ABSTRACT:
A turbine wheel having a central hollow cylindrical water tight shell is encased in a closely fitting cylindrical housing filled with water. The circumference of the wheel carries a plurality of chambers defined by vanes, each vane having a radial flat portion for propelling water tangentially in the direction of rotation of the wheel. Gas is injected near the bottom of the wheel. The buoyant force of trapped gas in the chambers imparts rotation to the wheel, and water displaced by the injected gas circulates in the region between the ends of the vanes and the housing. An external conduit may facilitate efficient replacement by receiving some of the displaced water near the bottom and reintroducing it near the top of the housing.
