What is wireless cell phone charger and wireless electric power technology?

A British company called Splashpower has also designed a wireless to be connected directly to phones and MP3 players. These chargers are based on electromagnetic induction, the same process used to recharge electric toothbrushes. One of the founders of Splash power, James Hay, said the MIT research "is clearly at an early stage," but it will be "interesting in the future."

"Consumers want a simple universal solution that frees them from the hassle of chargers and adapters connected to the wall," he said. But he added that the energy transfer is only part of the solution.

"We also should pay attention to another set of issues, in order to ensure efficient conversion of energy into a form that serves to feed the teams," he said.

Wireless power transmission is a technique that allows the distribution of electrical energy without using support material. Nikola Tesla was developed in 1891 and is known as the Tesla effect (named after him), consists of variations in magnetic flux, has the capacity to transmit electricity without the need to distance any means, either solid or some kind driver. Among the applications is the possibility of feeding places of difficult access.
The waves are transmitted through space, needing a connector and a receiver. Unlike data transmission, performance is the criterion to maximize, and will determine the differences between the main technologies.
