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.
