Default Travelling through a tunnel of electricity/plasma...



Hello,

Idea is to:

1. Make tunnel of electricity like lightning.

2. Then maybe travel through tunnel of electricity.

What your thoughts on that ?

Alternatively:

What happens during static discharge... ?

Electrons jumping from atom to atom... but even through the air ?!

It seems air molecules pushed aside...

What's there instead ? Just pure energy ?

Maybe gravity is bend ?

Maybe just plasma like a tunnel of plasma.

Bye,
Skybuck.

No big deal. When electrons travel "down", ions travel "up".


Stripped from atoms / molecules, and then through the air, yes.


Heated, then become very sparse.


Light, very fast moving hot gas, which cools very quickly.


No.


Probably not.

Current itself does not create conductivity or enhance the
conductivity of a conductive path. Current through a resistor does
not necessarily change resistance. Heat from the current can alter
conductivity. Volts can ionize molecules to enhance conductivity.
Humans cannot travel through a conductive path.

Ok, volts can drive electrons in one direction and drive ions in the
opposite direction. Perhaps electrical circuits are more complex.

Consider an LC oscillator.
During the half cycle before voltage reaches a maximum level, current
is charging a capacitor. Current is flowing (delivering electrons) by
removing electrons from the relatively positive end of a capacitor and
delivering them to the negative end of a capacitor. In this respect,
current is flowing from positive to negative.

Note: When either magnetism or voltage reaches maximum level, current
reverses. The reverse in current indicates an instant reversal of
voltage or magnetism polarity. I doubt that point charge displacement
(voltage) can instantly convert to reverse charge positions. I wonder
how and why near zero voltage applied to the oscillator's coil can
cause instant reversal of point charge velocity (magnetic polarity
reversal).


An arc can be low temperature, thus thermionic emission is not
necessarily responsible for spark current. Even if a molecule in an
electrode ionizes, that ion does not necessarily change condutivity of
air (electrons repel each other).

I suspect that volts can cause polarization of molecules already in
the air. Polarized molecules can have much greater conductivity that
neutral molecules. For example, oxidation state (related to polarity)
influences conductivity.

Before arcing, air is an insulator. An arc has relatively high
conductivity. As mentioned previously, creation of point charges in
air does not necessarily create a conductive path, because point
charges repel each other. Perhaps voltage organizes polarized air
molecules into a conductive path. Perhaps a conductive path of
polarized air molecules is a stable configuration. This stability
aloows an arc to be continuous.

Arcs can be continuous DC. A vacuum between molecules within an arc
is a charged capacitor. Once source volts equal charged vacuum
capacitor volts, current must stop. Since current can continuously
flow through an arc, perhaps the conductive ion path within the arc
does not retain vacuum capacitors.
