Caisson lighthouse

A caisson lighthouse (also referred to as a sparkplug lighthouse, or bug light) is a type of lighthouse whose superstructure rests on a concrete or metal caisson.[1] Caisson lighthouses were developed in the late nineteenth century as a cheaper alternative to screwpile lighthouses. The Caisson design was also more efficient as it could better withstand harsh weather, and were not as fragile. Caisson lighthouses usually have living quarters made of cast iron, although some brick examples are known. The two American nicknames were later coined because of the structure's shape.[1]

gollark: > Collectivization will take place naturally as soon as state coercion is over, the workers themselveswill own their workplaces as the capitalists will no longer have any control over them. This iswhat happened during the Spanish Revolution of 1936, during which workers and farmers seized andmanaged the means of production collectively. For those capitalists who had a good attitude towardsworkers before the revolution, there was also a place - they joined the horizontal labor collectivesUm. This seems optimistic.
gollark: > "Legally anyone can start their own business. Just launch a company!”. These words oftenmentioned by the fans of capitalism are very easy to counter, because they have a huge flaw. Namely,if everyone started a company, who would work for all these companiesThis is a bizarre objection. At the somewhat extreme end, stuff *could* probably still work fine if the majority of people were contracted out for work instead of acting as employees directly.
gollark: The hierarchical direct democracy thing it describes doesn't seem like a very complete or effective coordination mechanism, and it seems like it could easily create unfreedom.
gollark: I disagree with this PDF, for purposes.
gollark: There was that fun time when someone renamed themselves "all active players".
