Abstract: Embodiments of the present invention can harvest wind energy based on the transport of air ions using Solid-State Wind-Energy Transformers (SWETs). These devices comprise coronal emitters that create charged air molecules. The charged air molecules are transported by wind to create useable electric power. SWETs can be deployed on existing structures, such as power-line poles or buildings, potentially eliminating much of the costs associated with other renewable energy systems.
