Zero point energy
From SGCommand
In physics, zero-point energy is the lowest possible energy that a quantum mechanical physical system may possess and is the energy of the ground state of the system.
Zero Point Modules are incredibly long-lived power sources of great magnitude, which draw zero point energy from a layer of subspace. Another way to draw zero point energy is by using a matter bridge. (SG1: "Lost City, Part 1") (ATL: "Rising")
