TED Talk: How to Air Condition Outdoor Spaces - By Wolfgang Kessling
Rating: ****
In this TED talk, Wolfgang Kessling talks about how he plans to put to use an innovative way to cool outdoor spaces so that the 2022 Football World Cup may be held in the hot arabian country of Qatar.
Kessling explains that the past world cup stadiums, as well as many other football stadiums around the world have not taken into account the comfortability of the air. It seems to be overlooked, as most stadiums simply use the heat to advantage and make spectators pay more for shaded seats. Why do this when there is easy and effective ways to cool these open-air stadiums so that spectators, as well as players can enjoy the game to it’s full potential. He explains what causes the uncomfortability for most outdoor events held in places of hot climates and explains how this may be counteracted using tubes of cold water and strategic shading to reflect cool, dry air towards the stands and field. This system is proven to be effective and efficient.
I thought this concept was really cool and has amazing potential. I know how uncomfortable outdoor events like concerts can be in the summer heat. I think I would pay more for a concert knowing that I can be comfortable throughout and not in need of water bottles the whole time.

Saunders attempted to break the speed record for a solo walk to the North Pole in 2008,when his journey stopped suddenly in that same year and again in 2010 because of equipment failure. This expedition is planned to start again in the spring of 2011. Saunders id to hike 478-miles from Ward Hunt Island, Canada to the North Pole. 1,800 miles into the hike, it will known as the “longest unsupported polar journey of all time”.
"Humbly framed as the ambitious undertakings of an ardent athlete, visceral first-hand accounts of just how much things are changing in the Arctic -- the 'barometer of global climate change.'" - Saunders treks officer.
