Wind towers
Aren't solar updraft towers an idea that have been employed in Dubai and elsewhere for many years?
These new ones would be nearly as tall the Burj Khalifa.

As best I remember, the towers in Dubai were downdraft towers, designed to channel breeze into buildings. They also did not drive anything. They were purely a low tech form of air conditioning.
A number of people, including architects, have remarked on how sensible the traditional Gulf architecture was, especially relative to free-standing, glass-walled, air conditioned modern buildings.

^ is right. These updraft towers are a succession to the 'heat stack' concept, not wind towers. The concept is not new either but I guess the element of purposefully increasing hot air updraft and powering a turbine with it is new and fairly ingenious. This could work well in other hot countries.
