Abstract
In this paper we discuss a simple Casimir-type device for which the rotational energy reaches its global minimum when the device rotates about a certain axis rather than remaining static. This unusual property is a direct consequence of the fact that the moment of inertia of zero-point vacuum fluctuations is a negative quantity (the rotational vacuum effect). Moreover, the device does not produce any work despite the fact that its equilibrium ground state corresponds to a permanent rotation. Counterintuitively, the device has no internally moving mechanical parts while its very existence is consistent with the laws of thermodynamics. We point out that such devices may possibly be constructed using carbon nanotubes subjected to the strong—but experimentally feasible—magnetic field. The effect in the carbon nanotubes is enhanced due to the presence of massless charged excitations. We call this “zero-point–driven” device as the perpetuum mobile of the fourth kind.
