There is considerable interest in the propagation dynamics of intense neutrino beams in a background dispersive medium such as dense plasmas, particularly in the search for a mechanism to explain the dynamics of type II supernovae and gamma ray bursters. Employing the relativistic kinetic equations for neutrinos interacting with dense plasmas via the weak force we explore collective plasma streaming instabilities driven by neutrino beams. In particular we examine the anomalous transfer between neutrinos and the dense supernovae plasma via excitation of electron plasma waves and transverse waves. It is demonstrated that approximately 1% of the neutrino energy is deposited close to the core raising the electron temperature from 100keV to 500keV sufficient to explode the outer mantle of the collapsed star. Another interesting result is an asymmetry in the momentum balance imparted by the neutrinos to the core of the exploding star due to symmetry breaking by the collapsed stars magnetic field. This results in a directed velocity of the resulting neutron star or pulsar explaining the so called birth velocity.
