The Happiness Machine (2019)

Carl grew up a sharecropper on 22 acres in rural Iowa, which he now calls The Promised Land. A philosopher, inventor, and farmer, he shares with us the deeply intricate workings of his projects, (including a full span bridge he built with his hands), how they are connected to the land which was given to him as a promise, and what he hopes to pass on to his children as the gift of place.
