Preamble to Solar Wind
Understanding solar wind is foundational for grasping the potential of solar wind electricity generation. Solar wind is a continuous stream of charged particles released from the upper atmosphere of the Sun, predominantly composed of electrons and protons. Its significance lies not only in its role in space weather phenomena but also in its capacity to generate electricity through interaction with planetary magnetic fields.
