turbine - turbine - History of water turbine technology: Experiments on the mechanics of reaction wheels conducted by the Swiss mathematician Leonhard Euler and his son Albert in the 1750s found application about 75 years later. In 1826 Jean-Victor Poncelet of France proposed the idea of an inward-flowing radial turbine, the direct precursor of the modern water turbine.
Like vertical mills, there's a certain amount of flexibility in the beds themselves. Some mill beds will move along one axis only, others can move on more than one. The more movement, the more flexibility – but increased movement does somewhat limit the size of the piece to be milled. Horizontal mills excel at jobs requiring multiple cuts ...

Looking downward from the top, a turbine with a Savonius rotor would look like two spoons facing opposite directions and linked at the center to the rotor axis (creating an 'S' shape in cross section (Fig. 20.14)).Due to their curvature, the drag of the concave surface is higher than the convex surface, forcing the rotor to turn when the cups are exposed to wind (Mathew, 2006).

The challenge in the 1920's was to design a mill that combined the high capacity of the pendulum mill with the smooth running of the Maxecon mill. The solution was the very first Loesche mill, patented in 1927. It featured a rotating grinding track that used centrifugal force to push the grinding stock outwards from the centre of the mill.
America's first saw-mill was built at the Falls of Piscatauqua, on the line between Maine and New Hampshire, in 1634. Unauthenticated records, however, claim that as early as 1633 several mills were operating in New York State. A mill in Sweden was erected in …
The vertical water wheel was born somewhere in the Middle East during the first century BC, as suggested by the earliest textual mention by Strabo of a water mill in Mithridate's palace in Cabeira (north of present-day Turkey). Water wheels further developed to a large extent in the empires of Rome and of China during the first to third ...
