    Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible.  The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers

    What is WiTricity ? -WiTricity‚ stands for wireless electricity‚ is a term coined initially by Dave Gerding in 2005 and used by a MIT research team led by prof. Marin Soljačić in 2007‚ to describe the ability to provide electricity to remote objects without wires (wireless power transfer). This could be useful to power consumer and industrial electronics like cell phones‚ laptops‚ etc. -WiTricity‚ a portmanteau for "wireless electricity"‚ is a trademark of WiTricity corporation referring to their

    atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

    Energy transfers which take place in living organisms The nucleotide ATP (adenosine triphosphate) maintains both catabolic and anabolic reactions. Catabolic reactions e.g. respiration are where larger molecules are broken down into smaller ones with energy being released‚ and anabolic reactions e.g. photosynthesis are where smaller molecules are built up into larger ones which require energy. Catabolism provides the energy for organisms to synthesise larger molecules in its anabolic reactions.

    idea of wireless power transfer has been developed. In the early 20th century before the electrical wire grid Nikola Tesla shows much of his work on wireless power transmission. As revolution is taking place‚ and technology is getting more and more‚ the idea of power transmission is also changing. The demand of generation is changing. So keeping the demands in mind‚ the idea of wireless power transfer has been strived to develop in this project. Firstly this project involves the transfer of power

    one actuator system. Since most long-stroke movements are in a plane‚ this can be done by a contactless planar actuator. The topology proposed and tested in this paper provides long-stroke contact less energy transfer (CET) in a plane with only small changes in power transfer capability. 2.DESCRIPTION ACTUATOR Actuator is a mechanical device used for moving or controlling a mechanism or system. It converts electrical signals into motion. Here we are using a linear actuator;
