We discuss a new class of trajectories of loops of cosmic string which are more generic than the ones considered thus far. The gravitational and Goldstone-boson radiation from such loops is calculated and is found to be of the same order of magnitude as radiation due to other loops. If the string is superconducting, the loop emits ‘‘fanlike’’ beams of electromagnetic radiation and the energy emission is strongly anisotropic.
