We consider the planar Lorentz gas with finite horizon. The random scenery is give by a sequence of iid square integrable random variables. To each obstacle we associate one of this random variable . We suppose that each time the particle hits an obstacle, it wins the amount given by the random variable associated to the obstacle. We are interesting in the asymptotic behaviour of this amount.
