According to what was reported by Technology Review, Nokia would be working in the development of a technology that allows the cellphone to recharge themselves through radio waves in the surrounding environment. The electromagnetic radiation is around us daily from routers, Wi-Fi, TV antennae and cellphones.

In the Nokia projects, the energy on those waves could be converted into electricity useful enough to at least keep the cellphone battery constant. Markku Rouvala, one of the researchers from the Nokia Research Centre in Cambridge, has declared that his group is working on building a prototype that that is capable of retrieving 50 mW from the electromagnetic waves, necessary to recharge a cellphone, even if slowly. The main basis is the same from the RFID technologies, capable of converting an electromagnetic signal into an electrical signal, by using passive circuits.

However, experts say that a 50 mW goal is a little difficult at the moment, and most seem rather skeptical about it.
