  The possibility in principle is shown for the existence of Casimir
electromotive force (EMF) in a configuration with parallel nanosized metal
plates which are shifted relative one another. The effect is theoretically
demonstrated for a configuration with two plates (wings) of finite length, the
particular case of which is classical Casimir configuration with parallel
plates. It is found that when the plates are strictly parallel, EMF does not
appear. However, when the plates are shifted relative one another, in each of
them time-constant EMF is generated. It is also found that maximal EMF values
depending on the plate shifts are larger than those depending on the values of
angles between the wings. All the found effects exist in periodic
configurations with shifted elements. There are optima of the configuration
geometrical parameters at which the EMF generation can be maximal.
