Applications
Possible
applications include, but are not limited to, the following:
- Rivers - where damming of the river is impractical
- Rivers or creeks in remote locations
- Irrigation channels
- Tidal channels and estuaries
- Pumping for irrigation or dewatering of marsh land
- Energy recovery from existing hydro schemes
- Energy recovery from urban storm water systems
- Energy recovery in the form of compressed air or pumped
refrigerant
The turbine is
suitable for any anchored or tethered raft applications.
As the paddle wheels are rotating in the horizontal plane, rather than the vertical, it is a simple matter to have the whole unit sitting on a small anchored raft, with a power cable running to shore.
In this application it is irrelevant that the raft might twist or rise with the current or tide, unlike a vertical plane paddle wheel.
Alternatively, the turbine could be totally submerged (and less open to vandalism) with its energy transmission line running back up the anchoring cable.

Future Testing
It is proposed to
carry out further testing to determine the precise speed/torque
characteristics of the turbine at various water velocities.
Tests in a marine environment, with tidal flows, are also proposed.
Following the second phase of testing, it is proposed to establish a computer model to accurately forecast the fluid flow pattern through the unit. This would be useful for optimising the design for the specific conditions and for designing and building larger turbines.
