An elevated or ground level vertical cylinder contains a cone structure that may have an exterior lower static screw auger blade that adds cyclonic turbulence to the rising heated air within the cylinder. The additional turbulence increases the speed of a top propeller which increases the amount of electricity generated. The lower screw auger blade may also be connected to an upper screw auger blade and rotate freely around the cone in response to the rising air in the cylinder to add further torque to a vertical drive shaft. Voids in the cylinder may be used to secure mirrors or lenses to increase the temperature of the cylinder. Mirrors may be attached to the cone to further reflect solar energy to increase the air temperature within the cylinder. The outside perimeter of the cylinder receives solar energy by use of mirrors and lenses directed toward the cylinder.
