In the 1970s the Soviet government, built a series of lighthouses around the Arctic Circle to aid in navigation. Since these were built in the most godforsaken parts of Siberia, they were not only automated, but nuclear powered. After the collapse of the Soviet Union, people began to strip them for metal, including the radiation shielding.
When I read about this. I couldn’t help but think of Russia’s floating nuclear power plants, perhaps plying the seas past the lighthouses.
But, what I really think of when I see the sea ravaged edifice is something out of a Life Without People episode. Nuclear powered autonomous lighthouses guiding nuclear powered autonomous ships to ports, where where they are loaded with ore from continuous conveyors, that are supplied by autonomous freight trains, until the day that there’s just nothing left to load on the trains, or on the ships, and the entire system shuts down and rusts.
