Apparently Nokia has a cool and unique phone in the works that will be able to charge itself without any wires. The phone accomplishes this by harvesting radio waves found in the air and coverts that energy into power for the phone. Such waves are derived from a number of different places, including TVs, radios, computers, and other mobile phones.
Since this phone is still in the development process, it is currently only capable of havesting 5 mw (milliwatts) at a time, which is just not enough to make the phone efficient. Nokia hopes to increase that number to 20 mw in the near future, making it more practicable to the typical cell phone user. While this type of phone does not have any kind of scheduled release date, the hope is that it will be ready within the next 3-4 years.
