<p>The invention provides for the generation of electrical power from low head water, such as the flowing water of rivers or the like, the electrical power is generated by passing the water in sequence over flexible bags or membranes to displace air under the flexible bags or membranes. The displacement of the air is utilised for the driving of a power generator such as an air turbine, and smooth power flow is achieved by diverting air displaced from the underside of one membrane into the cavity under the other membrane. The water flows over the membranes in sequence so that a self oscillating system is set up with the air being displaced back and forth from the cavities, and the displacement air being used to drive the air turbine. Preferably a bi-directional air turbine such as a Wells turbine is used.</p> |
