Wannalancit Mill

As you may or may not know, Nexenta has a small office in Massachusetts, and so I end up in Wikipedia article: Lowell a couple of times a week. Lowell is a decent size city with a history of textile production. As a result, the city is peppered with old mills, most of which have been converted to office and apartment buildings and a couple serve as museums.

The Wannalancit mill is one of the mills that ended up turning into an office building. (It is connected to the adjacent Suffolk mill so I often forget that technically they are separate buildings. You’ve been warned.)

The thing that makes this mill more interesting is that the National Park Service maintains an operational water turbine in the basement. The turbine turns a large flywheel (I am guessing it is about 5 m in diameter).

The turbine itself is in the “basement” along with other goodies. The basement is not very well lit, but the D750 performed quite well even at ISO 5000–8000.

The turbine is geared to the flywheel.

Finally, here is the turbine (inside the red-brown metal object in the background) and the governor (green machine in the foreground) controlling the amount of water entering the turbine and therefore the amount of energy getting stored in the flywheel.

The park service shows up in the mornings to “turn-on” the turbine.

A close-up of the governor:

The table on the left was used for repairing of the 2 cm thick leather belts. I got the impression that the four section cabinet housed containers of oil used to lubricate various parts around the mill.

There are more than three times as many photos in the full gallery. Enjoy!
