The vortex I am referring to would be a tornado. The formation of this vortex is fascinating. Within the cone of the vortex a condition exists for formation of lightning. Many actual movies taken of moving tornados show what first appears to be the vortex cone destroying power lines which short and spark. A closer look at the films show a "glow" within the cone and no power lines close. ----- Original Message ----- From: "Grimer" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, August 02, 2004 12:07 PM Subject: Re: ...upon the clouds of heaven...
