how does vaccum energy work?

Answer 1

via the pressure of air that tries to fill that vacuum

Answer 2

A Distillation: THE SECRET TO ANTIGRAVITY: Provide a periodic opening to gate a rotating magnetic field. This utilizes the inertia of the rotating field to tear part of it away from the main aetheric field. The loss of this field will create anti-gravity and at the same time induce 'dark energy' into the gate, causing the net system energy to move to the negative polarity. This is generally related to the proton magnetic field energy and is most easily achieved using ferromagnetic materials wherein some electrons in the outer orbitals do not cancel the net nuclear proton spin field. (Thus it is not the outer orbital electron spin that creates the ferromagnetic field, but rather the lack of cancellation of the proton spin field.)

Answer 3

Are you talking about a vacuum cleaner, or about the "work" that keeps a suction cup stuck?

What really keeps a suction cup stuck is the air pressure on the outside, about 14 lbs per square inch. If there is no air underneath it, the air ion the outside is pressing against the cup and makes it stick to the glass.
