In the effort to get away from our oil and coal dependency, nuclear energy is getting attention again. Here is an overview of nuclear energy.

An Overview of Nuclear Energy

Harnessing a chemical reaction at the nuclear level of certain materials produces nuclear energy. The process is known as nuclear fission.

Nuclear fission occurs when certain materials, such as uranium, are manipulated in a manner that causes them to decay quickly. A byproduct of this decal is immense amounts of heat. The heat is then typically used to turn turbines much as occurs in hydropower dams. The spinning turbines produce electricity, which is then used for commercial applications and propelling naval vessels such as submarines.

The largest known nuclear reaction can be seen everyday in the sky. The sun is essentially a nuclear reaction, but on a much larger scale than we could ever replicate. It does not blow up because of its immense gravity. It does, however, shoot off massive solar flares which contain more energy than we could use in years.

Nuclear energy is a popular subject with governments because it produces a lot of energy with relatively small resource requirements. Countries such as Russia, France and China have invested heavily in nuclear energy production. There are, however, significant problems with nuclear energy.

Nuclear fission is a fairly unstable process. Energy is produced by speeding up and slowing down the decay process. Essentially, it is a balancing act. Allow the decay to happen to quickly and your risk a meltdown. Although meltdowns are rare, they are absolutely devastating when they occur.

The best known nuclear disaster was Chernobyl in 1986. Located in the Ukraine, the individuals controlling the reactor attempted an ill-advised test. Blame has been put on the controllers and the basic design of the plant, but nobody is really sure as to the exact cause. What is known is control was lost and the nuclear fission went to fast. Huge steam explosions occurred followed by a full nuclear meltdown. A huge radioactive cloud escaped and dropped radioactive material over much of Eastern Europe. 330,000 people around the reactor had to be evacuated. Thousands died immediately. Hundreds of thousands, if not millions, of people have suffered health problems. Birth defects are a sad, regular occurrence. All and all, the meltdown produced 300 times the radioactive material produced in the two bombs dropped on Japan at the end of the Second World War.

Nuclear energy is a very efficient way to produce energy, but one that is extremely devastating when it goes wrong. All and all, we are better off finding another platform for our energy needs.

Nikola Tesla was born on July 9, 1856, in a very small village called Smiljan, in the province of Lika, Croatia. You may not know who this man is, but he invented the theories of electricity we use today.

Tesla finished his basic schooling in Croatia. He continued his education in the Polytechnic School in Graz and finished at University of Prague. He worked as an Electrical engineer in Germany, Hungary and France before coming to the United States in 1884 as an immigrant. When Tesla arrived in New York, he quickly obtained a job with Thomas Edison. Tesla worked for Edison for many years until finally there differences in methods separated the two men in 1885. There two main differences were that Edison believed that DC (Direct Current) was the power of the future. Tesla had been working on the AC (Alternating Current) power we have today. After the Tesla left Edison’s lab, George Westinghouse, founder of the Westinghouse Electric Company, bought patent rights to Tesla’s system of alternating-current.

There were many advantages to Tesla’s alternating current vs. Edison’s direct current. The advantages became prevalent when Westinghouse used Tesla’s Alternating current to light the World Columbian Exposition at Chicago in 1893. It was after this that people started to realize this type of electricity’s amazing abilities.

Tesla established a laboratory in New York City in 1887. His electrical experiments ranged from an exploration of electrical resonance and many studies of various lighting systems. In order to calm the public about the safety of Tesla’s power system, he would hold exhibitions of his power in his laboratory. He would light a light bulb without wires allowing the electricity to flow through his body in a spectacular flurry of lighting and sparks.

Tesla became a United States citizen in 1891. His creative powers were at its peak. He worked on and developed many things including the induction motor, new types of generators and transformers. He also developed a system that transmitted his AC current. There are so many things that you use today that Tesla created. It is little know but the lamp we use to conserve energy, the fluorescent light was also one of his inventions. Tesla had many interests in electrical power. Tesla best known for his method of a wireless power transmission. The Tesla Coil. He envisioned that he would transmit power straight through the air to the user for free. Amazing and truly a ground breaking idea. He started construction on a wireless power transmission tower in 1900. The project was abandoned due to his lack of financial support. Tesla soon turned his genius to other inventions, such as power generating turbines. He continued to have many problems with his financial support and many of his ideas were shelved.

