Default Where Does the Power Go?

Jim, when I get back from my trip, I'll tell you about temporary
benign interference Vs permanent active interference.



A standing
wave in a constant Z0 environment is temporary interference.
Wave cancellation is permanent active interference. When wave
cancellation occurs, the energy and momentum are redirected. In
a transmission line, there are only two directions. In the direction
of the wave cancellation and in the opposite direction. The energy
doesn't go in the direction of wave cancellation so which direction
does it go. Boy, that's a tough question, isn't it?


As far as I know, there has never been any dispute over which
direction the energy goes. The problem has always been with your
overly imaginative explanation for how it gets there.

Have fun on the hog. Last weekend I was fortunate enough to drive 20
laps on a 1/2 mile banked track in a Busch class stock car. Holy cow.



Back when I lived in CA, in between motorcycle races, they opened
Laguna Seca to anyone with a motorcycle license, street legal bike,
$20, and willing to sign a waiver. Everyone was a certain number
of minutes apart. I got my Kawi Z1-B up to about 135 mph on the
straightaway. And that still wasn't top speed. That machine red-
lined at 60 mph in *first gear* with four more gears to go. :-0


Getting speed on the straights is the easy part. Finding out that
you've got too much when you arrive at the turn is the primary concern.
