1. A fluid turbine, comprising:
a shaft configured for vertical orientation, the shaft having at least one opening extending transversely therethrough;
a first blade portion, configured for vertical orientation on a first side of the shaft;
a second blade portion, configured for vertical orientation on a second side of the shaft, opposite the first side;
at least one rod extending through the at least one shaft opening and configured for connection at a first end thereof to the first blade portion, and at a second end thereof to the second blade portion;
at least one reinforcing sleeve extending through the at least one shaft opening and being interposed between the at least one rod and the at least one shaft opening for reinforcing at least one of the shaft, the at least one shaft opening, or the at least one rod against forces exerted by the first blade portion and the second blade portion when fluid impacts the first blade portion and the second blade portion,
wherein the at least one shaft opening includes a plurality of shaft openings, the at least one sleeve includes a plurality of sleeves, and the at least one rod includes a plurality of rods each of the plurality of rods extending through a differing one of the plurality of sleeves and a differing one of the plurality of shaft openings, and wherein the plurality of rods are threaded; and
a plurality of aerodynamic sleeves for covering exposed threaded portions of the plurality of rods.
