Abstract

A bladeless wind turbine apparatus includes a mast. The bladeless wind turbine apparatus includes protrusions on a surface of the mast. The bladeless wind turbine apparatus includes a base structure. The bladeless wind turbine apparatus includes springs connecting to the base structure. The bladeless wind turbine apparatus includes at least one magnet. The bladeless wind turbine apparatus includes at least one coil magnetic wiring.

Claims (50)

1 . A bladeless wind turbine apparatus, comprising:

a mast, wherein the mast is configured to oscillate;

protrusions on a surface of the mast;

a base structure, wherein the base structure includes:

a center structure,

a top structure,

a bottom structure, and

multiple legs, wherein the multiple legs are parallel to the center structure;

a first connector, wherein:

the center structure of the base structure is connected to a bottom part of the first connector and the mast is connected to a top part of the first connector;

springs, wherein the springs connect to the base structure, wherein:

a top edge of at least one of the springs is attached to the center structure, a bottom edge of the at least one of the springs is attached to the bottom structure of the base structure at a location between two of the multiple legs, and

the at least one of the springs is at an angle less than 90 degrees based on its attached to the bottom structure and the center structure of the base structure;

at least one magnet, wherein the at least one magnet is attached to the first connector; and

at least one magnetic coil wiring, wherein:

the at least one coil magnetic wiring is parallel to the least one magnet, and the at least magnetic coil wiring base is attached to the base structure.

2 . The bladeless wind turbine apparatus of claim 1 , wherein the mast has a top surface and a bottom surface.

3 . The bladeless wind turbine apparatus of claim 2 , wherein the top surface has a larger circumference than the bottom surface.

4 . The bladeless wind turbine apparatus of claim 1 , wherein the base structure has appurtenances on each side.

5 . The bladeless wind turbine apparatus of claim 1 , wherein the protrusions are prism shaped.

6 . A method, comprising:

receiving, by a bladeless wind turbine system, wind, wherein:

the bladeless wind turbine system has a mast that oscillates,

the bladeless wind turbine system has protrusions that increases oscillations; and

generating, by the bladeless wind turbine system, power based on the oscillations, wherein the generating the power is based on:

at least one magnet and at least one magnetic coil wiring, and

springs connected to a base structure wherein:

the base structure includes:

a center structure,

a top structure,

a bottom structure, and

multiple legs, wherein the multiple legs are parallel to the center structure; and the bladeless wind turbine system further includes:

a first connector, wherein:

 the center structure of the base structure is connected to a bottom part of the first connector and the mast is connected to a top part of the first connector, and

 the springs are configured to connect to the base structure,

wherein:

 a top edge of at least one of the springs is attached to the center structure,

 a bottom edge of the at least one of the springs is attached to the bottom structure of the base structure at a location between two of the multiple legs, and

 the at least one of the springs is at an angle less than 90 degrees based on its attached to the bottom structure and the center structure of the base structure;

the at least one magnet is attached to the first connector, wherein:

the at least one coil magnetic wiring is parallel to the least one magnet, and

the at least magnetic coil wiring base is attached to the base structure.

7 . The method of claim 6 , wherein the mast has a top surface that has a circumference that is greater than a bottom surface of the mast.

8 . The method of claim 6 , wherein the protrusions are prism shaped.

9 . The bladeless wind turbine apparatus of claim 8 , wherein:

a horizontal distance between a first protrusion, of the protrusions, and a second protrusion, of the protrusions, is less than a vertical distance between the first protrusion and a third protrusion of the protrusions.

10 . The apparatus of claim 1 , wherein the springs cause a vortex shedding frequency to be equivalent to the frequency of the bladeless wind turbine.

11 . The apparatus of claim 1 , wherein one of the protrusions has its top edge parallel to the surface of the mast and another one of the protrusions has its top edge perpendicular to the surface of the mast.

12 . The method of claim 7 , wherein the generating the power is based on the springs which are configured to a cause a vortex shedding frequency to be equivalent to the frequency of the bladeless wind turbine.

13 . The method of claim 6 , wherein one of the protrusions has its top edge parallel to the surface of the mast and another one of the protrusions has its top edge perpendicular to the surface of the mast.
