Patent ID: 8482142

Claim:
A power generation system, comprising: a fluid turbine, the turbine comprising: a mixer shroud enclosing a rotor/stator assembly, the mixer shroud comprising a ring of mixer lobes located along a downstream end and downstream of the rotor/stator assembly; the rotor/stator assembly including a rotor and a stator, the stator having a phase winding, the rotor having a central ring, an outer ring, a plurality of rotor blades extending between the central ring and the outer ring, and a plurality of permanent magnets on the outer ring, wherein the mixer shroud includes a ring airfoil encircling the outer ring of the rotor and the plurality of rotor blades, and wherein the ring airfoil includes the stator; a center body extending through the central ring to support the rotor and configured to remain in a fixed position with respect to the ring airfoil; and an ultracapacitor bank electrically connected to the fluid turbine.
