Wireless power transmission for charging devices

Have you thought about charging your devices wirelessly? Yes, this can be brought to a reality and much effort is taken by the Disney Research for the same. They have designed a new technique for transmitting power wirelessly across a room in order to avail the users to charge their electronic devices as easily as it is to connect to a WiFi hotspot, thus abolishing the requirement of charging cradles or electrical cords.

The research team illustrated their technique, known as quasistatic cavity resonance, in a 16-by-16-foot room specially built at their laboratory. In the middle of the room was placed a copper pole and then a little gap was formed in the pole. Discrete capacitors were placed into the gap. They securely produced near-field standing magnetic waves that filled the inside of the room enabled powering the fans, lights, and cell phones concurrently.

In the present day, most of the wireless power transmission comes over very small distances, normally consisting of charging pads or stands. The quasistatic cavity resonance technique consists of producing the electrical currents in the metalized floor, ceiling and walls of a room. This enables the generation of uniform magnetic fields that fill the interior of the room, which, in turn, transmits power to the receiving coils that function at a similar resonant frequency as the magnetic field. The generated currents in the framework are guided via the discrete capacitors that segregate potentially unsafe electrical fields.

Though researchers have accomplished with their development and testing but every innovation in the technology comes with its pros and cons.

Do you think this method would be feasible to be used in our day-to-day life?
