Air conditioning could be replaced with mirrors


Scientists have developed a mirror that could see air conditioning units becoming obsolete. Placed on the roof of buildings, the mirrors are designed to reflect light and heat back into the subzero temperatures of space.The researchers believe that the mirrors could dramatically reduce the amount of commercial energy used by business and shopping centres to keep their buildings cool.In the US, around 15% of energy used in commercial buildings goes towards air conditioning, but the scientists are optimistic that in some cases the mirrors could completely remove the need for additional cooling.
