In his stories from the duck universe Carl Barks both mentioned and drew countless inventions. Some of them were just mentioned briefly, some were drawn modestly in the background, while others were substantial to the stories' plots. The sub-pages will give examples from the latter group only, and there are a great many of very diverse inventions to choose from, because Barks made many stories where inventions played an important part. Not all together surprising, because he always had a secret dream of becoming a real inventor of different gadgets!
As we all know, Barks never came around to pursue this dream, and instead he channelled some of his ideas out through one of his characters, the ingenious Gyro Gearloose (commonly known as Inventor of Anything), and seeing his inventions we have no reason to doubt the validity of this impressive title. The sub-pages will offer examples of some of his more spectacular realistic and unrealistic inventions, but Barks did not stop there. Through the years he allowed many other inventors from the duck universe to present their inventions as well, and a few of these inventive people are also credited in the sub-pages.

A great many inventions are mentioned in the stories, but the examples only include the ones that are crucial to the plots. Also, it is important to know that the comments primarily mention the inventions as they were known - or not known - at the time of the individual stories.
