"Now this isn't just some theoretical math proof. This is a functioning piece of technology – one that literally moves heat from our space/time and vents it out into another space/time."
― Malcom Tunney (Stargate: Atlantis)
""If you let the energy in your own body flow, the lightning will follow it. You must create a pathway from your fingertips up your arm to the shoulder, then down into the stomach. The stomach is the source of energy in your body; it is called the sea of chi. From your stomach you direct it up again and out the other arm. The stomach detour is critical; you must not let the lightning pass through your heart, or the damage could be deadly."
