  In the present paper, it is shown that the existence of the Casimir
electromotive force (EMF) is possible in nanosized configurations with
nonclosed nonparallel metal plates. The nature of such EMF is associated with
the drag current generation at the noncompensated Casimir action of virtual
photons on the electrons in the nano-configurations. In the case of a classical
configuration withstrictly parallel plates, EMF is not generated. However, EMF
can be generated when even an insignificant angle between the plates appears.
Angles between the plates and their effective lengths have been found, at which
maximally possible EMF is generated in a configuration.