Nikola Tesla is one of my favorite inventors. He had electricity flowing through his blood. The man invented so many things we take for granted today and received very little credit. He was well ahead of his time. We may thing that Edison was a great inventor and he was, but Edison and many others took Tesla’s ideas and exploited them to the things we have today for there own profit and took the credit themselves. We know now know this man was exploited and was not given credit where credit is due. Many Electrical Engineers still study Tesla’s notes in order to find an idea that can be exploited and elaborated today.

Tesla is most credited with His Tesla Coil. This coil will deliver power through the air with a great deal of voltage, like a lighting bolt. The wireless age is upon us, is Wireless power next?

“Before I put a sketch on paper, the whole idea is worked out mentally. In my mind I change the construction, make improvements, and even operate the device. Without ever having drawn a sketch I can give the measurements of all parts to workmen, and when completed all these parts will fit, just as certainly as though I had made the actual drawings. It is immaterial to me whether I run my machine in my mind or test it in my shop. The inventions I have conceived in this way have always worked. In thirty years there has not been a single exception. My first electric motor, the vacuum wireless light, my turbine engine and many other devices have all been developed in exactly this way.” Nikola Tesla

“Science is but a perversion of itself unless it has as its ultimate goal the betterment of humanity.” Nikola Tesla

Nikola Tesla died in New York on January 7, 1943. There is a lot of information on Nikola Tesla available. I have only touched on the tip of this mans genius. Take some time and look him up. You will be amazed!

The French Language

Roughly around 200 million people around the world speak French. This number includes people who speak French as a native language, as a second language and students of all ages who do not live in a francophone (French-speaking) country but have learned French. In fact French as a foreign language is the second most commonly taught language worldwide after English. It is also the only foreign language that can be useful throughout the world as well as in the United States. French comes in second after English on the list of the world’s 10 most influential languages. Proof of this is the pivotal role French holds. It is one of the official working languages in dozens of powerful international organisations such as the European Union (EU), United Nations (UN), World Health Organisation (WHO), World Trade Organisation (WTO), and a host of other worldwide institutions.

The French language of today is a direct result of long periods of evolution. France, throughout its long history, had been invaded by different ethnic tribal groups. The most distinguished of these are the Franks. They adopted the Latin being spoken at that time. Thus, the French language is a descendant from Latin. It is also known as one of the Romance languages which include Catalan, Italian, Spanish, and Portuguese. They are called such because their parent tongue Latin was the language of the Romans. Over the years, the early French language has undergone changes in words and grammatical structures. It has evolved into today’s global French.

Frenchspeak – Here, There and Everywhere

The French-speaking world spans the entire globe with its language heard in all the continents. Aside from English, French is the only language spoken as a native or first language on 5 continents.

In Europe, French is the official language of France, Luxembourg, Monaco, Belgium and Switzerland. France with a population of more than 60 million is one of the most modern countries in the world. It is one of the predominant leaders in the European Union. French is a co-official language in Switzerland. This picturesque country is one of the world’s richest countries. It is the centre of many international associations. Belgium, in the half past century, has emerged as a progressive European state. Brussels, the capital of Belgium, is home to the headquarters of the European Union and the North Atlantic Treaty Organisation (NATO).

In Africa, the French-speaking countries include Algeria, Burundi, Benin, Chad, Republic of Congo, Equatorial Guinea, Cameroon, Comoros. Cote d’Ivoire, Gabon, Burkina Faso, Central African Republic, Democratic Republic of Congo, Djibouti, Guinea, Madagascar, Morocco, Rwanda, Togo, Mali, Niger, Senegal, Tunisia, Mauritius, Reunion and Seychelles.

In the Americas and the Caribbean, French is spoken in Canada, Haiti, French Guiana, Martinique and Guadeloupe (these last three are French territories).

In Australia and the Pacifics, Vanuatu and the overseas French territories French Polynesia, New Caledonia and Wallis and Fortuna are French-speaking.

In many other countries, French plays a significant role either as an administrative, commercial or international language. Some of these countries are Andorra, Argentina, Brazil, Cambodia, Cape Verde, Egypt, Greece, India, Italy, Laos, Lebanon, Mauritania, Poland, Syria, Trinidad and Tobago, United Kingdom (Channel Islands), United States particularly Louisiana and New England, the Vatican City and Vietnam. Clearly, the French language is spoken everywhere.
