Thermodynamics of Margulis Space Time:  In this talk I will describe the stable and unstable leaves for the geodesic flow on the space of non-wandering space like geodesics of a Margulis Space Time. I will also show that monodromy of Margulis Space Times are ``Anosov representations in non semi-simple Lie groups''. Finally using the Anosov property I will define the Pressure metric on the Moduli Space of Margulis Space Times without ``cusps'' and show that it is positive definite on the constant entropy sections.
