"A recently issued patent describes a method by which vacuum energy is extracted from gas
flowing through a Casimir cavity. According to stochastic electrodynamics, the electronic
orbitals in atoms are supported by ambient ZPF. When the gas atoms are pumped into a
Casimir cavity, where long-wavelength ZPF modes are excluded, the electrons spin down
into lower orbitals, releasing energy. This energy is harvested in a local absorber. When the
electrons exit the Casimir cavity, they are re-energized to their original orbitals by the
ambient ZPF. The process is repeated to produce continuous power. This method does not
suffer from the fundamental flaws of the other approaches, and might work."
