Concept of charging gadgets using electromagnetic waves

Generally , there are two widely used modes of charging them. One is to use an AC adapter which delivers electric power to your gadgets. The other option is to use solar power, though it can be used only for certain devices which have a necessary level of compatibility. And with solar chargers, weather fluctuations can be the spoilsport.
So –

1. Apple Examines WiTricity Wireless Charging for Use in Next iPhone.
The future generation iPhone users can use WiTricity Wireless Charging to charge their devices. Most mobile devices could be charged using this technology if they are within the one meter limit of your computer. This new method of charging will eliminate the cables and batteries. WiTricity is attracting a lot of attention from the industry and media.

2. The phone of your dreams powered by renewable energy.
Industrial designer Alexander Mukomelov has conceptualized a handset named Magic Stone. The users of this handset can recharge it using solar power during daytime. Another striking feature of this concept is that when the sun isn't available, the user will be able to continuously recharge it using ambient electromagnetic waves.

3. Powering small electronic gadgets with ambient electromagnetic energy.
It is an entirely new technology as no one has been successful at this before. A new technology draws electromagnetic energy from surrounding sources like radio transmitters and mobile phone networks in order to charge new devices. It uses an antenna to capture the electromagnetic signals from other sources, and later convert it from Direct current to Alternating current to store in batteries and capacitors. The device is capable of exploiting another sources of energy when one frequency weakens. It will soon be available for consumers and could be used at places like Airports

4. Nokia's RF charging technology:
The company Nokia Research Cente is working on a prototype device that never needs power from a wall socket. The device sources all the power it needs from ambient radio waves. The cellphone will be able to convert electromagnetic radiations emitted from Wi-Fi transmitters, cellphone antennas, TV masts and other sources into usable electricity, which can recharge the phone's onboard battery.
