NOVELTY - The turbine (200) has a stator (206) comprises first multiple electricity-generating coils (208). A rotor (204) comprises a second multiple electricity-generating magnets (209). The rotor is arranged radially outward of an outer circumferential surface of the stator and configured to rotate around the stator about an axis of rotation. The rotor is a flexible belt structure. A bearing mechanism is configured to support the rotor relative to the stator during rotation of the rotor around the stator.    USE - Hydroelectric turbine used to generate electricity from current in moving surface of water e.g. river or ocean current or other fluid source.    ADVANTAGE - The hydroelectric turbine has a robust configuration that can withstand the strong, intermittent, and turbulent forces e.g. axial and/or radial associated with fluid flow interacting therewith. The turbine is efficiently assembled on-site to reduce the expense of shipping the assembly from a manufacturing plant to the installation location. The energy in a fluid flow can be directly converted to electricity by the use of magnets embedded in a rotor. The rotor is arranged outwardly of the stator can provide for a robust configuration of the turbine, potentially enhancing stability and strength, and reducing the amount of materials used to construct the turbine structure. The forces acting on the rotor are balanced, thus reducing stresses on the rotor and allowing for the use of less material in both the rotor and the blades.
