Jim Laukes is an independent scholar from Chicago, and a friend. He's been making some videos at Solar Park, the neighborhood in Glenview, Illinois, where George Fred Keck designed several solar houses for real estate developer Howard Sloan.
In this clip, Laukes captures Chicago architects Nate Kipnis and Mark Miller in the back yard of the first "solar house"---the Sloan house of 1940. At the beginning they are discussing the possibility of overheating.
