For my blog assignment I chose to discuss a Ted.com video. The video is from Wolfgang Kissling called, “How to air condition outdoor space”. He discusses new ideas on how to cool down stadiums. Today, more and more stadiums are outdoors. For instance, Orlando, Florida has a big outdoor stadium. The humidity and the heat are very high. Also, other stadiums around the world like Greece and Mexico City. Their heat and humidity index above average.  They suggested putting a PVC and solar system around the top of the stadium. They would use renewable energy from the sun. This would cause a shift to reduce the carbon emissions.  I feel this a smart approach for industries and business to move to. It would benefit USA and other countries around he world who can’t afford Air conditioning. I noticed this. Costly or not?  They didn’t mention how come would this project cost and once built how much would it really save us.
