An artificial cloud design has been unveiled by a Qatar-based engineering teacher to shade and cool the open playgrounds during the 2022 Football World Cup in Doha. Made completely of light carbonic materials and fuelled by four solar-powered engines, the artificial cloud will move by remote control, said Saud Abdul Ghani, head of the mechanical and industrial engineering department at Qatar University adding the project will be executed in collaboration with the Qatar Science and Technology Park. “It will fly high to block direct and indirect sun rays and control temperatures at the open playgrounds,” he added. Abdul Ghani said the initial model of the cloud will cost $500,000 but the cost will decrease upon launching commercial models. These could also be used at beaches and car parks and could be controlled using mobile phones.
