Hello, I am sure you have all already heard about the efforts in making wireless power happen. One way I am looking at this is I think electro magnetic power. You know you get those toothbrushes that you put on the stand and they charge without any cables. Well I am wondering how they do this! Also I would like to know if you could do it on a larger scale with a larger voltage and current!? Any help would be appreciated greatly! Thanks a lot
