Imagine this one day you would be able to recharge your laptops and cell phones without plugging them into a socket. Well,  now that day may not be very far away..

Nokia, has taken its first small step towards it. They have  invented a prototype of a cell phone that recharges itself. It harvests ambient radio waves from the air, and turns that energy into usable power.

Traditionally wireless power systems are specifically designed with a transmitter and receiver in mind. The wireless waves  from the TV, radio and other mobile phone systems bounces around and most of it is wasted, absorbed or scattered .

Nokia’s prototype cell phone is designed to pick up all these waves and uses the collected electromagnetic energy to create electrical current, then uses that to recharge the phone’s battery. A huge range of frequencies can be utilized by the system.

The electromagnetic energy , would be enough to keep a cell phone from dying out completely .  Currently Nokia is able to harvest just 5 milliwatts from the air, they intend to increase it to 20 milliwatts first and then to 50 milliwatts. This would be enough to keep the phone alive during an active call, but it can slowly recharge the cell phone battery when it is in standby mode.

Nokia hopes to commercialize this technology in the next five years..

We all are definitely  looking forward to it
