Gravitational Generator

  1. Ok this one is purely theoretical and I'm going to just make some assumptions.
    1. No Debris will block the way.
    2. Its A vacuum
    3.The structure won't collapse.

    Ok, first we drill a hole through one side the earth and out the other. We then wrap the new whole in a superconducting coil of wire. At both ends of the wire attach a battery to collect the energy. Then drop the magnet.

    Would the magnet be slowed?
    I came up with this today and only researched a little on how magnetic generators generally work.
    Squares are magnets. The brown lines are the wires previously mentioned.

    Yes, the magnet will be slowed. There are videos of people dropping magnets down copper tubes on youtube that should show this.
     
  4. Thanks for the reply I had this idea milling around in my mind all day. :D

    This is only a one shot device, remember. The magnet will oscillate along the polar axis but the displacement will gradually die down as energy is used up. It is a very expensive way to harvest the PE of a falling object. Remember, you had to dig out all that material to make the hole in the first place. That would involve much more energy than you will get out.
