## Abstract

A turbine system includes a shaft extending along an axis. A first spoke has a first end, attached to the shaft, and a second end. A second spoke has a first end, attached to the shaft, and a second end. A third spoke has a first end, attached to the shaft, and a second end. A turbine blade is attached to the second end of the first spoke, the second end of the second spoke, and the second end of the third spoke. The turbine blade extends continuously circumferentially about the axis. The turbine blade is spaced a distance apart from the axis and in non-contact with the shaft.

## Claims

### Claim 1

A turbine system comprising:
a shaft extending along an axis;
a first spoke having a first end, attached to the shaft, and a second end;
a second spoke having a first end, attached to the shaft, and a second end;
a third spoke having a first end, attached to the shaft, and a second end; and
a turbine blade attached to the second end of the first spoke, the second end of the second spoke, and the second end of the third spoke, the turbine blade extending continuously circumferentially about the axis, the turbine blade spaced a distance apart from the axis and in non-contact with the shaft.

### Claim 2 (depends on 1)

The turbine system of claim 1, wherein a length of the turbine blade along the axis is greater than a thickness of the turbine blade perpendicular to the axis.

### Claim 3 (depends on 1)

The turbine system of claim 1, wherein the turbine blade extends circumferentially about the axis while being spaced a non-constant distance from the axis.

### Claim 4 (depends on 1)

The turbine system of claim 1, wherein the turbine blade further comprises:
a first peak disposed between the first spoke and the second spoke;
a second peak disposed between the second spoke and the third spoke; and
a third peak disposed between the third spoke and the first spoke, wherein
the first peak, the second peak, and the third peak are spaced equally around the circumference of the shaft.

### Claim 5 (depends on 4)

The turbine system of claim 4, wherein the first peak and the second peak are spaced apart by between about 100 degrees and about 140 degrees.

### Claim 6 (depends on 5)

The turbine system of claim 5, wherein the first peak and the second peak are spaced apart by about 120 degrees.

### Claim 7 (depends on 1)

The turbine system of claim 1, wherein the turbine blade further comprises:
a first peak;
a second peak;
a third peak;
a first valley;
a second valley; and
a third valley, wherein each of the first peak, the second peak, and the third peak are bordered by at least one of the first valley, the second valley, and the third valley.

### Claim 8 (depends on 1)

The turbine system of claim 1, wherein the turbine blade further comprises an inner face and an outer face, the inner face and the outer face alternate the directions in which they face.

### Claim 9 (depends on 8)

The turbine system of claim 8, wherein the turbine blade further comprises an inner side and an outer side, wherein the inner face faces toward the first side and the outer face faces the second side at a first location on the turbine blade, and the inner face faces toward the second side and the outer face faces the first side at a second location.

### Claim 10 (depends on 9)

The turbine system of claim 9, wherein the axis extends from the first side toward the second side intersects the outer face before intersecting the inner face.

### Claim 11 (depends on 9)

The turbine system of claim 9, wherein the inner face is oriented to face toward the axis while the outer face is oriented to face away from the axis.

### Claim 12

A turbine system comprising:
a shaft extending along an axis;
at least one spoke having a first end, attached to the shaft, and a second end; and
a turbine blade attached to the second end of the at least one spoke, the turbine blade extending continuously circumferentially about the axis, a first portion of the turbine blade spaced a first distance from the axis, a second portion of the turbine blade spaced a second distance from the axis that is different than the first distance.

### Claim 13

A turbine system comprising:
a shaft extending along an axis;
at least one spoke having a first end, attached to the shaft, and a second end; and
a turbine blade attached to the second end of the at least one spoke, the turbine blade extending continuously circumferentially about the axis, the turbine blade comprising:
an outer face oriented away from the axis; and
an inner face oriented towards the axis;
wherein at a first location of the turbine blade, the inner face faces a first direction along the axis and the outer face faces a second direction along the axis, at a second location of the turbine blade, the inner face faces the second direction along the axis and the outer face faces the first direction along the axis.
