Liquid wheels continued to be burned so you’re able to and from Commercial Trend since the a source of energy to have textile mills and you may almost every other factories, however, were fundamentally supplanted by vapor energy. Liquid mills had been usually included in combination having dams to be hired and increase the interest rate of the liquids.
