Let's plunge into the past for a couple of minutes and look at examples of short-lived, but at one time very original inventions. 
Their Steve Jobs and Elon Musks lived in all decades and invented many useful and relevant mechanisms, based on what year it was. Many similar gizmos from the past, of course, do not fit into today's realities, instead taking on entertainment properties.

4. Military locators from the First World War
