- tedsanders 11y agoActually, solar wind carries about 1,000 times less momentum than sunlight itself: http://en.wikipedia.org/wiki/Solar_sail#Solar_radiation_pressure http://en.wikipedia.org/wiki/Solar_sail#Solar_radiation_pres... Solar sails mostly capture the momentum of sunlight, not the solar wind. (Solar wind is the plasma of electrons, protons (hydrogen nuclei), and alpha particles (helium nuclei) that come off the sun.)
