  4. Small Michell (Banki) Turbine

    1980-01-01 The Michell or Banki turbine is a relatively easy to build and highly efficient means of harnessing a small stream to provide enough power to generate electricity or drive different types of mechanical devices. The turbine consists of two main parts - the runner, or wheel, and the nozzle. Curved...
