Wireless transmission is ideal in cases where instantaneous or continuous energy transfer is needed, but interconnecting wires are inconvenient, hazardous, or impossible. The tangle of cables and plugs needed to recharge today's electronic gadgets could soon be a thing of the past. The concept exploits century-old physics and could work over distances of many metres. Consumers desire a simple universal solution that frees them from the hassles of plug-in chargers and adaptors."Wireless power technology has the potential to deliver on all of these needs."However, transferring the power is the important part of the solution.

With wireless energy transfer, the efficiency is a more critical parameter and this creates important differences from the wireless data transmission technologies. To avoid the conflicts like recharging and carrying its appliances of electrical and electronic devices, wireless power transmission is desirable.

Wireless power transmission was originally proposed to avoid long distance electrical distribution based mainly on copper cables. This can be achieved by using microwave beams and the rectifying antenna, which can receive electromagnetic radiation and convert it efficiently to DC electricity. Researchers have developed several techniques for moving electricity over long distances without wires. Some exist only as theories or prototypes, but others are already in use. Magnetic resonance was found a promising means of electricity transfer because magnetic fields travel freely through air yet have little effect on the environment or, at the appropriate frequencies, on living beings and hence is a leading technology for developing witricity. In our present electricity generation system we waste more than half of its resources. Especially the transmission and distribution losses are the main concern of the present power technology. Much of…...

...Nowadays, the electricity exerts a significant influence on individual's life, not only because the high demand of production in each country, also the diversity of peoples' lives. Therefore, the raw materials, such as oil, coal and gas, are highly demanded in the world. Known to all, however, these materials which are mentioned above are non-renewable resources, and their reserves will certainly, continuously and greatly decrease, so, exactly it is vital to reverse the irrational use of non-renewable resources. In recent years, in virtue of the greatly decreasing of non-renewable resources, scientists and researchers are accelerating the development of the Green Energy, such as wind, wave and solar energy, strenuously making the new green energy more acceptable and popular among individuals, countries and the world. "For example, Renewable energy is seen by the UK government as one vital component of a climate change strategy, for which it has set a notional target of 10% of electricity production (Department of Trade and Industry, 1999)."( Citizen versus consumer: challenges in the UK green power market S.L. Batley, D. Colbourne, P.D. Fleming, P. Urwin). But, there are some critical problems which people cannot ignore, such as the green energies' exploration, technology, exploitation and prices. Consequently, how to explore and use the green energy, instead of the non-renewable energy, to the most degree and enable the green energy to be affordable to the public have become...

...DANGERS OF ELECTRICITY DANGERS OF ELECTRICITY What are the dangers of electricity? According to: Acceleratedstudynotes. (2012, 03 10). Danger of electricity. Retrieved from http://www.acceleratedstudynotes.com/2012/03/10/igcse-coordinated-science-dangers-of-electricity/ Dangers of Electricity contain a range of risks, which are Electric Shock, Psychological Damage, Physical Burns, Neurological Damage and Ventricular fibrillation resulting in death. If not properly controlled or harnessed, can result in serious danger to those who use it. The risks with electric power can be divided into two categories: direct and indirect. The direct danger is the damage that the power itself can do to the human body, such as enabling someone to breathe or regular heartbeats, or burns. The indirect dangers of electricity include the damages that can result to the human body like something caused by electric shock, an explosion, or a fire. Electricity at any voltage can be dangerous and should always be handled with caution. An electric shock can occur upon contact of a human or animal body with any source of voltage high enough to cause enough current flow through the muscles or nerves. Dangers of an over heating cable: Sometimes another danger can begin if an extreme current flows in the wires. They will heat up and the insulation can melt which will cause it to produce poisonous fumes or even catch fire. Therefore it is advice to avoid using appliances that draw......

...Electricity is important to life. A vast number of machines which are invented nowadays cannot be operated without it. As a matter of fact, electricity is used mostly in four main areas: industry, public health, media and transportation. First of all, electricity plays an integral part in industry. Thanks to the invention of electricity, a lot of equipment has been invented including computers, subways, bulbs,etc .... .Electricity is the crucial factor in operating most devices. As a matter of fact, we now lighten our lives with electricity, which is unexpensive and friendly-environment. Moreover, electricity has given birth to assembly line, which means everything is produced by machines precisely and constantly, saving us a great amount of time and money. Apparently, electricity is used by all walks of life everyday in all aspects. For example, in summer, air conditions are used to provide us with cool air and we turn on the heating system to keep the room warm in winter. In the second place, electricity is essential in daily transportation. Only with the advent of electricity can people create the traffic light. This is a great contribution to the safety of people on the street.

