HALES WATER TURBINES
Producing Electricity From Flowing Water
The Hales Turbine has a unique design that makes it highly efficient in slow-flow waters. It has a vertical axis (shaft). The flowing water pushes against the blades, causing the discs to rotate. That rotation turns the shaft, which drives the generator mounted at the top of it.

The image shows an early version of the device.
Most significantly, each blade is pivoted at the outer rim so that, at the start of the ‘passive’ half of its rotation about the axis, the blade swings outwards from the rim and aligns itself with the flow, thereby minimising drag. Having returned to the 'active' phase, the blade is held securely in position by a central Drive Pin, so that it turns the discs - which, in turn, drive the shaft.

The video shows the Hales Turbine in the flowing water of a test tank. It is submerged only partly so that it can be clearly seen. In practical applications, the turbine is fully submerged in the water.
