Artificial cloud to cool open playgrounds

Dubai: A Qatar-based engineering teacher has unveiled a design of an
artificial cloud to shade and cool the open playgrounds to be used
during the 2022 World Cup in Doha.

Saud Abdul Ghani, head of the Mechanical and Industrial Engineering at
Qatar University, said that the project will be executed in
collaboration with Qatar Science and Technology Park.

"Artificial cloud will move by remote control, made of 100 per cent
light carbonic materials, fuelled by four solar-powered engines and it
will fly high to protect direct and indirect sun rays to control
temperatures at the open playgrounds," he told the local Arabic media.

Abdul Ghani said the initial model of the cloud cost USD 500,000 but
the cost will decrease upon launching commercial models which could
also be used at beaches, car parking by using the mobile phone.
