FIELD OF THE INVENTIONS
Present invention provides some means in humanity's battles; war; our campaign for survival against Global Climate Change; Global Climate Collapse (GCC). Inventors may provide humanity with mitigating solutions such as: new tools; better equipment and systems. Enabling a transformation of our energy systems. From our present dirty fossil fuels based systems to non-polluting clean technologies. Mankind had 8 years to avoid the catastrophic effects of GCC. However, whether we can overcome this “greatest challenge facing humanity.” Whether our civilization can collectively survive beyond this critical test/or become extinct, too, maybe much more subjective. Much more dependent upon factors such as: political will-power; speed of deploying mitigating solutions; people's attitudes; conscious personal choices, decisions; climate leader-ship; climate activism, climate denialism; climate “murders”, climate justice; etc. than mere physical devices. Dependent upon what the Earth's topmost, its cleverest and most intelligent inhabitant1—humanity—does! We humans, are the cause of this PROBLEM. We are also the SOLUTION! To Quote: “What happens next, is up to every one of us”, says Sir David Attenborough in “Extinction: The Facts.” On BBC One, UK; 13 Sep. 2020. “It shows,” says Sir David, “what we can achieve when we put our minds to it. I may not be here to see it,” he concludes, “but if we make the right decisions at this critical moment, we can safeguard our planet's ecosystems, its extraordinary biodiversity and all its inhabitants.” To Quote: “The world is waking up and change is coming whether you like it or not.”—Greta Thunberg.
Present invention discloses the utility purpose of deploying drones and adapting drone and robotic technologies for harnessing high altitude wind energy and deep sea ocean energy to generate renewable energy; displacing use of fossil fuels; mitigating the deadly effects of catastrophic global climate change. Ultimate Goal: safeguard and preserve our one and only life-support-system—Earth's Biosphere; in a habitable condition for all humans, animal and plant species to continue living! That the air we breathe, the water we drink remains clean and healthy; not poisoned by the toxic wastes we generate. Deploying robotic-drones to serve humanity. To generate clean energy; to preserve clean air and water; and a healthy planet Earth for future generations! That humans doesn't follow the dinosaurs—into extinction! Yeah, drones and robots! Drone-bots to the rescue of humanity! Drone-bots, new innovations, materials, systems and enabling means of the Fourth Industrial Revolution (4IR); controlled by means of computerized artificial intelligence (AI) and machine learning may be used to save mankind from this self-inflicted ecological suicide! And in return generation of Ocean Renewable Energies to power the 4IR. Keeping Mother Earth live-able had a direct personal impact on ourselves, our families and unborn babies.
Decarbonization of the global commercial shipping had always been one of the most intractable issues. Since the 1960s; the IMO had initiated for environmental protection from the harmful effects of fuel emissions from shipping traffic. In particular, sulphur oxides, nitrogen oxides, etc. Reprocessing of used cooking oil, fat and grease for use as bunker fuel; sustainable aviation fuel may help in controlling toxic emission. Sustainable self-generated renewable energies on board commercial shipping; ocean liners; coastal vessels for direct use in propulsion may enable the shipping industry to accelerate decarbonization. Panel 920 mounted with multiple wind or tidal-turbine-generators 921 may be used on board for conversion of renewable energies. Renewable electricity generated onboard is directly routed and used for driving the electric engine; propeller for propulsion of vessel 901. Grid energy storage systems comprising: batteries and hydrogen storage sub-systems may be installed for use. When the sun is not shining; the wind is not blowing; or the tide is deficient. This stored reserve of energies may be reconverted back; and used for propelling the vessel. Other energy extraction systems of present invention may comprise: variant specialty tidal drone apparatus 840d; 840e; 850; for the extraction and conversion of tidal energies: partially-afloat-partially submerged; totally submerged underwater; or located at the sea-bed. Wind energy extraction systems may comprise: wind-sail-turbine-generators 880.
