Abstract
Solar updraft towers offers a simple and alternative method of generating electricity. However, it is unclear on how to build a tall, free standing structure that can withstand the unpredictable and destructive force of the wind. A tower consisting of stacked inflatable toroidal elements have been suggested and the dynamics of the tower will be analyzed. Using Lagrangian reduction by symmetry, the theory for the 3D motion for the tower is developed. By confining the motion to two-dimensions, numerical simulations are performed to study the tower's stability and is compared with the data collected from a experimental prototype showing good agreement with theoretical results.
