Abandoned Autonomous Polar Power
English Russia is hosting a fantastic gallery of abandoned Soviet nuclear lighthouses, which were strung in the polar regions off of Russia’s northern coast. A rather Russian-Engrishy description, but you get the idea:
The Communist Party of the Soviet Union decided to build a chain of lighthouses to guide ships finding their way in the dark polar night across uninhabited shores of the Soviet Russian Empire. So it has been done and a series of such lighthouses has been erected. They had to be fully autonomous, because they were situated hundreds and hundreds miles aways from any populated areas. After reviewing different ideas on how to make them work for a years without service and any external power supply, Soviet engineers decided to implement atomic energy to power up those structures. So, special lightweight small atomic reactors were produced in limited series to be delivered to the Polar Circle lands and to be installed on the lighthouses.