BACKGROUND OF THE INVENTIONS
To Quote, Reuters: “About 90% of world trade is transported by sea. Shipping's share of the global CO2 emission amounts to 1056 million tonnes (2.89%) in 2018. The IMO aims to reduce the industry's overall GHG emission by 50% from 2008 levels by 2050.”—Reuters. Dated: 5 Aug. 2020. Decarbonizing the global shipping industry; and the aviation industry had always been the most difficult. A possible solution lies in the conversion of ships; and airplanes to use green hydrogen for propulsion. Historically, wind energies powered sails had been an important means of propulsion for sea-faring vessels. Wind assisted solution—sails; reduces a vessel's dependence on fossil fuels. Where these vessels plies; wind and tidal energies are in plentiful and constant supply. If conversion devices and apparatus are installed; used on board these ocean going vessels for direct generation of renewable energies; this self-created energy may directly be used to drive; to power; to propel the vessels. Any excess energy produced may be stored in grid storage systems for later use. Such that even when the ships may be at berth; during port calls. That is—stationary; not moving. The solar, wind and tidal energies conversion devices; apparatus it carries on board continues working. Generating sustainable, renewable energies for utilities; and for storage. For use when the vessels are sailing. Heading toward the next port.
SUMMARY
Present invention discloses systems, methods and techniques of adapting and transforming wind and tidal energies into renewable energies. The wind-sails 877 enables engagement and enhances conversion of wind and tidal energies into useful electrical energy. The use of like: semi-solid; or solid state shrouds, hoods, ducts; casings affixed externally to the turbine-generation units improves conversion efficiency by directing and channelling a stream of high velocity fluid flow into the turbine generators 500vz; 500az; 921. Besides the use of specialty panels 920 embedded with a multitude of turbine-generators 921 onboard vessel 901. Other apparatus and devices may be used for engaging, extracting and converting wind, tidal; wave energies. Including components and apparatus disclosed in the parent patents, such as: 471z; 477z; 100z; 40z; 200z; 222z; 400z; 500az; 500vz; 800az; 800bz; 800cz; 800dz; 800ez; 800fz; 800gz; 800iz; 800jz. Airborne high altitude wind energy generators 100z; 400; 800z. And deep sea diving tidal energy generators 200z; 222z. Optionally, apparatus 100z; 200z; 222z; 800iz may be used for providing traction propulsion for the vessels. Solar energy may also be extracted by means of solar tiles 895; solar paint 875; etc. The Circular Energy Conversion Pathway may be outlined as such: Kinetic energy (wind; tidal)→mechanical energy (turbines; bags)→electrical energy (generator)→mechanical energy (ship's electric motor; propeller)→kinetic energy (vessel's mobility).

The IMO aims to reduce the industry's overall GHG emission by 50% from 2008 levels by 2050.”—Reuters 5 Aug. 2020. Decarbonizing the global shipping industry; and the aviation industry had always been the most difficult. A possible solution lies in the conversion of ships; and airplanes to use green hydrogen (stored in ammonia; formic acid; methanol; toluene; etc.) manufactured by means of renewable energies for propulsion. Historically, wind energies powered sails had been an important means of propulsion for sea-faring vessels. But when the wind doesn't blow. Or. When the wind isn't blowing in the correct direction that we desire—towards a harbor; a port; a destination . . . . Your Goal! The captain would be faced with a dilemma. Except to use an internal combustion engine (ICE) for propulsion. But heat engines pollutes. And our climate is collapsing due to such pollution! This enigma might be resolved by features of present innovation. Regardless of the wind direction. Even if the wind is blowing directly against the ship's bow. Blowing from the very direction vessel 901 is heading towards. However, like all renewable energies solutions, upfront capital investment is required in return for long-term-cost-savings in operating expenditure. The ultimate goal of this innovation is to achieve true “net-zero-energy”; “net-zero-emission” shipping; wherein said vessel 901 is configured to produce adequate power sustainably from the environs to meet its own propulsion and utility needs. That it consumes only as much power as it produces sustainably. Without any external off-sets; for example: like planting trees to create carbon sinks. Bringing about: evolutionary; transformational changes; and energy independence; to the blue ocean merchant fleet.

