- Period of Use: 4500 BCE to Present (some still rarely do use them)
- Made Obsolete By: In-Door Plumbing
While some may not consider the Outhouse a form of technology, it actually was. While an outhouse was a place where people used to go to, well, take care of some “personal waste disposal,” there was some tech in this. Outhouses were relatively useful and could allow a person a room to use the restroom, where they could empty out all waste into a specific area. Some of which would go off into the environment or even early sewer systems.
Plumbing tech like this was great, as humans used to just go in a bucket but it had to eventually be thrown out. Which was often not handled well. Outhouses could prevent this problem, and the several advancements to them were terrific as time went on. However, in the words of one of the Fates from Disney’s Hercules: “in-door plumbing, it’s gonna be big.” She was right, which is why outhouses became one of the world’s obsolete tech products.
