Qatar Hopes to Cool Stadiums with Artificial Cloud

A Qatar University group of scientists has designed a remote control artificial cloud that would hover like a helicopter in the air during the 2022 World Cup to cool off stadiums and shield them from the desert country’s blistering summer sun.

Saud Abdul Ghani, head of the university’s Mechanical and Industrial Engineering department, said his group would collaborate with the Qatar Science and Technology Park to build a prototype of the cloud at a cost of about $500,000.

The cloud, filled with helium and built of light carbon material, would use four solar-powered engines provide shade by manoeuvring between the stadium and the sun.

Ghani said commercial models could be used at beaches and car parks and could possibly be fetched by mobile phones.

Qatar was awarded the hosting of the 2022 World despite a warning by FIFA investigators that s that the summer heat – which can rise to 50° Celsius or 122° Fahrenheit – could pose a potential health risk to players, officials and spectators.
