Switch and wire are both inseparable bond. These are both necessary to turn on the lite and the fan.
However, efforts are on for several days to generate electricity without electricity.
Some of the latest Disney researchers have studied this way. Electricity is used in a room without wires.
The walls of the room were built with aluminum foil rather than cement and brick. The copper rods were placed in the middle of the room and it had 15 capacitors.
Electricity has been provided from the outside. Once this setup was turned on, the magnetic field was created and the flow of electricity was in the room.
The experiment was a good result and found some barriers. Overcoming them will soon be taken out of the full-fledged power drain project.