Achieving self-sufficiency in conversion of renewable energies into propulsion energies; mobility; combined with storage capabilities would be an empowerment of the global “net-zero-emission” shipping industry. In achieving total decarbonization. And a clean energy revolution. Freedom from energy poverty. Freedom from the shackles of dirty fossil fuels! An energy independence! By means of self-generating systems (of energy production); electrified propulsion; and grid energy storage systems. Negating the present need for said vessel 901 to take on large quantities of polluting bunkers: fuel oil; diesel; natural gas. Which is a necessity at present. For emergency back-up purpose vessel 901 may still stock some bunker fuel; maybe (10%-30%) in comparison with present day use of 100% fossil fuels. Only as a last resort may diesel (fossil fuel) be used in an emergency in internal-combustion-engine driven generator 911; natural gas with a gas turbine generator unit 915′ to supply electricity for propulsion.
Vessel 901 may be configured; adequately provisioned with renewable energies extraction-conversion means 920 for self-sufficiency in the generation of sustainable energies.

Vessel 901 may also be replenished with new classes of decarbonized “bunkers” comprising: green liquid ammonia; formic acid; toluene; compressed green hydrogen; liquified green hydrogen; etc. The green liquid ammonia is saturated with green hydrogen. Likewise, other chemical energy carriers may also be used to supply power for propulsion such as: formic acid; toluene; etc. and maybe replenished at the ports of call. Note: Green hydrogen may also be produced by means of a variety of different sustainable systems such as: catalytic-induced chemical reactions; photo-catalytic-induced chemical reactions; bio-catalytic-induced reactions using enzymes; etc. Green hydrogen derived from such methods and systems may be bottled up and stored for use.
When vessel 901 is at berth in port. While some units of panels 920 may be removed and kept in storage due to space constraint. Other units may still be kept in operation on unused space of deck 736z. Other components of system 920 comprising airborne and seaborne (tidal; wave) energies extraction units: 76z; 100z; 200z; 222z; 800bz; 800z; 874; etc. would still be kept working.

Conversion of excess energies for filling up: hydrogen bottles 907; tank 549z; conversion of hydrogen produced into ammonia stored in tank 704z. When the storage systems are fully packed, excess energy may be exported by cable to other vessels in proximity. Or. Exported to the port authority. This might be an evolutionary change. A metamorphosis. A transformation. From a dirty-fossil-fuels guzzler; seafaring vessel 901 had morphed into a self-sufficient “net-zero-emission” entity in clean energies production. And maybe, occasionally, to being a net exporter of clean energies. Such is the beauty of innovation!

While push-button operations of automated systems simplified operational use. Optionally, turbine generators 921 may be covered up with flat pieces of panel materials 924. This may be feasible when energy production exceeds propulsion and storage needs. For example: in gale force wind. With the vessel moving full speed ahead; and the grid storage systems 910a; 910b fully charged. So instead of generating excess energies which can't be used or stored. Swapping of generation apparatus 920e; 920f; with traction apparatus 920e′; 920f′. Conversion of panels 920 from a means of energy generation into a means of traction may prove to be a logical choice.

Supporting structures and apparatus may comprise: pneumatic; hydraulic systems and crane booms 619; embedded into the deck. They may be extended for use; retracted and stored when required. Wind energies may be harnessed at all times. Whereas tidal energy may need to be harnessed selectively; dependent upon tidal flow versus the direction of ship movement; or at berth. Conversion of existing vessels may expedite evolution of more green vessels. Components of system 900 may also be selectively adapted to benefit coastal transport such as: boats; ferries; skips; jiffs; fishing boats; etc. Likewise instead of ships; specially configured tracked; wheeled land vehicles equipped with preferred wind energy extraction-conversion systems; and energy storage system (disclosed above); and electrified propulsion system.

FIG. 3K illustrates use of sustainably generated fuel comprising: compressed hydrogen liquified hydrogen; derived from electrolysis of water using renewable energies. Including conversion of green hydrogen into ammonia. Which may then be liquified, containerized for distribution and use. Presently, due to the inherently high risks and hazards involved in handling of these chemicals. Extreme safety precautions and limitations are placed on their utility purposes. Often by force of local safety regulations and laws. This is good for the safety of the public. But at the same time, such restrictions goes contrary to widespread public adoption and utilization of new products and systems. This maybe mitigated by means of extremely robust design standard; configurations in the fabrication of containerized eco-systems; safety and health precautions; creating a large base of trained personnel; handling instructions; public awareness, education and promotion; etc. Just like the use of hydrocarbon based fuels and products by the public, such as: diesel; gasoline; aviation fuels; LPG cylinders (cooking, heating); domestic and industrial piped natural gas networks; etc.
