When FIFA decided to award the 2022 World Cup to the State of Qatar there was a lot of surprise from the other competing countries. Not only was this a big bet from FIFA that a country so small could provide a memorable football tournament, but the temperatures experienced during the summer months when the tournament is played are extreme to say the least.
Come 2022, footballers from around the world will be heading to Doha, in a country where temperatures commonly reach 46 degrees Celsius, and don’t often fall below 29 degrees Celsius.
How do you air condition an open stadium? Qatar University believes it has the answer, and it doesn’t involve lots of air conditioning units pumping out freezing cold air.
Dr. Saud Abdul Ghani, who runs the Mechanical and Industrial Engineering department at the Univeristy, has come up with a very green and nature-inspired way of solving this problem: artificial solar clouds.
If you’ve ever been outside on a very hot day then you know that standing in a shaded area can result in a temperature drop of several degrees. Dr. Ghani’s idea is to create an artificial cloud that would float above the stadiums covering a large area of the playing field in shadow. As the sun in blazing down on the cloud while it is doing this, all power can be generated through solar panels.
The cloud will be constructed of carbonic materials and have four solar engines allowing it to be moved by remote control as well as hover in place.
