The Wingless Electromagnetic Air Vehicle (WEAV) is a heavier than air flight system in development for NASA at the University of Florida. The WEAV was invented by Dr. Subrata Roy and has been a subject of several patents. The aircraft uses electrodes on its undercarriage in order to ionize air, and it then propels the resultant plasma using electromagnets. The high pressure zone created underneath the aircraft is consequently used to create thrust for propulsion and stability.
