Solar Updraft Tower MIT Architecture

Solar Updraft Towers can be built in desert countries either to cover regional demand resp. to save oil reserves, or to contribute to the energy supply of e.g. Europe, since the electricity produced by Solar Updraft Towers in the sunny countries can be transported and sold to any place either by transmission lines or as liquid hydrogen by ships without substantial losses. Solar Updraft

Solar power tower Wikipedia

As solar power towers commonly use steam to drive the turbines, and water tends to be scarce in regions with high solar energy, another advantage of open pits is that they tend to collect water, having been dug below the water table. The Pit Power Tower uses low heat steam to drive the pneumatic tubes in a co-generation system. A third benefit of re-purposing a pit mine for this kind of
