Mystery Source of Solar Wind Heating IdentifiedThe solar wind is hotter than it should be, and for decades researchers have puzzled over the unknown source of energy that heats it. " Consider the coffee. When you stir it with a spoon, the stirring produces swirls and vortices in the liquid. The vortices fragment into smaller and smaller eddies until, at the smallest scales, the motions dissipate and the energy turns into heat. Because energy cascades down from the large swirls to the smaller ones, the process is called a turbulent cascade. Theoretically, the turbulent cascade should heat the coffee. Real coffee cools off, however, because the act of stirring brings warm coffee from the depths of the cup into contact with cooler air above. Cool air absorbs the heat—the heat the coffee had to begin with plus the heat you added by stirring—and you can take a sip without scalding yourself." See the keys works * THE SWIRLS AND VORTICES * EDDIES UNTIL * MOTION DISSIPATES * ENERGY TURNS TO HEAT * called "TURBULENT CASCADE" But there is no cool air in spaceThe magnetosphere protects our planet from solar wind and cosmic rays. It contains the Van Allen radiation belts, auroras, and giant electrical "ring currents" of staggering power. [ link to www.nasa.gov] Do you feel the vibe?
