Claim 13:
14. An autonomous turbine generator unit (ATGU), comprising:
a first cross-flow turbine comprising a first plurality of foils spaced apart from a main shaft, the first plurality of foils having pitch that is adjustable under control of a pitch control mechanism;
a second cross-flow turbine comprising a second plurality of foils spaced apart from a second main shaft, the second plurality of foils having pitch that is adjustable under control of a second pitch control mechanism;
a frame supporting the main shaft and enabling rotation of the first cross-flow turbine;
a generator-motor set comprising rotor and stator elements, the rotor element being in rotary communication with the main shaft; and
a gearbox that either:
operates on the first cross-flow turbine; or
the first cross-flow turbine and the second cross-flow turbine.
