Mainstream physics believes our Sun is powered by nuclear fusion providing an outward pressure that has to be balanced by the inward force of gravity. But would nature use such a complicated process as nuclear fusion when there is a much simpler alternative in the form of an ionized plasma dynamo. A spherical plasma dynamo would take energy in the form of plasma flow from the local interstellar medium converting it into electromagnetic energy forming heat and light. Neutral particles from the local interstellar medium would become ionized spiralling down forming an electrical current in the plasma flow. This would power the plasma dynamo that would act like a superconducting coil producing the Sun’s magnetic fields.
