    ABSTRACT

Many models of baryogenesis, such as the Affleck-Dine model, utilize the coherent time-evolution of a baryon-number bearing scalar field to generate baryon-number. This this talk. I point out the resemblance of the problem to the theory of biological motors in which biassed motion is driven by ATP hydrolysis. I argue that a similar mechanism may be implementable in the particle theory context, and lead to interesting model building possibilities.
