LATEST MECHANICAL ENGINEERING INNOVATION People have been looking for ways to extend the life of a battery, be it a AAA, AA or even the D-size. What we have here is the ONE=TWO Spring Battery. The design is quite self explanatory.The spring basically extracts every little bit of juice form the battery!

Photographer Michel Denis captured these amazing pictures on safari in Kenya. He was astounded by what he saw: "These brothers have been living together since they left their mother at about 18 months old, On the morning he saw them, they seemed not to be hungry, walking quickly but stopping sometimes to play together. 'At one point, they met a group of impala who ran away.. But one youngster was not quick enough and the brothers caught it easily'." Then extraordinary scenes followed; they just walked away without hurting him. Life is short... forgive quickly, love truly, laugh uncontrollably...and never regret anything that made you smile.

The incident occurred in the Indian state of Punjab. Two puppies fell into a well. Their mother ran near the well and started barking, and attracted the attention of the owner, who looked inside and to his surprise there was a king cobra at the bottom, which didn't pose any threat to the puppies. Moreover, the reptile, looked after the puppies, by not allowing them to cross to the other side, wher e they could possibly drown, when the well is filled with water. In general, they spent around 48 hours together at the bottom and in these 48 hours the cobra sat quietly next to them. When help finally arrived from the forest department, the cobra slithered to the other end of the well. The puppies were not injured at all and the reptile was immediately taken into the woods and was released into the wild. Even the most deadly and dangerous creatures on earth know what Co-existence and mutual assistance is. The human race is in this respect far behind, and this is our biggest drawback....

On Marco Island, Florida a group of dolphins came to the aid of a lost Dog that had fallen into a canal and couldn't get out. The dolphins made so much noise, it attracted the attention of people living nearby, who then rescued the dog. The Dog was believed to have spent 15 hours in the canal water before he was pulled out by fire personnel and reunited with  his owner. One of the people whose attention was captured by the noisy, demonstrative dolphins said, "They were really putting up a ruckus, almost beaching themselves on the sandbar over there. If it wasn't for the dolphin, I would have never seen the dog.” (Source: ABC7news) He said also if the dolphins hadn't persisted enough to get their attention, they dog would have died in the canal. The dog had fallen over the edge of a concrete wall down into the water far enough that it had no chance of getting back up by itself. The dog was exhausted from being in the cold water for hours, and most likely suffering fr...

KFC has been a part of American traditions  for many years. Many people, day in and  day out, eat at KFC religiously. Do they  really know what they are eating? During a re cent study of KFC done at the University of New Hampshire, they found some very upsetting facts. First of all, has anybody noticed that just recently, the company has changed their name? Kentucky Fried Chicken has become KFC. Does anybody know why? We thought the real reason was because of the "FRIED" food issue. IT'S NOT!! The reason why they call it KFC is because they can not use the word chicken anymore. Why? KFC does not use real chickens. They actually use genetically manipulated organisms. These so called "chickens" are kept alive by tubes inserted into their bodies to pump blood and nutrients throughout their structure. They have no beaks, no feathers, and no feet. Their bone structure is dramatically shrunk...

Recently, one human rights advocate recorded allegation of doctors eating dead fetus after performing abortions at Shenzhen hospitals. To confirm the allegation, an undercover reporter from Eastern Express visited a state owned health center for women and children and asked a female doctor for a fetus. The doctor said that the hospital was out of stock but reminded the reporter to come back. When  the reporter went back to the hospital, the doctor offered ten fetuses for free. In another state-run hospital in Shenzhen, a nurse said that fetuses were in short supply and the price could go up from $10 to $20. In another clinic, one doctor offered the reporter a full-term fetus and recommended that it had the best healing ingredients. The disturbing human rights abuse comes from a distorted view of unborn children in Chinese culture. Traditionally, ancient Chinese considered ingestion of firstborns, aborted fetuses and placentas as part of a mother’s flesh. An unborn child has no p...

Biography of Sadi Carno t: (An inspiration for every mechanical engineering student) The applications of the laws of thermodynamics has led to the discovery of important machines like automobile, ships, airplanes , refrigerator, air-conditioner, etc. A young man, Nicholas Leonard Sadi Carnot of 36 years of age is considered to be the father of thermodynamics. It is emotional for many of us to know that inventor of an important field of thermodynamics was a boyish scientist who died at the young age of a mere 36 years. Sadi Carnot is a shining example for the young generation for it was his hard work and inventions which has lead to the design, developments and manufacture of present day automobiles. Personally, when I remember the contributions of this boy, I get goosebumps. Had he lived little longer, I’m sure he would have been involved in many greater inventions. Though lots of research has been carried out in the field of thermodynamics, the works of Sadi Carnot are considered ...

Years pass by and our kidneys are filtering the blood by removing salt, poison and any unwanted entering our body. With time, the salt accumulates and this needs to undergo cleaning treatments and how are we going to overcome this? It is very easy, first take a bunch of parsley or Cilantro ( Coriander Leaves ) and wash it clean Then cut it in small pieces and put it in a pot and pour clean water and boil it for ten minutes and let it cool down and then filter it and pour in a clean bottle and keep it inside refrigerator to cool. Drink one glass daily and you will notice all salt and other accumulated poison coming out of your kidney by urination also you will be able to notice the difference which you never felt before. Parsley (Cilantro) is known as best cleaning treatment for kidneys and it is natural!

There are thousands of temples all over India in different size, shape and locations but not all of them are considered to be built the Vedic way. Generally, a temple should be located at a place where earth's magnetic wave path passes through densely. It can be in the outskirts of a town/village or city, or in middle of the dwelling place, or on a hilltop. The essence of visiting a temple is discussed here. Now, these temples are located strategically at a place where the positive energy is abundantly available from the magnetic and electric wave distributions of north/south pole thrust. The main idol is placed in the core center of the temple, known as "*Garbhagriha*" or *Moolasthanam*. In fact, the temple structure is built after the idol has been placed. This *Moolasthanam* is where earth’s magnetic waves are found to be maximum. We know that there are some copper plates, inscribed with Vedic scripts, buried beneath the Main Idol. What are they really? No, they ar...
