## Abstract

Aspects of the disclosure include a tidal power generator comprising a first container, at least one second container pivotably coupled to the first container, a frame pivotably coupled to the first container, a first valve, associated with the first container, configured to selectively control ingress of a first volume of a first fluid into the first container, and a second valve, associated with the first container, configured to selectively control egress of a second volume of the first fluid out of the first container.

## Claims

### Claim 1

A tidal power generator comprising:
a first container;
a shaft;
a second container coupled to a first side of the first container via the shaft and a third container coupled to a second side of the first container via the shaft, the second side being opposite the first side, and the second container and the third container being pivotably coupled to the first container;
a frame pivotably coupled to the first container;
a first valve, associated with the first container, configured to selectively control ingress of a first volume of a first fluid into the first container; and
a second valve, associated with the first container, configured to selectively control egress of a second volume of the first fluid out of the first container.

### Claim 2 (depends on 1)

The tidal power generator of claim 1, wherein the second container is fluidically decoupled from the third container.

### Claim 3 (depends on 1)

The tidal power generator of claim 1, wherein the first container is fluidically decoupled from the second container and from the third container.

### Claim 4 (depends on 1)

The tidal power generator of claim 1, wherein the tidal power generator is disposed in a body of the first fluid, the body of the first fluid having a high fluid level and a low fluid level.

### Claim 5 (depends on 4)

The tidal power generator of claim 4, wherein the tidal power generator is configured to raise the first volume of the first fluid above the high fluid level.

### Claim 6 (depends on 1)

The tidal power generator of claim 1, wherein the second volume of the first fluid is provided to one or more electrical generators to drive the one or more electrical generators.

### Claim 7 (depends on 1)

The tidal power generator of claim 1, wherein the frame is configured to be coupled to a fixed plane.

### Claim 8 (depends on 1)

The tidal power generator of claim 1, wherein each of the second container and the third container includes a second fluid having a density less than a density of the first fluid.

### Claim 9 (depends on 8)

The tidal power generator of claim 8, wherein each of the second container and the third container is hermetically sealed.

### Claim 10 (depends on 1)

The tidal power generator of claim 1, further comprising a screen coupled to the first valve, the screen being configured to prevent unwanted materials from entering the first valve.

### Claim 11

A tidal power generator comprising:
a first container;
at least one second container pivotably coupled to the first container;
a frame pivotably coupled to the first container;
a first valve, associated with the first container, configured to selectively control ingress of a first volume of a first fluid into the first container; and
a second valve, associated with the first container, configured to selectively control egress of a second volume of the first fluid out of the first container,
wherein the tidal power generator is disposed in a body of the first fluid, the body of the first fluid having a high fluid level and a low fluid level, and
wherein the tidal power generator is configured to raise the first volume of the first fluid above the high fluid level.

### Claim 12 (depends on 11)

The tidal power generator of claim 11, wherein the first container is fluidically decoupled from the at least one second container.

### Claim 13 (depends on 11)

The tidal power generator of claim 11, wherein the second volume of the first fluid is provided to one or more electrical generators to drive the one or more electrical generators.

### Claim 14 (depends on 11)

The tidal power generator of claim 11, wherein the at least one second container includes a second fluid having a density less than a density of the first fluid.

### Claim 15 (depends on 11)

The tidal power generator of claim 11, wherein the at least one second container includes a second container and a third container, the second container being coupled to a first side of the first container and the third container being coupled to a second side of the first container.
