(DOHA, Qatar) -- With temperatures in the summer sometimes reaching 122 degrees Fahrenheit, government scientists in Qatar are working on ways to keep fans cool ahead of the 2022 World Cup, to be hosted in the country.
Some parts of the open-air stadiums will be cooled with solar-powered air-conditioning units, but the bottom line is that it’s still going to get very hot in the arenas as spectators sweat out the tournament, in more ways than one. So Qatari scientists have come up with an idea for artificial clouds that will shield the fans from direct sunlight.
The plan is to develop zeppelin-like inflated platforms that move easily and are wind-resistant. Since they’ll be filled with helium and made from ultra-light fabrics, these "clouds" -- at an estimated cost of $500,000 apiece -- will be about as light as the real ones, and can be moved as necessary to block the sun, providing shade to cover the whole stadium if necessary.
