Qatar 2022BBC 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.

Solar Death RayWhat a great hobby for the budding comic book super-villain. Could Lex Luthor do this in his youth? Nice work. Via Eric Jacqmain’s YouTube:

The R5800 is my latest and greatest solar creation. Made from an ordinary fiberglass satellite dish, it is covered in about 5800 3/8″ (~1 cm) mirror tiles. When properly aligned, it can generate a spot the size of a dime with an intensity of 5000 times normal daylight. This intensity of light is more than enough to melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant. It stands at 5’9″ and is 42″ across.
