Before there was steampunk....

...there was waterpunk!

Here is an example: the Upper Mill* in Milford, Pennsylvania:



I tried to take a movie of the wheels in action, but I haven't spent a lot of time using the movie function of my camera so it didn't turn out so good. I'll try again later in the week and see what I can get for you.

*Strictly speaking, this mill postdates the advent of steam power. But it didn't use steam power; it used unheated water power. Which is waterpunk, as far as I'm concerned. I think I feel a story coming on.
