harging your mobile phone is a daily event for most people. You come home from work to find the battery sitting somewhere between 0 and 25% and plug it in to charge. Solar powered chargers and more efficient phones can extend the life of your battery, but inevitably you end up plugging it into a power point on a regular basis.

Nokia are trying to change that, however, by researching a new recharging system that would mean you never need to charge your phone again. Taking a lead from RFID systems Nokia are experimenting with harnessing the power from ambient radiowaves.

Those waves are always around us from the signals transmitted for TV, radio, and mobile phone transmissions, and can supply a tiny amount of power. Nokia intends to add a system to mobile phones that can grab lots of these ambient radiowaves producing enough power to sustain the phone’s battery.

In order to do that they need to generate around 50 milliwatts of power through the system. The current experiments being carried out at the Nokia Research Centre in Cambridge, England are managing 5 milliwatts. To maintain standby they need 20 milliwatts so that is the next goal, but 50 milliwatts is the true level they are aiming for.
