Willis Carrier

    While watching the film "Nova: Absolute Zero" it was interesting to learn about the historical evolution on the idea of cold. Willis Carrier is known for inventing the first air conditioning machine in 1902. He got the idea while working in a fan warehouse and implemented his idea to help a printing copy keep the ink on the page during a hot Brooklyn day. Now Carrier air conditioning is using CO2 systems that reduce the green house gas admission. The air conditioning system he made was more than just cold, it could also heat and keep a constant humidity.
