Trying hard to achieve a success in their technology, the companes are working day and night.
Powercast is the pioneer and leader of long-range, power-over-distance wireless charging technology using broadcasted RF energy (radio waves) converted into DC power. Since 2003, the company has provided solutions combining its FCC-approved transmitters and receiver chips to enable automatic, over-the-air charging of multiple devices – no charging mats or direct line of sight needed.
Continue to drive wireless charging innovation because we believe that, while the adoption of inductive charging is at an all-time high, the potential of this innovative technology is yet to be maximized.

Wi-Charge- Power is delivered using safe, focused, beams of invisible infrared light. http://www.wi-charge.com/technology/
some of the companies working on wireless energy transfer are:
- WiTricity
Resonant coupling occurs when the natural frequencies of the two systems – a source and a receiver — are approximately the same. WiTricity power sources and receiver devices are specially designed magnetic resonators that efficiently transfer power over large distances via the magnetic near-field.
- ubeam
wire-free charging technology that will transform the way consumers and industries charge and power electronic devices at home, in the office, in the car and beyond. WattUp is a revolutionary radio frequency (RF) based charging solution that delivers intelligent, scalable power via radio bands, similar to a Wi-Fi router. WattUp differs from older wireless charging systems in that it delivers power at a distance, to multiple devices – thus resulting in a wire-free experience that saves users from having to remember to plug in their devices.

Humavox Technology
ETERNA wireless charging platform utilizes near-field radio frequency (RF) resonance, combining active components and proprietary algorithms and applying it in a cavity with unique properties.
This results in the creation of a strong RF coupling path between the system’s transmitting (Tx) and receiving (Rx) elements.
Enabling highly efficient wireless power transfer to the device under charge, regardless of its placement, position and orientation within the cavity
