Solar Power system Connected to Grid How it works ? Ø   Solar Grid-Tied systems use PV panels to generate DC power.  The DC power goes to a grid interactive (grid-tied) inverter which converts the PV panel DC power to 240 volt AC power that is compatible with the power grid.  The power from the PV panels goes (via the grid tie inverter) to supply the household power needs.  Ø   If the PV system is generating more power than the house can use, the excess is sent out over the grid to supply others.  If the house needs more power than the PV system can supply, then the extra is drawn from the grid as usual. Ø   Grid tied systems only work when the grid is up.  If the grid power goes out, the grid tie inverter is required to shut down immediately. Solar Power system with Battery Backup How it Works ? Ø   Off-Grid systems are independent of the utility power grid.  They generate electricity, store it, and...

Water is the source of life for all being on earth. Every living being depend upon water and they are made up of water. What is water ? Well this is technical characteristic of it is as follows. Density : 1,000 kg/m³ Molar mass: 18.01528 g/mol Melting point: 32°F (0°C) Formula: H2O If you look at the periodic table and locate tellurium (atomic number: 52), you find that the boiling points of hydrides decrease as molecule size decreases. So the hydride for tellurium: H2Te (hydrogen telluride)  has a boiling point of  -4°C . Moving up, the next hydride would be  H2Se (hydrogen selenide)  with a boiling point of  -42°C . One more up and you find that  H2S (hydrogen sulfide)  has a boiling point at  -62°C . The next hydride would be  H2O (WATER!) . And we all know that the boiling point of water is  100°C . So despite its  small  molecular weight, water has an incredibly  big...

 In 2014, a student from the Tohoku Gakuin University interviewed a number of taxi drivers in the town of Ishinomaki, in the Miyagi Prefecture of Japan, regarding any unusual experiences they may have had after the area was devastated by a tsunami on March 11, 2011. Yuka Kudo, who majored in sociology, presented her results the following year in her senior thesis. She asked the question of 100 different taxi drivers while they were waiting for fares. Most ignored her; some became angry; but seven of the drivers had some very unusual experiences they wanted to share.         The most noted account from her paper regarded a driver in his 50's who picked up a fare in the early summer of 2011. The driver stopped at the Ishinomaki Station to let a woman in her 30's -- who was wearing a winter coat -- climb into back of the cab. She asked to be driven to the Minamihama district of the city; he pointed out that the area was almost empty, and a...

When Dorothy Eady arrived to Egypt for the first time, it was obvious to her that she had been there before. But her last visit near the Nile may have taken place thousands of years earlier. Dorothy was born on January 16, 1904 in the London suburb of Blackhearth. Doctors believed that she would not survive a terrible fall when she was three years old. However, it seems that the accident she faced was the beginning of her unbelievable life - a moment of opening the gate to the memories of a past life. Over the years, many skeptics tried to disprove Eady’s mystifying tale, but nobody could ever fully negate that she was one of pharaoh Seti I’s (c. 1290 - 1279 BC) lovers. An Ancient King’s Lover? Dorothy grew up in a Christian family and she attended church regularly when she was young. One day, her parents took her to the British Museum. While looking at the photograph of the temple of Seti I, a pharaoh of the 19th dynasty of the New Kingdom Period (and the father of Rameses ...

Most governments throughout the world are short sighted in term of devising a policy and so their goals and targets are short term goals. The polices needs to undergo a considerable change and my idea towards it is to bring in a 10 year plan. It may be a 10 year plan but it would definitely have short terms targets. I feel that the Policy should not be a 'trend' driven or market driven but a policy which is  helps in reduce the usage of fossil fuel on the long run. The policy should be focused on the betterment of the regional community and its surrounding environment than a general policy with a common goal. For example, I feel that if the government is ready to subsidize the System costs and help the budding renewable energy players and consumers to grow in developing countries, it will not only have a positive impact on the community(creating new jobs) but it will also bring in the awareness of energy conservation.  The policy should be framed in such a way that not o...

Advantages of having a Solar Powered Boat: 1.     By introducing Solar System into the fishing boat we could thus save the battery life by inducing float charging when the boat is at ideal state. Which in term will help the user to save the battery from ageing. 2.     Savings on Diesel fuel costs, thus, the diesel saved can be used to run the boat for long duration thus reducing the dependability on diesel.  3.     By Keeping the radio on all times and any worse case scenario can be avoided. 4.     Even if the battery gets affected, by adding a simple DC/AC converter, we can still use other devices directly from solar. 5.     Intelligent controller automatically allows the lights to switch ON/OFF on dusk-dawn if it's at pre-set mode. and indication helps the boat user to indentify the charge left in the battery and how many more hours he can run before he needs charging. Important Function: ...

I have always have this intriguing question, where was Jesus in his teens? I was brought up in a Pius Catholic Family, where my extended family has 3 nuns. I did my schooling in Don Bosco Institution and we had daily prayers, bible reading catechism classes everyday until my 12th Grade.   Through out my teen years, I always wondered and thought,"Ok this is my life as a teen, going out for movies with friends, trying my first beer, etc but what was Jesus Teen life would have been?, in those times".  I always had a difficulty in concentrating on doing a job and finishing it until the end and I thought did he face these hurdles as well ? where was he ? the last time reference of him was a temple at the age of 13 and thats about it ! How can Bible not give us enough information about him ?  Conspiracy theorist say, His teaching were all similar to that of Buddha's teaching !! Both espoused altruism, emphasizing that it is more blessed to g...

Most of us don't often think about Earth's magnetic field, but without it, humans and most other life would be unable to exist. Earth's magnetic field protects our planet from harsh radiation blasted out of the sun. It's essential to everything we think of as life on Earth. Scientists believe our magnetic field comes from the rotation of Earth's liquid iron core around a smaller, solid core (this is an effect called geodynamo). Bu t the solid core hasn't always existed. What was the magnetic field like back then? This question has been a mystery for years, but a recently published paper in the journal  Geophysical Research Letters  by scientist Peter Driscoll seems to point to an answer.  For most of history, the magnetic field has had two poles, north and south. Scientists have found proof of that in very old rocks that still show signs of the magnetic polarity of their times. The dipolarity of our planet seems to have remained consistent...

High in the skies over  Kazakhstan , space-age technology has revealed an ancient mystery on the ground. Satellite pictures of a remote and treeless northern steppe reveal colossal earthworks — geometric figures of squares, crosses, lines and rings the size of several football fields, recognizable only from the air and the oldest estimated at 8,000 years old. The largest, near a  Neolithic  settlement, is a giant square of 101 raised mounds, its opposite corners connected by a diagonal cross, covering more terrain than the Great Pyramid of Cheops. Another is a kind of three-limbed swastika, its arms ending in zigzags bent counterclockwise. Described last year at an archaeology conference in Istanbul as unique and previously unstudied, the earthworks, in the Turgai region of northern Kazakhstan, now number at least 260 — mounds, trenches and ramparts — arrayed in five basic shapes. Spotted on  Google Earth  in 2007 by a Kazakh economist and archaeology ...
