Harnessing Artificial Tornadoes as an Energy Source
An atmospheric vortex engine (AVE) uses a controlled vortex to capture mechanical energy produced when heat is carried upward by convection in the atmosphere. A tornado-like vortex is produced by admitting warm or humid air tangentially into a circular arena. Tangential entries cause the warm moist air to spin as it rises forming an anchored convective vortex. The work of convection is captured with turbines located at ground level around the periphery of the arena. The heat source can be solar energy, warm water or waste heat.
The vortex engine has the same thermodynamic basis as the proven solar chimney except the physical tube of the solar chimney is replaced with centrifugal force. There is no need for a solar collector - The solar collector is the earth’s surface in its unaltered state.
An AVE power station could have a diameter of 200 m and generate 200 MW of electrical power at a cost as low as $0.03/kWh.
The vortex engine alleviates global warming by reducing fuel required to meet energy needs.
