Scientific paper

Here we present an inhomogeneous cosmological model, in 2+1 gravity, which satisfy all the energy conditions, although it generates non deaccelerated universes. We work in a self-similar 2+1 gravity scenario, in order to simplify the equations system and to allow us to find analytical and simple solutions. Our propose is basically to improve our understanding on the role of inhomogeneities on the acceleration of the Universe.
