ResumoIt is shown that one of the family of "generalized energy density" definitions being investigated by Komar, one for which the generalized energy density is made positive definite by use of minimal surfaces, leads to a total "generalized energy" which (a) is undefinable for closed universes, (b) is not conserved for some asymptotically flat spaces, and (c) is not the correct total energy for the Oppenheimer-Snyder collapsing star metric where the metric in a neighborhood of infinity is identically the Schwarzschild metric.
