Аннотация: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.