The fossil fuels we used in our daily lives are not without risks and hazards. But with adequate safety precautions, trained personnel; hazard awareness; robust system designs, etc. they can be handled and used safely. Green hydrogen or green ammonia may also be packed; stored; transported; and distributed in containerized form to customers; consumers; for use. Much alike the use of LPG containers. Customized containers specially configured for hydrogen gas may/would be used. Likewise specialized adaptors; fittings; hoses; etc. maybe configured for use with hydrogen gas. Including procedures; instructions; hazard awareness; hands on practical training; in handling; storage; transport; utility. Likewise a similar set up may be required for liquified ammonia; albeit a with a less stringent criteria for ammonia due to different inherent risks and hazards involved. Containerized storage; transport and distribution would enable speedy adoption of these new energy carriers: hydrogen and ammonia. A global infrastructure exists for ammonia handling, transportation and distribution. But non-existent for hydrogen at present. A new infrastructure may be developed for hydrogen in future. Optionally, hydrogen may ride on the existing ammonia infrastructure by means of conversion into ammonia until such time. Convenience; availability; pricing; ease of utilization; spare containers for back-up; plug and use concept; extended range; continuous use; etc. would be the main determinants in customer acceptance. In comparison with the present limitations of making compressed hydrogen or liquid hydrogen being confined to a few specialized kiosks or depots.
FIG. 4A illustrates an encapsulating vacuum system 940; configured to protect; and to keep the generation unit 777z of a nacelle; in a safe condition. Purpose of system 940 being to avoid; to eliminate: the occurrence of electrical sparking; flash-arcing in the highly energized electrical power generation equipment; components; and apparatus. Vacuum system 940 may also be used together with like: high energy; high voltage; electrical switch-gears; transmission equipment; etc. Occurrence of such electrical sparks; flash-arcs may cause: electrical explosions; fires; severe damage to equipment and properties; system down-time. And severe personal injuries; deaths.
A generator unit 777vz including planetary gear 830; maybe kept sealed inside an enclosed housing structure 939. Surrounded by a specially created vacuum cavity 940′; or a semi-vacuum cavity 940′; to avoid formation of electrical sparks; flash-arcs. The external housing structure 939 being configured to withstand the atmosphere pressure on the external surface; versus a vacuum condition on the internal surface (cavity 940′). Such that the enclosed generation unit 777vz within shall exist; and be maintained in a permanent state of vacuum; or a state of partial-vacuum when it is in operation. Such a vacuum condition minimizes; eliminates the high risks; and hazards related to electrical sparking; flash-arcing; induced fires and explosions. Thus safe-guarding the safety; integrity; reliability of high-tension generation units. Similar concepts for creating such a vacuum enclosure 940 may be applied to and used for other electrical switch-gear equipment; and related electrical facilities. Chemical based spark; flash-arcing; suppressants exists. And may be used to ensure safety of equipment and personnel. However, such chemicals possess inherent disadvantages. When leaked, they are hazardous to the environment; and exacts a very high environmental cost. Whereas system 940 provides an alternative, non-hazardous solution; which might be more costly to implement. But which in itself carries minimal; in fact, zero inherent risk; zero hazard. The paramount selection criteria for such safety equipment or materials being to: (a) cause NO harm. (b) bring required benefits. Related auxiliary equipment of system 940 may comprise of: multi-layered seals 935; packings 935′; sealing-rings 935; installed on shaft 936; sealant tank 937; vacuum tank 938; vacuum-compressor-unit 941′; back-up vacuum unit 941″; level sensor 942; pressure sensor 943; pressure transmitter 943′; and a computerized safety-integrity-management-system (SIMS) 944. System 944 may be used for: remote monitoring; alarms; alerting human operators; and an autonomous safety shut down system for faulty equipment. The housing structure 939 may be supported by solid struts 939′. Vacuum system 940 may also be used with other generation units such as: 585z; 590z; 777z; etc.
