Joe and Allan start off with a salute to the battery, past, present, and future. They cover topics from the storage of mechanical energy to the future of nuclear diamonds. Next, they explore 30 Years of Stupid with a fence system built out of raw (untreated) wood. Joe triggers Allan with a news article about people replacing their lawns with astro-turf. They wrap up by talking about the 1983 World’s Fair in Chicago and its lasting effect present today.
