Eco Factor: Technology developed to convert residual power from Wi-Fi signal for electricity.

A new technology developed by RCA could end the woes of all those individuals who are often looking for ways to keep their cellphones buzzing. The company initially developed a technology as an emergency power supply, but little modifications could enable it to keep cellphones charger without ever being plugged in to the wall socket.

Dubbed AirPower, the system absorbs power from increasingly ubiquitous Wi-Fi signals. The first products will be the AirPower chargers, which are planned to be available by the holidays. These little devices will be able to convert residual power from any Wi-Fi signals to recharge its internal battery. Once charged, the device will be able to recharge conventional handheld devices.

The company explains that the AirPower system works by converting the 2.4GHz Wi-Fi signals into electricity, which can later be used to recharge portable electronic devices.

Eco Factor: Universal charger harvests solar energy to charge handheld devices.

MOSeco has unveiled its new ES905 universal charger that has been designed for all those, who’re always interested in a camping trip. The universal charger has been designed to harvest solar energy during the day to charge a wide range of portable electronic devices, including mobile phones and digital cameras.

With an LED flashlight to top everything up, the device costs about $83.

Crank Up Battery

Re-chargeable batteries are no good when they run out of power and you have no electric point handy to tank them up again. Here’s where the concept of the Wind Up Battery steps in; re-charge these cells via the conventional battery charger OR use the hand-crank to wind up and source-up some juice. Kinda like your hand-crank radios. A simply superb concept!
