Haier’s wireless TV is not available in the market yet but it is an indication of what is coming. Televisions have already gotten ultra slim and can produce HD video without using very little space in your living room. However, TVs are still somewhat “wired” and you connect the DVD players, power cords and other cables although you could use some costly alternatives to reduce to the clutter to some extent. It is a good sign that manufacturers are coming up with electronics without cables.

Wireless Powered TV

The wireless power system was supplied to Haier was developed by Witricity. Power transfer is made possible through a coil on the back of the TV that receives power from another device plugged into a wall socket that resonates and the energy is transferred using a magnetic near field.

This TV also features Wireless Home Digital Interface (WHDI), which can stream 1080p content at 3 Gbps. It works at distances up to about 100 feet away. So there’s no need for video input cables either. The company did not provide a time-line for a consumer release. It appears it may take 6 months to an year before you can purchase it for your home.

This product was chosen to receive a 2010 CES “Product of the Future Award” from POPULAR SCIENCE.

Sony has developed a prototype power system that can send enough electricity to power a television set wirelessly over a short distance, it said Friday. In tests the company succeeded in sending a conventional 100 volt electricity supply over a distance of 50 centimeters to power a 22-inch LCD television.

Sony makes the point with data transfer rapidly becoming a wireless endeavour; demand for wireless power is also growing. Dell showed off its wireless charging dock last week, but the power has a very short distance to travel. What Sony is trying to do is another thing entirely.

There were no indications given about when this technology might make an appearance in the wild, but Sony attempted to whet appetites with this image of a claimed prototype. Sony hasn’t set a release date for gadgets containing the new technology, but it it expected to be released to the market in the next 6 months.

The system achieves this feat through magnetic resonance. A power supply feeds electricity into a square coil of wires 40 cm across, called the primary coil, to produce a magnetic field. When a secondary coil is brought within the magnetic field this causes a current to be induced and so the electricity transfer is completed
