  In order to get geodesically complete Reissner - Nordstroem space - times, it
is necessary to identify pairs of singular points. This can be done in such a
way that "wormholes" are created which generate electric field lines without
any charge. Finally, it is shown that it is possible to glue these space -
times not in the singularities r=0, but at some r>0. The surface energy
generated by this gluing is exotic, but tends to zero in the limit r -> 0.
