The Engines of Our Ingenuity
The series tells the story of human invention and creativity in 3-1/2 minute essays. The stories center upon engineering/technology, but they venture freely into mathematics, science, literature, medicine, music, art and other areas. The program thus reveals much of the cultural history that is formed by technology and other creative enterprises; and it reveals how culture in turn shapes technology and science. The program airs nationally on many public radio stations, as well as other outlets.
At any one time, the program is likely to be airing on 40 or so stations in the United States, as well as such specialized outlets as Armed Forces Radio and the International Space Station, and occasional overseas radio. No exact count is possible since the program is made available free of charge and reporting of its use is not enforceable. 
Part of the growing influence of the series has been an initiative to create a Spanish language version of the program, Invenciones de la Inventiva. These are episodes that have been translated into Spanish and are presently airing on station KNTU. 
The Engines of Our Ingenuity website features complete audio for all the episodes of the program, as well as complete illustrated transcripts. It also includes variety of value-added items: related technical papers, books, and other sources. For a complete list of Engines topics, see the list of titles and keywords. 
The Engines of Our Ingenuity was first aired on January 4, 1988. It reached 2970 finished episodes in September, 2014. The series was founded by John H. Lienhard, retired Professor of Mechanical Engineering at the University of Houston, and member of the National Academy of Engineering. The program is presently done by a group of experts in several fields, including Lienhard.
Lienhard has published three books that reflect the content of Engines.
