Abstract
We discuss a new mechanism for generating currents in superconducting cosmic strings. If energy is deposited inside a string in the form of the current-carrying fermions then a combination of the inherent directionality of the string (and its zero modes) and CP violation will produce a net nonzero current. Various sources of energy are discussed including the interaction of strings with ambient particles. Another source could be phase transitions which take place inside strings. We discuss such phase transitions at length and briefly discuss other possible consequences of them.
