Nokia Developing Wireless Selfcharging Mobile

This article reports on how Nokia are developing a self-charging mobile phone that will use solar power together with the radiation emitted by phone masts. Obviously the device must be sensitive enough to pick up the 500Mhz to 10GHz range of frequencies and convert that into sufficient power to charge a phone. Current protoypes can only generate 5 milliwatts but the intention is to produce 10 times as much. To me the most worrying thing is the sheer amount of radiation that we are bombarded with every day. Sure wireless may provide a large degree of convenience, but due to the broadcast nature of the medium, it seems that a lot of energy gets wasted, let alone what all those radio waves are doing your insides.
