  We discuss a pulsar acceleration mechanism based on asymmetric neutrino
emission from the direct quark Urca process in the interior of proto neutron
stars. The anisotropy is caused by a strong magnetic field which polarises the
spin of the electrons opposite to the field direction. Due to parity violation
the neutrinos and anti-neutrinos leave the star in one direction accelerating
the pulsar. We calculate for varying quark chemical potentials the kick
velocity in dependence of the quark phase temperature and its radius. Ignoring
neutrino quark scattering we find that within a quark phase radius of 10 km and
temperatures larger than 5 MeV kick velocities of 1000km s$^{-1}$ can be
reached very easily. On the other hand taking into account the small neutrino
mean free paths it seems impossible to reach velocities higher than 100km
s$^{-1}$ even when including effects from colour superconductivity where the
neutrino quark interactions are suppressed.
