We propose two mechanisms whereby compact coalescing binaries can produce relatively ‘clean’ fireballs via neutrino–antineutrino annihilation. Pre-ejected mass due to tidal heating will collimate the fireball into jets. The resulting anisotropic gamma-ray emission can be efficient and intense enough to provide an acceptable model for gamma-ray bursts, if these originate at cosmological distances.
