I know Flint has enough real worries without having to deal with hypothetical problems. But what happens if the city, in its zeal to downsize, overdoes it? Then, when the Flint economy finally blossoms, we'll be left with a housing shortage. (Let's not speculate on what will prompt Flint's economic miracle; I'm not that much of a visionary.) People from the southwest might flood Flint when their water supply dries up, along with their jobs. If that ever happens, inflatable buildings may be the answer.
A Daily Dose of Architecture has a nice overview of bulbous inflatable structures that bring back memories of John Travolta's 1976 made-for-TV classic The Boy in the Plastic Bubble. At least we have one of the potential problems of an economic boom solved.
