  We show that generic anisotropic universes arbitrarily close to the open
Friedmann universe allow information processing to continue into the infinite
future if there is no cosmological constant or stable gravitationally repulsive
stress, and the spatial topology is non-compact. An infinite amount of
information can be processed by ``civilisations'' who harness the temperature
gradients created by gravitational tidal energy. These gradients are driven by
the gravitational waves that sustain the expansion shear and three-curvature
anisotropy.
