Thus far the origin, evolution, and large scale characteristics of the solar wind have been addressed using MHD theory and observations. In this lecture we consider aspects of the solar wind that either involve phenomena on small scales or that require the use of kinetic rather than fluid physics. Topics discussed include magnetic turbulence, acceleration at CIRs and transient interplanetary shocks, type III solar radio bursts, radial variations in the quantities predicted by the MHD theory of the solar wind, and pickup ions with origins in the interstellar medium and comets.
