We report quantum Monte Carlo calculations of superfluid Fermi gases with short-range two-body attractive interactions with infinite scattering length. The energy of such gases is estimated to be (0.44+/-0.01) times that of the noninteracting gas, and their pairing gap is approximately twice the energy per particle.
