These include all three variants of the vertical water wheel as well as the horizontal water wheel. [6] Apart from its main use in grinding flour, water-power was also applied to pounding grain, [7] crushing ore, [8] sawing stones [9] and possibly fulling and bellows for iron furnaces. [10]
The estimated cost to build one water wheel is $1.9 million, and the city has yet to meet its goal. Donations from sponsors and partnerships total $1.34 million.
