The Cool History of Air Conditioning

Hot enough for you? We can be thankful that we can do something about it, but it hasn't always been this way. In this podcast, Ray Notgrass traces the history of attempts to produce conditioned air, from awnings to fans blowing over ice to the invention of systems that really provided cooler air to homes, businesses, and cars. We hope you enjoy this really cool presentation.
