You're going to get about 30% kinetic energy at best from either.
The first term is the kinetic energy of the field.
The kinetic energy of the ground state cannot be removed.
For a set of objects to have kinetic energy, they must be moving.
Kinetic energy can be passed from one object to another.
Or one could simply have viewed it as a study in kinetic energy.
The faster a car is going, the more kinetic energy it has.
Further, the kinetic energy functional of such a system is known exactly.
They all lose their internal kinetic energy to the outside world at some rate.
The total kinetic energy is the sum of the two.
