Abstract

The exemplary embodiments herein provide an airborne power generation assembly comprising an airborne power generation unit, a submersible platform, an electrified tether winch attached to the submersible platform, an electrified tether connecting between the electrified tether winch and the airborne power generation unit, and a power output exiting from the submersible platform. Embodiments include an underwater docking station with a docking station tether connecting the submersible platform to the underwater docking station. The submersible platform or the underwater docking station may be anchored to the sea bed. Other embodiments include winches for the sea bed anchor tethers and docking station tether.

Claims (60)

1. An airborne power generation assembly comprising:

an airborne power generation unit;

a submersible platform;

an electrified tether winch attached to the submersible platform;

an electrified tether connecting between the electrified tether winch and the airborne power generation unit;

an underwater docking station positioned beneath the submersible platform;

at least one sea bed tether connecting the underwater docking station to the sea bed;

a docking station tether connecting the floating platform to the underwater docking station; and

a power output exiting from the submersible platform.

2. The airborne power generation assembly of claim 1 further comprising:

a landing perch extending above the submersible platform.

3. The airborne power generation assembly of claim 2 wherein:

the landing perch is generally U-shaped.

4. The airborne power generation assembly of claim 2 wherein

the landing perch contains a substantially horizontal portion for accepting the airborne power generation unit.

5. The airborne power generation assembly of claim 1 further comprising:

a sea bed tether winch attached to the submersible platform; and

a sea bed tether adapted at a first end for attachment to the sea bed and adapted at a second end for attachment to the sea bed tether winch.

6. The airborne power generation assembly of claim 1 further comprising:

a first electronic controller positioned on the submersible platform;

a second electronic controller positioned on the airborne power generation unit; and

wherein the first and second controller communicate electronically to control the electrified tether winch.

7. The airborne power generation assembly of claim 1 further comprising:

a counterweight suspended from the underwater docking station.

8. The airborne power generation assembly of claim 1 further comprising:

a submersible platform winch attached to the docking station tether.

9. The airborne power generation assembly of claim 1 further comprising:

a ballast pump attached to the submersible platform.

10. The airborne power generation assembly of claim 1 further comprising:

a female portion on the underwater docking station which accepts a male portion on the submersible platform.

11. The airborne power generation assembly of claim 8 wherein

the submersible platform winch is controlled by electrical signals from the airborne power generation unit.

12. An airborne power generation assembly comprising:

an airborne power generation unit;

a submersible platform;

an electrified tether winch attached to the submersible platform;

an electrified tether connecting between the electrified tether winch and the airborne power generation unit;

at least one sea bed tether connecting the submersible platform to the sea bed;

an underwater docking station positioned beneath the submersible platform;

a landing perch extending above the submersible platform.

13. The airborne power generation assembly of claim 12 further comprising:

a sea bed tether winch positioned on the submersible platform and connected to each sea bed tether.

14. The airborne power generation assembly of claim 12 further comprising:

an aperture in the landing perch for allowing the electrified tether to pass through the landing perch.

15. The airborne power generation assembly of claim 12 further comprising:

a shock absorbing mechanism positioned on the submersible platform and placed beneath the landing perch.

16. An airborne power generation assembly comprising:

an airborne power generation unit;

a submersible platform;

an electrified tether winch attached to the submersible platform;

an electrified tether connecting between the electrified tether winch and the airborne power generation unit;

an underwater docking station positioned beneath the submersible platform;

at least one sea bed tether connecting the underwater docking station to the sea bed; and

a docking station tether connecting the floating platform to the underwater docking station.

17. The airborne power generation assembly of claim 16 further comprising:

an upper portion on the underwater docking station which accepts a lower portion on the submersible platform.

18. The airborne power generation assembly of claim 17 further comprising:

a perch positioned above the submersible platform.

19. The airborne power generation assembly of claim 16 further comprising:

a submersible platform winch attached to the docking station tether which is controlled by electrical signals from the airborne power generation unit.
