	abstract = {Using ideal magnetohydrodynamics we examine an outflow from a disk surrounding a stellar-mass compact object. We demonstrate that the magnetic acceleration is efficient (>~ 50\% of the magnetic energy can be transformed into kinetic energy of γ > 10<SUP>2</SUP> baryons) and also that the jet becomes collimated to very small opening angles. Observational implications, focusing on the case of an initially neutron-rich outflow, are discussed in K{\"o}nigl{\textquoteright}s contribution.},
