Michael Mulligan has built a career in engineering while pursuing hobbies centered around the reproduction of American frontier artifacts such as the Kentucky rifle and, above all, the log cabin. He began more than 30 years ago by building a full-size home from locally cut pine trees and went on to construct a series of smaller log buildings, including vacation and hunting/camping cabins. Mulligan is currently involved in the research and development of improved ways of supplying remote locations with economical and reliable solar electric power.
