The rotor assembly includes a plurality of rotor blades having rotor tips at their outermost ends which define a rotor M tip sweep circumference. A duct assembly at least partially surrounds said rotor tip sweep circumference and a base platform supports IN the ducted wind turbine. The duct assembly is mounted on the base platform by way of a weathervane bearing arrangement such that 0 -....... the duct assembly may weathervane around the turbine rotor assembly in response to changes in wind direction. A semi-submersible Ot support platform, wave energy capture apparatus, torsional bearing mechanism and a latticework wind turbine tower associated with 1-1 c:: ) the ducted wind turbine are also provided. ei O [Continued on next page] WO 2018/073609 Al MIDEDIMOMOIDEIREEMOOMEIIIIMINNEHMEHOIS OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
