7. Garbage chute, former USSR
How does one turn a cool idea into a nightmare? It’s very simple — create a garbage chute. The instant waste disposal device was first designed for a house in Vladivostok back in 1938. At first, the chute outlets were located inside of the actual apartments, but later they were moved to be in a central location on each floor of the apartment block for sanitary purposes. However, that didn’t help either. Today, residents of apartment buildings ask management organizations to weld waste chutes closed because of the unsanitary conditions they create.
