Flow conversion turbines and assemblies

A conversion assembly comprising a particular number of multiple double turbines arranged along a shared axis of rotation, each double turbine respectively comprising:

• a rotatable deflector disc including a first base plate and a second base plate facing opposing directions along the axis of rotation;
• a first plural number of first vanes each pivotally mounted on the first base plate and uniformly spaced around the axis of rotation by a vane spacing angle;
• a second plural number of second vanes each pivotally mounted on the second base plate, and uniformly spaced around the axis of rotation by the vane spacing angle, the second plural number being equivalent to the first plural number;
• and
• wherein each first vane is angularly positioned with respect to the axis of rotation as between two second vanes,
• wherein the multiple double turbines are arranged with a progressive helical twist such that each double turbine is offset from at least one adjacent double turbine by a common twist angle with respect to the axis of rotation.

A conversion assembly for converting kinetic energy in a fluid flow to electrical energy, the conversion assembly comprising:

• a particular number of multiple double turbines mounted along a shared rotatable axle defining an axis of rotation, each double turbine respectively comprising:
• a rotatable deflector disc mounted on the shared rotatable axle, the rotatable deflector disc including a first base plate and a second base plate facing opposing directions along the axis of rotation;
• a first plural number of first vanes each pivotally mounted on the first base plate and uniformly spaced around the axis of rotation by a vane spacing angle;
• a second plural number of second vanes each pivotally mounted on the second base plate, and uniformly spaced around the axis of rotation by the vane spacing angle, the second plural number being equivalent to the first plural number;
• and
• wherein each first vane is angularly positioned with respect to the axis of rotation as between two second vanes,
• wherein the multiple double turbines are arranged with a progressive helical twist such that each double turbine is offset from at least one adjacent double turbine by a common twist angle with respect to the axis of rotation;
• and
• a generator coupled to the shared rotatable axle and operative to generate electrical energy upon rotation of the axle, the generator in electrical communication with at least one of a battery, an electrically powered device, and a land-based facility;
• wherein at least the multiple double turbines are disposed in a fluid flow engaging the first vanes and the second vanes of each double turbine causing rotation of the axle and conversion of kinetic energy in the fluid flow into electrical energy by the generator.
