It is a new idea for a cell phone that converts the users voice tinto the energy it needs to communicate.
Creating this device would revoulutionize the cell phone industry, however you would have to talk in order to send a text message, which would be godd for for teachers, and eavesdroppers, but more entirely more energy efficient.
This would definitely revolutionize the world of cellular phones. If one is stranded with low battery, they may just talk on the phone and regain energy. Some of us get nervous when they battery level decreases halfway, but now you can just call your grandma or uncle or aunt and recharge!
However this could cause a problem for some cell-phone users that only text. These days it is rare to call someone for information. And what about people with hearing disabilities who only text as a form of communication? This would be an advance it technology, but also a setback for many.
In some ways this can be very beneficial to people. I think it can save time and money, because many people spend money on a day to day basis buying either a new cell phone charger or even a new battery for their phone. This is very safe also, because in case of an emergency your cell phone will not die because all you will need to power it will be the sound of your voice. I think it will also cut down on kids using their phones during school, which will better enhance their intelligence!
