Multifunctional Solar Updraft Tower
, 2019 Abstract:The Multifunctional Solar Updraft Tower is a prototypical tower that incorporates optimal environment for energy generation. The tower incorporates the solar updraft concept, which uses air movements to rotate turbines and generate energy. The tower utilizes a series of solar collectors, wind, oil pipes, and molten salt to produce energy.
