What is the minimum size of a vortex engine?
Physical models show that it is possible to produce very small vortices. There is a minimum economical size for vortex power producers and vortex cooling tower because small vortices are more likely to be disturbed by the wind and because there must be an attended control system. The minimum practical size could be 50 MW(t) for vortex cooling towers and 50 MW(e) for vortex engines.
