I have invented an efficient way to capture energy from the sun using a hyperbolic chamber that draws air through its center by way of convection and differential pressure created by the sun and wind flow. The second part of my invention is a unique DC generator that has very low AC losses.

The sun heats the top inner surface of the hyperbolic tower causing the air to rise, drawing air from the bottom through the center of the tower. Air flowing through the center of the tower speeds up according Bernoulli's Theorem, which states that an increase in the speed of moving air or a flowing fluid is accompanied by a decrease in the air or fluid's pressure. A propeller situated at the center of the tower is attached a generator producing electricity in very hot, arid locations.
