Abstract

An energy facility that generates energy using ballistic optimized hydro-electricity. The facility sends a plurality of specialized balls from a lower storage reservoir to an upper storage reservoir. The balls fall through a drop-down system and into a power generation system with a generator and a turbine. Ballistic impacts of the balls on the turbine generate electricity before the balls are returned to the lower storage reservoir.

Claims (25)

1 . An energy facility comprising:

a plurality of balls, each ball comprising (1) an outer layer with (2) at least two inner layers that are sequentially disposed and separated from one another by a divider (3) an endosome layer within the at least two inner layers, (4) a payload container disposed within the at least two inner layers and (5) a payload disposed within the payload container, wherein the payload is selected from a group consisting of a solid and a liquid;

a plurality of conduits fluidly connecting (1) an upper storage reservoir to a drop-down system (2) the drop-down system to a power generation system and (3) the power generation system to a lower storage reservoir;

wherein:

the lower storage reservoir is disposed at a first elevation;

the upper storage reservoir is disposed at a second elevation that is greater than the first elevation;

the power generation system comprising a generator and a turbine that rotates upon impact by the plurality of balls to generate electricity, the power generation system being proximate the first elevation.

2 . The facility as recited in claim 1 , wherein the drop-down system comprises at least one inclined conduit.

3 . The facility as recited in claim 1 , wherein each ball in the plurality of balls has a diameter between 0.1 mm and 1.5 m.

4 . The facility as recited in claim 1 , wherein the outer layer comprises a polymer.

5 . The facility as recited in claim 1 , wherein the at least two inner layers comprise elastomers.

6 . The facility as recited in claim 1 , wherein the dividers comprise a composite material.

7 . The facility as recited in claim 1 , wherein the dividers comprise a metal.

8 . The facility as recited in claim 1 , wherein the endosome layer comprises a rubber.

9 . The facility as recited in claim 1 , wherein the payload comprises water.

10 . The facility as recited in claim 1 , wherein the payload comprises lunar regolith.

11 . The facility as recited in claim 1 , further comprising a plurality of secondary balls with a diameter between 0.03 inches and 0.5 inches mixed with the plurality of balls.

12 . The facility as recited in claim 1 , wherein the upper storage reservoir is spaced from the power generation system by an elevation of between 100 feet and 1,000 feet.

13 . The facility as recited in claim 1 , wherein the upper storage reservoir is spaced from the power generation system by an elevation of between 500 feet and 1,000 feet.

14 . The facility as recited in claim 1 , wherein the drop-down system further comprises at least one runway section with rollers embedded in an exposed surface of the runway section, the rollers comprising hub motor-generators that generate electricity upon being rotated by contact with the plurality of balls.

15 . The facility as recited in claim 14 , wherein the drop-down system further comprises at least one wheeled cart wherein the at least one wheel comprises hub motor-generators that generate electricity upon being rotated.

16 . The facility as recited in claim 1 , wherein the drop-down system further comprises at least one wheeled cart wherein the at least one wheel comprises hub motor-generators that generate electricity upon being rotated.

17 . The facility as recited in claim 1 , further comprising an uplift system configured to uplift the plurality of balls from the lower storage reservoir to the upper storage reservoir.

18 . The facility as recited in claim 1 , further comprising a first energy storage system configured to store electricity generated by the power generation system, the first energy storage system being disposed proximate the turbine.

19 . The facility as recited in claim 18 , further comprising a second first energy storage system configured to store electricity generated by the power generation system, the second energy storage system being disposed proximate the upper storage reservoir.
