Charger is connected to the air

The American company RCA had demonstrated a prototype of a fundamentally new charger designed for portable gadgets. It does not need to connect to the network and converts it into electricity the energy of electromagnetic waves Wi-Fi range.

A small device called Airnergy, was demonstrated at the recent exhibition CES-2010. Its dimensions are only two to three inches, and the approximate cost is at the level of 40-50 dollars. Despite these inconspicuous indicators tested instance Airnergy just half an hour to charge the battery BlackBerry for 30%.

Inside the Airnergy is a complex series of schemes that will transform Wi-Fi signal in electricity, charging with built-in battery. After charging the device can be connected to any other through-pin mini-USB, to serve as an additional source of energy.As the developers, the effectiveness of their "charge" depends on the distance to the nearest Wi-Fi access point. According to Computerworld, the current RCA works to reduce the size of your device, and hopes to release the 2011 serial "exercises" are placed in the battery compartment regular mobile phone.

Experts newspaper Guardian confident that chargers like Airnergy, can never be powerful and fast. However, along with wireless internet access in the modern world, many more sources of electromagnetic radiation - from cell phones themselves to microwave ovens. The idea to use "free" electricity is promising, it is necessary only to establish a mechanism of absorption.
