Nokia’s Self Charging Phone Harvests Ambient RF
By
The folks over at Nokia now have a prototype cell phone that will make good use of the ambient RF energy from various sources to charge to power the phone. The concept is based off of work done by Nikola Tesla many years ago.
The system collects energy from ambient radio waves emitted by antennas, TV masts, Wi-Fi transmitters, and the like. This might all sound uber-scientific, but we’ve been using this technology for years. Have you ever exited a store, only to hear the beep, beep, beep of an accusing alarm system? Many retailers use radio frequency identification to prevent theft and track inventory. Like RFID tags, the Nokia phones would catch radio waves across a range of frequencies, harnessing them for power.
