The phone, which does not require battery for transmission messages and calls, developed by engineers at the University of Washington in Seattle. The developers attempted to create such a device before, but faced with an insufficient amount of energy derived from solar and other sources. Now they were able to solve the problem. Well, almost…
Basis phone — a microwave resonator, which works without batteries and is able to transmit vibrations generated by a human voice, standing next to the receiver.
Some components of the cell, for example, the station responsible for the contact with the network, I had to place near the phone to save power. As the phone receives her signals, and then converts them into electricity, the station is impossible to clean away. In the future the developers plan to build a station in a Wi-Fi router mounted on a cell tower, and increase the distance.
Now the prototype has normal buttons and a tiny screen — for the sake of saving energy is to save all, and the quality of communication is poor. In the nearest plans of developers — to fix the situation, and then provide “up” E-ink display that will allow you to send from your phone full of text messages and track a variety of information. Then, if the power consumption everything will be fine, the phone will provide a no camera.
