I have been thinking about this for a long time now and in therory it works. What im wordering is if you could make it work in place of the traditional power outlet. Here it is, basicly there are just coils of wire inside of a transformer, on coil has say 240 turns of coil. Inside of this coil is another coil with 240 turns also. So the voltige inside the first coil will be the same as the second coil. And to half the voltige in the first coil. If you had a plug that was just a cilender with a coil of wire inside and an outlet that was a hole in the wall with a coil inside. I know a hole in the wall with 120 volts running through it sounds scary , but put a plastic cylinder inside the hole and vurtaly no shock hazerd.
sorry for the spelling errors spell check was not working.
