Engineers Develop Solid-state Fan
The device operates thanks to a phenomenon called corona wind. This corona wind is created by placing a series of live wires within uncharged conducting plates contoured into half cylinders, partially enveloping the wires. The live wires generate micro-scale plasma that conducts electricity.
The corona wind is created within the intense electrical field that results from the configuration of the wires and the conducting plates. The researchers say they were able to control the micro-scale discharge to produce maximum airflow without risk of arcing or sparks which could prove catastrophic to electronic devices
