Patent abstract

A turbine (5) having at least two sets of co-axially mounted, rotatable blades (10, 15) arranged so that one set cannot eclipse another. Preferably, the sets of blades (10, 15) are contra-rotatable. Each set of blades (10, 15) may be operable to extract similar amounts of energy, thereby to minimise the net reactive torque.
