1. A fluid turbine comprising:
a hub; and
a rotor segment configured to couple to the hub, the rotor segment comprising:
a blade piece having a first main body and a first cavity extending into the first main body;
a support arm piece having a second main body and a second cavity extending into the second main body; and
a connector configured to adjoin the blade piece and the support arm piece at an orthogonal angle, the connector including a first portion defining a first length and a first cross-sectional area having a first width and a first height, both measured in a respective direction orthogonal to the first length and to each other, the first portion at least partially located within the first cavity of the blade piece, and a second portion defining a second length and a second cross-sectional area having a second width and a second height, both measured in a respective direction orthogonal to the second length and to each other, the second portion at least partially located within the second cavity of the support arm piece, wherein the first length is greater than the first width and the first height, wherein the second length is greater than the second width and the second height, and wherein the first length is measured in a direction orthogonal to the second length.
