It seems there is plenty of wind to fuel this fire. Just some information for everyone. I'm going to study up on this one before I jump in. We covered this in high school and college physics, but never at a practical level. "The second law of thermodynamics deals with entropy (S) which is a measure of disorder. The second law says that the entropy of the universe increases. An increase in an overall disorder is a spontaneous change. If the volume and energy of a system are both the same , then every change in that system increases the entropy. If either the volume or energy changes, then the entropy of the system can actually decrease. But, the entropy of the universe doesn't decrease. The molecules in one's body exist in great order; this only happens because the entropy of the rest of the universe is increasing to a greater amount than the entropy of the body, which is decreasing." Definitions------ "Entropy: The thermodynamic quantity that describes the degree of randomness of a system. The greater the disorder or randomness, the higher is the statistical probablility of the state snad the higher is the entropy" " Spontaneous Change: A change that occurs by itself without outside assistance." Interesting link. H
