  • The ground means ...

    The ground means that you have to connect the ground wire to any grounded metal such as electrical box or the round hole (the third hole) in the outlet, just be careful not to plug it in to the other ones you may get shocked. You can also stick a rod into the ground and connect the ground wire to it.

  • Stealing ...

    Stealing electricity with coils isn't that easy. MythBusters only managed to get eight millivolts from a giant coil set up near high-voltage power lines. (see Tiny URL code 4VWRBS)
