In these uncertain, changing times, when extreme temperatures are adversely affecting humanity, Dubai Holding plans to show to the world how enclosed temperature-controlled cities could be a solution to these increasing problems.
Using 4.5 miles of enclosed "network of temperature-controlled openable promenades", visitors will be able to stay in this for weeks together without the need for cars or exposure to Dubai's scorching heat with temperature around 104°F outside during summer. In the winters when Dubai's temperature is pleasant @ around 73°F the city's enclosed promenades will be opened to allow in the breathable fresh air.
Touted to be the largest theme park in the world, The Mall of the World will also include a "wellness district" to attract medical tourists and West End / Broadway-inspired theatres. The plan is to promote Dubai as an all-year-round tourist destination by providing an enjoyable temperature-controlled environment in the summers.
There is no announcement as to how and when the project will be completed, but it is a novel idea.
