  We propose a new alternative for baryogenesis which resolves a number of the
problems associated with GUT and electroweak scenarios, and which may allow
baryogenesis even in modest extensions of the standard model. If the universe
never reheats above the electroweak scale following inflation, GUT baryon
production does not occur and at the same time thermal sphalerons, gravitinos
and monopoles are not produced in abundance. Nevertheless, non-thermal
production of sphaleron configurations via preheating could generate the
observed baryon asymmetry of the universe.