...Wireless Electricity What is it? The understanding that electricity could travel through the air has been around since Tesla. Frequencies have been used to transmit an electrical signal since the 1800’s and now the world is seeing the next level of the frequency evolution. The new standard in power is wireless and it has the ability to revolutionize nearly every industry that benefits from the use of power. Everything from a small toy to a large industrial air handler can be run without wires and instead be a standalone unit that never loses power. The basis of wireless power transfer occurs between a handful of phenomena that have been discovered by scientists recently. Magnetism is something that we have been exposed to since early in our lives. Electromagnetism we have always known to be magnets coupled with electricity makes the magnet stronger. Magnetic induction has been around since 1831, it was theorized by Michael Faraday to be the medium to induce current in a nearby circuit (BBC). Energy and power coupling is a virtual handshake between the sending and receiving units. There does not have to physical contact to deliver the power and this is where the science gets even more interesting. Resonance is a delivery method that isn’t new to us because we have been using it for centuries. It is a naturally occurring frequency that occurs when the system of kinetic energy interacts with potential energy (Witricity, NA). Resonant magnetic coupling can be considered......

Electricity

...------------------------------------------------- Electricity Lightning is one of the most dramatic effects of electricity. Electricity is a general term encompassing a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena, such as lightning, static electricity, and the flow of electrical current in an electrical wire. In addition, electricity encompasses less familiar concepts such as the electromagnetic field and electromagnetic induction. The word is from the New Latin ēlectricus, "amber-like"coined in the year 1600 from the Greek ήλεκτρον (electron) meaning amber(hardened plant resin), because static electricity effects were produced classically by rubbing amber. Usage In general usage, the word "electricity" adequately refers to a number of physical effects. In scientific usage, however, the term is vague, and these related, but distinct, concepts are better identified by more precise terms: * Electric charge: a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged matter is influenced by, and produces, electromagnetic fields. * Electric current: a movement or flow of electrically charged particles, typically measured in amperes. * Electric field: an influence produced by an electric charge on other charges in its vicinity. * Electric potential: the capacity of an electric field to do work on an electric charge,......

Electricity in Bangladesh

...Electricity is really just organized lightning but it is most powerful indicator of any country’s economy. The infrastructure for energy in Bangladesh is quite small though it has large natural gas resources and only 62% of the total population has access to the electricity. Summit Power is one of market leader along with Summit Power Ltd, BPL, BANGLA CAT, HOSAF Group. Private companies have limited capital also gas the companies have to import oil and coal from foreign country. Shortage of the raw material is not only threat of this industry, many company use second hand machines for production due to this action OTOBI had to pay the penalty of 84 cores Taka recently. This limited amount gas will run out eventually it is used as fuel for electricity generation and commercial energy of the country. The Government of Bangladesh (GOB) has taken initiative to set up power plants so that the country has sufficient electricity within 2016.

Wireless Power

...Over the next decade, the most vibrant Wireless Power Transmission (WPT) markets will involve the contactless charging of portable and mobile equipment, in particular consumer electronics and electric vehicles. Today, development teams worldwide are stretching the boundaries of physics using available components to create systems that are able to compete with the efficiencies of wired solutions while offering the conveniences of wire free connections. In the 1890's famous scientist and engineer Nikola Tesla dreamt of wireless transfer of power. He envisioned a world, in which all electricity is transferred wirelessly, but the idea was more or less abandoned and highly efficient copper cables became the basis for modern electricity infrastructure. Then, a few years ago, Marin Soljačić, an assistant professor of physics at MIT, was dragged out of bed by the insistent beeping of a cell phone. In his exhausted state, he wished the phone would just begin charging itself as soon as it was brought into the house. So, Soljačić started searching for ways to transmit power wirelessly. Soljačić found magnetic resonance a promising means of electricity transfer because magnetic fields travel freely through air yet have little effect on the environment or, at the appropriate frequencies, on living beings. Working with MIT physics professors John Joannopoulos and Peter Fisher and three students, he devised a simple setup that wirelessly powered a 60-watt light bulb. The MIT work has......
