Ralph Waldo Emerson never said “Build a better mousetrap, and the world will beat a path to your door.” The mousetrap that likely inspired the misquote was invented seven years after his death. Unfortunately, many people take it literally. GHPs have all the hallmarks of a better mousetrap: They do the job of heating and cooling a building more efficiently than any other option. Despite the larger up-front cost, they are a mature technology and usually the most economic option for buildings that can accommodate them.
