Title: Dual hydroturbine unit

Abstract: An environmentally non-intrusive multiple turbine unit for adjustable deployment in water. The turbines are captured in a shroud having an integrally formed augmentor ring and ballasting member to improve efficiency. The multiple turbine arrangement effectively counteracts the rotational counter-torque of individual turbines, thereby enabling stable deployment of the unit without requiring rigid stabilizing structures.
