An Atmospheric Vortex Engine (AVE) uses an artificial vortex to capture mechanical energy produced when heat is carried upward by convection in the atmosphere. (vortexengine.ca)
The atmospheric vortex engine exploits the natural energy content of the vortex produced during upward heat convection in the atmosphere. (powermag.com)
«This has to do with water vapor, which is the fuel for explosive deep convection in the atmosphere. (sciencedaily.com)
