De Borgmolen is a smock mill in Grou, Friesland, Netherlands which was built in 2008. Although not in full working order, it can turn in the wind. It is listed as a Rijksmonument, number 22916.[1]

History

De Borgmolen was originally built in 1895 to drain the De Nije Borgkrite polder. It was worked until 1952 when a windmotor replaced it. In 1954, an electric motor took over. In 1955, the mill was advertised for sale to be demolished. The local council offered the Province a 20% subsidy towards the cost of buying and restoring the mill. It cost ƒ3,900 to restore the mill, which is now owned by the Gemeente Boarnsterhim. A restoration of the mill was undertaken in 1975.[2] The mill suffered from subsidence and the sails were removed in October 2003. It was decided to restore the mill at a new location, and it was dismantled in February 2008.[3] The mill was moved 200 metres (220 yd) to the Biggemeer.[4] it was officially opened on 16 October 2008.[3]

Description

De Borgmolen is what the Dutch describe as an grondzeiler. It is a smock mill on a single-storey brick base. The mill is winded by tailpole and winch. The smock and cap are thatched. The sails are Common sails.[2] They have a span of 14.70 metres (48 ft 3 in).[3] The sails are carried on a wooden windshaft. The windshaft also carries the brake wheel which has 54 cogs. This drives the wallower (25 cogs) at the top of the upright shaft. At the bottom of the upright shaft, the crown wheel, which has 33 cogs formerly drove a wooden Archimedes' screw, which is now missing.[2]

gollark: Not really. Those particular implementations were in C. If C were replaced with another language, similar things would probably exist if there was demand.

gollark: Those could exist without C however.

gollark: I doubt it's a *likely* race condition, but I would like to avoid it.

gollark: I'm pretty sure that the solution to this in C would just be to have race conditions and not notice.

gollark: I was trying to look at how other IRCds solve this, but they're all just tens of thousands of lines of incomprehensible C which probably still contain race conditions, or miniircd, which as far as I can tell just ignores the problem.
