...tters (to appear) The sun generates energy through nuclear fusion but there is more than one way for this to occur. The standard solar model says that 98.5% of the energy comes from p-p chains (reactions of very light elements) and 1.5% comes from the CNO cycle (carbon atoms causing nitrogen and oxygen atoms...Natural Science and Public Health: Prescription for a Better Environment
