Abstract

An apparatus may include a cage that rotates around a cage axis and a turbine located at an end of the cage and rotating around a turbine axis. A turbine blade may have an adaptable shape. A frame of the turbine blade may have a first frame portion that pivots relative to the second frame portion. The curvature of the turbine blade may be controlled by shortening a connection while concurrently lengthening another connection. Controllers may control the rotation of the cage(s) and/or turbine(s) based on a speed, a direction, a velocity, an acceleration of wind, and/or a load carried by the apparatus. The apparatus may be a Savonius machine. Rotation of the cage(s) and/or turbine(s) may induce a Magnus effect. A seat and user controls near the seat may be included. The user controls may control the rotation of the cage(s) and/or turbine(s).

Claims

1. An apparatus comprising:

a cage configured to rotate around a cage axis, wherein the rotation of the cape around the cape axis causes a lift of the apparatus above the around;

a turbine located at and coupled to an end of the cage, wherein the turbine rotates around a turbine axis different from the cage axis, and wherein the turbine comprises a turbine blade having an adaptable shape and comprising;

a frame including a first frame portion and a second frame portion coupled to the first frame portion, and wherein the first frame portion pivots relative to the second frame portion,

a first connection between a first side of an end of the frame and a center region of the frame; and

a second connection between a second side of the first end of the frame and the center region of the frame; and

wherein the adaptable shape of the turbine blade conforms to a substantially flat shape and to a curvature shape by adjusting, maintaining, shortening, or lengthening lengths of the first connection and the second connection.

2. The apparatus of claim 1, wherein the first frame portion further pivots relative to the second frame portion when the first connection or the second connection is shortened or lengthened.

3. The apparatus of claim 1, wherein the adaptable shape of the turbine blade comprises the substantially flat shape when a length of the first connection is similar to a length of the second connection, and the curvature shape when the length of the first connection is different from the length of the second connection.

4. The apparatus of claim 1, wherein by shortening the first connection while concurrently lengthening the second connection or by shortening the second connection while concurrently lengthening the first connection forms the curvature shape.

5. The apparatus of claim 1, wherein the rotation of the cage around the cage axis is inhibited when the apparatus is in a first mode, and wherein the rotation of the turbine around the turbine axis is allowed when the apparatus is in the first mode.

6. The apparatus of claim 1, wherein the rotation of the cage around the cage axis is allowed when the apparatus is in a second mode, and wherein the adaptable shape of the turbine dynamically changes when the apparatus is in the second mode.

7. The apparatus of claim 1, wherein the rotation of the cage around the cage axis is inhibited when the apparatus is in a third mode, and wherein the turbine blade remains in a horizontal position relative to ground and the rotation of the turbine around the turbine axis is inhibited when the apparatus is in the third mode.

8. The apparatus of claim 1, further comprising a plurality of cages and a plurality of turbines, wherein the blades of the turbine extend substantially horizontally relative to the ground.

9. The apparatus of claim 1, wherein the rotation of the turbine around the turbine axis-lifts the apparatus above the ground.

10. The apparatus of claim 1, further comprising a motor to convert a kinetic energy from the rotation of the cage around the cage axis to electric energy or convert a kinetic energy from the rotation of the turbine around the turbine axis to electric energy.

11. The apparatus of claim 1 further comprising a seat, and where the adaptive shape of the turbine blades is responsive to a user'"'"'s inputs.

12. The apparatus of claim 1, wherein the turbine blade is pulled along a longitudinal axis of the turbine blade such that at least a distance between a motor of the cage is extended or a distance between arm connectors on each cage axis is extended.

13. An apparatus comprising:

a cage which rotate around a cage axis, wherein the rotation of the cage around the cage axis induces a lift of the apparatus above the ground;

a plurality of turbines located within the cage, wherein each turbine rotates around a respective turbine axis different from the cage axis, and wherein each turbine comprises a turbine blade having an adaptable shape and comprising;

a first connection between a first end of the turbine and a center region of the turbine; and

a second connection between a second end of the turbine and the center region of the turbine; and

the adaptable shape of the blade changes from a flat shape to a curved shape by adjusting at least one of the first connection or second connection.

14. The apparatus of claim 13, wherein the turbine blade comprises a frame having a first frame portion and a second frame portion coupled to the first frame portion, and wherein the first frame portion pivots relative to the second frame portion when the first connection or the second connection is shortened or lengthened.

15. The apparatus of claim 13, wherein the rotation of the cage around the cage axis is inhibited when the apparatus is in a first mode, and wherein the rotation of the turbine around the turbine axis is allowed when the apparatus is in the first mode.

16. The apparatus of claim 13, wherein the rotation of the cage around the cage axis is allowed when the apparatus is in a second mode, and wherein the adaptable shape of the turbine dynamically changes when the apparatus is in the second mode.

17. The apparatus of claim 13, wherein the rotation of the cage around the cage axis is inhibited when the apparatus is in a third mode, and wherein the turbine blade remains in a horizontal position relative to ground and rotation of the turbine around the turbine axis is inhibited when the apparatus is in the third mode.
