I was reading about Marin Soljacic and his research at the MIT Physics department on Wireless Energy. I found it fascinating. The key idea is that energy is transferred through magnetism in the same way electric engines are powered but that this magnetism is created say around a room in a way that only objects designed to “tune in” to this magnetism, say a cell phone, receive it and get charged while everything else in the room is impervious to this energy “floating around”. Or at least this is what I think the idea is…..
