BBC Sport reports:
Scientists at Qatar University claim to have developed artificial clouds to provide shade for stadia and training grounds at the 2022 World Cup.
The fierce summer heat in the Gulf has led to concerns about conditions for players and fans at the tournament. Temperatures in June and July can reach up to 50 C.
Qatar were announced as hosts in December, and Fifa president Sepp Blatter initially said he expected the 2022 competition to be moved to winter.
But Blatter has since stated that he feels the tournament will go ahead as planned in the summer months. Qatar plan to air condition their World Cup stadia via solar power, and now scientists have designed the ‘clouds’, which can be produced at a cost of $500,000 (about £310,000) each.
