Solar Power Applications...

Solar power is the conversion of sunlight to electricity. Sunlight can be converted directly into electricity using photovoltaics (PV), or indirectly with concentrating solar power (CSP), which normally focuses the sun's energy to boil water which is then used to provide power, and technologies such as the Stirling engine dishes which use a Stirling cycle engine to power a generator. Photovoltaics were initially used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array.

Solar power plants can face high installation costs, although this has been decreasing due to the learning curve. Developing countries have started to build solar power plants, replacing other sources of energy generation.
Since solar radiation is intermittent, solar power generation is usually combined either with storage or other energy sources to provide continuous power, although for small distributed producer/consumers, net metering makes this transparent to the consumer. On a slightly larger scale, in Germany, a combined power plant has been demonstrated, using a mix of wind, biomass, hydro-, and solar power generation, resulting in 100% renewable energy.


SOLAR ENERGY .. : :

1. Availability: The main feature of solar energy is it is available in abundance and throughout the day time. The area of availability is so huge that it can be tamed from anywhere and everywhere.

2. Cost: It is totally free and no one is going to charge you for using solar energy. So you can design all appliances in your home powered by solar energy, saving your hard earned money. In fact, if you do so, any government will appreciate it and fund you for your future projects.

3. solar-furnace Pollution and Remains: All fuels which we currently use leave behind combustion products which pollute and cause harm to the environment. Example, whether it is coal or oil, it has combustion products (soot) and other gases which pollute the environment. When solar energy is tamed, there are actually no combustion happening, thus no pollution.

4. Price: Depending upon the market, oil prices may vary. But solar power generation and utility does not depend on market variations.

5. Machinery and Maintenance: There is no machinery involved in the generation of electricity and power. Thus there are fewer maintenance problems and breakdowns. No spare parts cost as in case of generators.

6. Remote Utility: The availability of solar power anywhere and everywhere makes it possible to generate electricity even in remote locations where power cables cannot reach or the amount of power available is inadequate. You can set up your own generating station and live comfortably.

7. Renewable: Unlike fossil fuels, the usage of solar power causes no depletion in its availability. It is totally renewable for all practical purposes.

8. No greenhouse gas emissions and this clean source of energy making it possible to claim as one of the energy sources for the future.

9. Noise and other hazards: The generation of power from solar energy is a quiet operation and does not require huge population to take care of it. There are no hazards to the environment and the people when solar energy is used.

10. Lesser running cost and zero health hazards.

11. Government Grants: Local Governments and NGO’s are granting funds for those who use and implement new solar powered domestic appliances. Some of the organizations offer financial help for the students to carry out research on usage and taming of solar power for the daily requirements.


Few Drawbacks..::

1. People don’t encourage or come forward to use it as the initial installation cost is so high that it makes sense for them to use domestic power from the power plants.
2. The cost of the solar panels is too high and it occupies more space for generation of small amount of power, which typically can be interpreted as the power/space ratio being too high.
3. solar house During night time, since there is no sun light, you have to rely upon the domestic power supply.
4. If you want to make use of the solar power during night time, then you have to use a separate storage device to store the solar energy.
5. The power generation will reduce depending upon the amount of sunlight.
6. Also if the climate is cloudy or rainy or during winter season, then one cannot produce power from solar energy.
7. The installation on the roofs of your house may not be suitable with the angle of incidence of the sun light, thus making it less suitable for power generation.
8. The power generated may not be sufficient enough to support your entire domestic needs. Also this form of energy is not suitable for industries as the power demand is too high.
9. Solar power generation will not be effective in cold countries which are in high northern and southern latitudes.
10. Technically, D.C power is produced by the solar cells. For using it, this has to be converted into A.C before using it.

Even though the solar energy has too many disadvantages, they are being overcome by many new ideas and technical developments. Thus it is very important to develop a system of power generation from sunlight and optimize it before it is too late to save our Planet Earth.

MARINE ENGINEERING.

Hi friends.,

Let’s share some information regarding Marine Engineering career. , Interesting and exciting career at sea., if only you have a Passion towards it.

My Kind request is that “Come to Sea, only if you have a Passion.., not just to earn or since some of your relatives told to do a Marine course. If you join a Maritime course blindly, you may get bored if you didn’t like it. So think well before you do". And if you have made your decision clearly., then lets rock.

Basically one can do a four year Marine engineering course or Mechanical engineering and then one year up gradation course to become a Marine Engineer. Basic four STCW courses should be completed.

MEO exams plays an important role in the Marine Engineering career. Doing a four year Marine engineering degree will take you to sea., but surviving the sea depends on the individual. As a part of this., one has to pass the MEO exams from MMD(India) or from any other nations like (MCA, England or MPA, Singapore.)

First Part of the exams are MEO CLASS IV PART A ., One has to clear these exams before joining sea.., ie.. to join as a junior engineer on a ocean going ship. But, the education system in India is such that the candidates passing a certain Marine engineering Degree and after undergoing training in a Marine workshop is exempted from the Part A exams. Getting a proper Exemption Certificate from the MMD, he can sail as a Junior Engineer or Trainee Marine Engineer.

Then comes MEO CLASS IV PART B, to appear for this one has to sail as a Junior Engineer or TME for a period of minimum 180 days with 120 days of propulsion time. After completing the required sea time, the candidate can apply for CLASS IV PART B exams from the same MMD where he obtained CLASS IV PART A. He can also give exams from any other MMD in India provided that he has transferred his EXN-45 to that exam center. One can transfer the EXN-45 after clearing half the way in the exams. Say, after passing two functions from Chennai, he can also appear for other two functions from Kolkata or Cochin.

So, exams are flexible to the candidate and results are flexible to the examiner.. :-)

MEO Exams are easy when you are strong in the concepts with common sense, technical thinking and your dedication as a TME during your sailing.

So Friends., have a Happy and Safe Sailing .:-)

I will get back to you with more related posts.:-)
