This study presents a review and comparison on the power generation by artificial vortex approach. The basic principles of the artificial vortex theory are presented to comprehend the topic. The main characteristics of the components, working principles and features of the existing Vortex Generator Systems for the production of electricity have been discussed and compared. The literature demonstrates that there are two ways to establish the vortex updraft flow: (i) by constructing a special design of the updraft tower to yield a vertical pressure gradient along the axis of a vortex. These types of system have a high investment cost due to the tall tower, or (ii) by using an external heat source to create large temperature rise in ambient air and enhance the buoyancy forces. This integration between the vortex generation system and the wasted heat source is restricted operation in the industrial areas. Therefore, enhancement and development of the way to use a simple construction design based on the solar energy as a heat source support the technology of electricity production by artificial vortex generation. A solar based vortex power generator could be a potential technology for electric power generation, especially in the desert and rural areas. © The Institution of Engineering and Technology 2017.
