Retired 3M electrical engineer Bob Nepper, 82, has a garage in his North St. Paul, Minnesota home filled with devices and tools he has designed and built over the years. Much of his work has been focused on water pasteurization. This is a graphic showing how his Solar Pasteurizer panels work. They are in storage in the garage. They proved too expensive to manufacture.
