Witricity is a technology that wirelessly transfers electrical energy between two objects without physical contact. It works by using a source resonator to induce an oscillating magnetic field at a specific frequency that powers a receiving device. Witricity has applications for consumer electronics, industrial uses, medical equipment, and the military as it provides a more convenient, reliable, and environmentally friendly way to power devices without cables or batteries that require replacement. However, witricity also has limitations such as not providing enough energy for large vehicles and equipment and potential issues with retrofitting existing technology or energy theft.

witricity
Witricity, also known as wireless power transmission, involves transmitting electric power through electromagnetic fields without wires. It was first proposed in 1889 by Nikola Tesla but recent advances by MIT engineers in 2007 have improved the efficiency. There are two main techniques: near-field uses induction coils to generate magnetic fields for power transfer over short distances; far-field uses microwaves or lasers to transmit power over longer ranges. Witricity has applications for wirelessly charging devices, electric vehicles, and powering devices like televisions without cables. While it provides advantages like eliminating wires and batteries, efficiency is still only around 40% and there are security concerns about energy theft.

Witricity is a technology that transfers electric power wirelessly through electromagnetic induction. It was first proposed in 1891 by Nikola Tesla but failed to gain traction until researchers at MIT successfully transmitted power wirelessly over short distances in 2007. There are three main types of wireless power transfer: inductive coupling for short ranges; resonant inductive coupling for mid ranges; and microwave transmission for long ranges. Witricity has applications for powering devices, charging electric vehicles, and industrial uses where wires present safety hazards. While it promises more convenient power delivery, challenges remain in standardizing frequencies, reducing power losses over distance, and addressing health and safety concerns with long range microwave transmission.

Wireless electricity
Wireless power transfer, known as WiTricity, involves transferring electric power over distances without wires. It was first proposed in 1891 by Nikola Tesla but efforts to commercialize the technology were halted due to issues with power loss, theft, and health concerns. In 2007, researchers at MIT were able to wirelessly transfer power between two coils over a distance of 2 meters with 43% efficiency. There are three main types of wireless power transfer: inductive coupling over short ranges; resonant inductive coupling over mid ranges; and microwave transmission over longer distances. Potential applications include wirelessly powering devices, automatically charging electric vehicles, and creating shock-free industrial environments. While it could make power delivery more convenient, challenges remain in

WiTricity - Electricity through Wireless Transmission
Wireless power transmission through resonance coupling was proposed over a century ago but recently rediscovered. It works by powering electromagnetic resonators at the same frequency so that energy transfers between their coupled magnetic fields, allowing devices to charge without wires. Researchers at MIT demonstrated this by lighting a bulb from a source over 2 meters away. Applications could include wirelessly powering devices, vehicles, and buildings to improve efficiency over transmission lines that incur large losses. While promising, wireless power systems require transmitters and receivers tuned to the same precise frequency for energy to transfer effectively over distances.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
