Question:
Is it a possibility to send electricity through air over a long distances and be able to use it when it is transferred? If so, what does the machine look like that can do this or what it might look like? Thank You.


Replies:
Sort of. There is a way to induce an alternating current in a conductor far away: by electromagnetic radiation. This, in fact, is how devices such as radio and television operate. The broadcasting antenna sends out radion waves, which are rapidly alternating electromagnetic fields. When these fields contact a conducting material, such as the antenna in your house, it sets up an electrical current which the radio or television then translates into sound or a picture.
