Abstract
We point out that the recently proposed model of a flat 4-dimensional universe with accelerated expansion is a special case of time-dependent solutions that the author found under the name of ``S-branes.'' We also show that similar accelerating models can be obtained from S-branes if the internal space is chosen to be hyperbolic or flat spaces.
