions to cross the road and re-board the train of different direction.

So ultimately the use of constructing this kind of train will be people who are daily travellers and are mainly responsible for traffic can get benefits out of it. No more much time wastage in waiting for buses. No more overcrowded and over loaded bus scenes will be there. There will be less theft chances. Normal concrete roads can be used for private vehicles with normal traffic signals and traffic policeman.


2. Limited natural resources of Energy:

Natural resources and fossil fuels are getting depleted day by day; their resources are limited because they cannot be recycled back into the nature. They are the non-renewable resources of energy. In everyday life they are used to generate lot of energy. So as a chemical engineer I would like to make an artificial fuel with highest calorific value just like Hydrogen. Not necessary it should consist of only Hydrogen molecules, it can be of molecular formula like C[sub]x[/sub]H[sub]y[/sub]. Only focus will be to have its calorific value as high as Hydrogen and is not having drawbacks like Hydrogen has (dangerous explosive). I would prefer to make it by trapping CO[sub]2[/sub] and CO gases released in the atmosphere in the form of polluted gases. I would like to find out a mechanism or a chemical reaction for decomposing these gases into C and O elements
CO[sub]2[/sub] -> C + O[sub]2[/sub]
(This equation is not possible but this is the challenge to make something like this similar.)
If this approach does not work, I would like to find out some other mechanism of generating a chemical compound of molecular formula like C[sub]x[/sub]H[sub]y[/sub]O[sub]z[/sub](I will avoid Oxygen atoms though) having highest calorific value but no harm in assuming it also. I will try to use waste products from the daily life to generate this compound (or fuel) so as to make it cheapest also.
In this way people will not be affected by increasing prices of fuels.



3. Laziness in typing and reading:


While writing the article for this contest, I realised that there should be a low cost device, one easily available that converts what I speak into a text file and for making it multipurpose also I thought of putting an extra feature which will read a text file and speak up the text written in it. Software is available for this but for using them we need to buy them and should have a instant computer system also. I thought of having a device which does not necessarily require a computer when any thoughts are coming to my mind and can be of use for those illiterate peoples who don’t know how to read and write but want others to know their ideas in written. So to solve this problem as an Electronics and Computer Engineer, I would like to have a device looking somewhat similar to headsets with microphone also working on the mechanism similar to one used in modern mp3 players or i-pods (one which have memory space and can be inserted into USB port of our computer system having a software to make them compatible with computer system.). I will use the microphone of this device and whenever I will speak anything into it, a .mp3 file (or any other audio file will be generated by default) and a .txt file also by default. There will be a chip inside this device that will convert audio signals into letters (mechanism something like one used in talking alarms can be used). There will be one .txt file for every .mp3 file and will have same name as .mp3 file. Now coming to the reverse mechanism, same chip should read every letter in the .txt file and should generate a .mp3 file or it which will start playing itself when I switch on to headphones from microphones. A .txt file can be copied from the computer system.
