## Abstract

Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines.

## Claims

### Claim 1

A wind turbine, comprising:
a rotating main body with a front and a rear, wherein the main body has a hollow interior that narrows in diameter from the front to the rear;
an inlet opening in the front of the main body; and
one or more outlet openings in the rear of the main body.

### Claim 2 (depends on 1)

The wind turbine of claim 1, wherein at least one of said one or more outlet openings comprises an outlet nozzle extending at an angle from the main body.

### Claim 3 (depends on 2)

The wind turbine of claim 2, wherein said outlet nozzle is in the shape of an aerodynamic foil.

### Claim 4 (depends on 1)

The wind turbine of claim 1, wherein the hollow interior of the main body is adjustable.

### Claim 5 (depends on 2)

The wind turbine of claim 2, wherein said outlet nozzle is adjustable.

### Claim 6

An energy-generating device, comprising:
a rotating main body with a front and a rear, wherein the main body has a hollow interior that narrows in diameter from the front to the rear;
an inlet opening in the front of the main body, said inlet opening adapted to collect fluid and direct it to the hollow interior; and
at least one outlet opening in the rear of the main body, said outlet opening adapted to expel collected fluid from the hollow interior.

### Claim 7 (depends on 6)

The device of claim 6, wherein the fluid comprises air or a gas.

### Claim 8 (depends on 6)

The device of claim 6, wherein the fluid comprises water or a liquid.

### Claim 9 (depends on 6)

The device of claim 6, wherein said at least one outlet opening comprises an outlet nozzle extending at an angle from the main body.

### Claim 10 (depends on 9)

The device of claim 9, wherein said outlet nozzle is in the shape of an aerodynamic foil.

### Claim 11 (depends on 6)

The device of claim 6, wherein the hollow interior is adjustable.

### Claim 12 (depends on 9)

The device of claim 9, wherein said outlet nozzle is adjustable.

### Claim 13 (depends on 6)

The device of claim 6, further comprising an inlet funnel adapted to direct fluid into the inlet opening.

### Claim 14

A device for generating energy, comprising:
an aeolipile with an axis of rotation, and one or more conduits, each of said one or more conduits having an intake end and an ejection end;
wherein each of said one or more conduits narrows in diameter from the intake end to the ejection end;
wherein the intake end of each of said one or more conduits is adapted to collect fluid from a fluid flow and direct it through the conduit to the corresponding ejection end.

### Claim 15 (depends on 14)

The device of claim 14, further comprising an eductor-ejector located between the intake end and the ejection end of the said one or more conduits, said eductor-ejector adapted to draw additional fluid into the one or more conduits.

### Claim 16 (depends on 14)

The device of claim 14, wherein the fluid is ejected at an angle relative to the axis of rotation.
