Electric

Movement causes electrons to become displaced.
(Heat is movement.)
Displaced electrons = negative ions.
The electrons will be drawn to positively charged protons.

Their quest for unification is electricity.
The important aspect of their dance is the movement, the questing...
that is electricity.

Once they obtain their blessed reunion with protons, the movement has ceased.
The flow has stopped and will lie in wait for a new burst of movement.

Energy is in the movement and not in the arrival.
