Inventions by Doug Heffron >
Over the years Doug Heffron has not only thought of cools things to invent he has made them come to life. Doug first made headlines in the 70s with a lawn mower that mows the lawn by its self. Then years later he made more headlines with a car that could achieve 75 miles per gallon. Doug has many inventions that he'd like to share and we will continue to list them as often as we can.
