Can electrons flow in opposite directions on the same wire, see schematic!

I made a new video,concerning electron flow,this time I think I got it right.http://www.youtube.com/watch?v=b8eUbyWa-cY

Please, could you add diode to this short wire where electrons are flowing both directions in such direction to allow only one of this flow. I'm very curious about this but can't check it.Thank you.

I'm not sure this is real relevant but I had a handheld   radio transceiver that had a coax cable coming out of it to go to the antenna.  It transmits RF (high frequency AC) out the antenna.  That SAME coax (two wires as in a center wire and a shield as the second wire) was used to feed DC power in to the transceiver.  This was a mod with a diode to save having two separate cables (or 4 wires) going to the radio.  So you had DC going in on the same wire that AC was going out when it transmitted.  In that configuration it did not use any internal batteries.  It worked fine.

Reminds me of some solar panel experiments I have did in the past, and found out rf can power a solar cell, believe it or not its true. Also many solar cells use the non visible spectrum of light for energy conversion, all tho most would assume its the visible spectrum they use. For example I took my roomba ir virtual wall. It simply shines a light not in the visible spectrum,,that the roomba can see and so it avoids that area. Anyway the virtual wall ir light can actually be seen as visible light when viewed in a digital camera. So I took the virtual wall and in a dark room turned it on with its Ir led facing the solar panel,,the panel was connected to a meter,,and you can see how each time the virtual wall is turned on the meter shows voltage from the solar cell and that reading goes off soon as you turn the virtual wall off or face it another way..Very interesting I thought..

Worst case Im wrong, its still a very handy concept to ponder I think. Best wishes steve....

If you think you may be right you need to keep pondering it. I still think there is more going on than meets the eye. I will say this. Ive taken two aaa batterys and put the same polarity's together and measured the voltage. With the positve the voltage reads over 100 millivolts with the pos sign. The neg polarity's read exactly the same but with the neg sign. The amps were .2 microamps. Not even close to being one microamp.
This is still very interesting.

Electron's have, and always will travel in opposing directions on the same conductor, period.

That said, put two diodes in parallel ,
on facing one way,
the second the opposite.

Place this bi-directional gate into the center (green) wire
then measure the voltage drop across both diodes and see.

better yet, use an oscilloscope,
and watch current flow in BOTH directions simultatiously...

Please note, in a perfect world, and a perfect resistive network,
as in poynt99's textbook example above, no currunt will flow.

All respect meant there .99, but this example isn't
a "Static" purely resisitive experiment however.

Nice nick BTW, good word-play:
http://en.wikipedia.org/wiki/Poynting's_theorem

But in the real world these motors will draw and release (BEMF) current
in both directions in that center-tap green wire that can be observed.

This is most notibly used in the RF field with many items
that need to be remotely powered from a distance,
but use the same conductor as the RF return path as well,
like mast-mount antenna preamps, many marine products too,
such as the very common mod e2matrix observed.

The DC rides the core to to the preamp,
the RF rides the skin-effect back to the decoupler.
