Keeping cool on a hot summer day takes a whole lot of electricity to work the air conditioner, but researchers from the Malaviya National Institute of Technology in India could supply the world with a greener solution thanks to a natural, passive method for keeping indoor environments cool. that system will bring together a wind tower and solar chimney as part of the building’s architecture, where the former provides a draft of air cooled by the stones that

flows through windows upward through the building. that draft will next push the hotter inside air upwards, where it soon after escapes via the chimney’s thermally conducting panels. that solution claims to “lower the inside temperature by about 5 degrees C (9 degrees F)”, which goes a lengthy way in keeping a building or home cool.