A brief description; and a standard operating philosophy of system 940 maybe outlined here. When a leak occurs in the sealing system comprising a plurality of seals 935; packings 935′; or sealing-rings 935; etc. installed on the axle or shaft 936; of the generator 777z. Sealing fluid present in the pressurized sealant tank 937; automatically goes into the leaking seals 935; packings 935′; replenishing lost fluid to stop the leak. As a result the level in the sealant tank 937 drops. This change in level is transmitted to the SIMS computer 944; by means of electronic signals. Vacuum cavity 940′ is linked to vacuum tank 938 by means of hard piping 945. Air leakage from the external environment into the vacuum cavity 940′ causes a loss of vacuum; and a corresponding rise (an increase) in the pressure of the vacuum tank 938. This change in tank 938 vacuum is fed-back and transmitted by pressure transmitter 943′ to the SIMS computer 944. When the vacuum pressure of tank 938 reaches a pre-set parameter; a pre-determined set point; due to this ingress of air. By means of electronic signals; the SIMS computer 944 activates the vacuum-compressor-unit 941′ to run. To reduce the tank 938 pressure; to re-establish the required vacuum parameter; setting. Preference would be given to run the electric driven vacuuming unit 941′ powered by means of batteries or renewable energies. To reduce the required vacuum condition in vacuum tank 938; to its pre-determined set-point. If for whatever reason unit 941′ fails to run. Then the back-up vacuum unit 941″ powered by means of bio-diesel or blended-diesel; would be activated by the SIMS computer 944 to re-establish the vacuum pressure in tank 938. SIMS computer 944 then stop unit 941′; 941″.
Such a dedicated vacuuming system 940 may be configured; integrated into the generation unit 777vz of the nacelle from the design stage. Such that the external housing structure 939 and the generator body 777vz may be integrated into a single unit. Only the multiple seals 935; and packings 935′; need to be directly integrated with the shaft 936. This is the one and only interface between the internal vacuum versus the external atmosphere. Sealant tank 937; and SIMS computer 944 may be configured next to the seals 935. The other components comprising: vacuum tank 938; vacuum-compression unit 941′; 941″; maybe configured at besides generator unit 777vz.
Optionally, in a renewable energy farm setting; where multiple generators: 777z; 777vz; standard generators 473z; of wind and tidal turbines 471z; exists. All of these generation units may configurably; be integrated and combined to be served by a single vacuuming unit 940. This centralized vacuuming system 940 may be configured with a much larger capacity; including up-sized: vacuum tank 938; vacuum-compressor units 941′; 941″; and additional components. When a leak is detected in the system following a drop in the sealing fluid level 942 in individual tank 937. For example: generator unit 1 (identified by number: G1). This change in level is transmitted to SIMS computer 944; and maybe used to indicate; identify; pin-point the particular; specific faulty seal; or unit monitored under system 940. All units may be identified by means of designated numbers such as: G1; G2; G3; G4; G5; etc. And the automated valves identified as: V1; V2; V3; V4; V5; etc. maybe remotely operated (closed; opened) by computer 944 sequentially. This may be used to determine leakage from the specific seals of the plurality of generator units from: G1 to G5; etc. In case of a severe leak in G1; SIMS computer 944 would shut the automated valve V1; and also trigger the shut-down of the whole generation unit 777vz (G1); including the front-end energy extraction component by means of declutching and feathering the conversion systems. For example: wind turbine 471z; or tidal turbine 471z.
FIG. 4B and FIG. 4C illustrates optional configurations of FIG. 3A and FIG. 3B. In which an existing fossil-fuels-burning vessel 901; maybe speedily transformed into a zero-emission-vessel ZEV-901. Without any retrofit or major modifications. Only minor adaptations may be made to hook-up vessel 901 with twin units of specially configured, dedicated, zero-emission-vessels ZEV-tug boats 946p; 946s; located port and star board. By means of extended bars 947; and vertical traction masts 948; forming a trimaran. Such that the specialized; customized ZEV-tug boats 946p; 946s; may impart its renewable energies derived mobility-propulsion means (920; 930; 477z; etc.) to the main vessel 901; with its carbon guzzling (polluting) engines shut-off. ZEV-tug boats 946p; 946s; may be located at the fore; front of vessel 901 pulling it by means of a tow line. Or, it may be located at the aft; stern of vessel 901; pushing it from behind. Avoiding the need for 901 to run its polluting engines; which may be kept in reserve. At berth in port the ZEV-tug boats 946p; 946s; maybe disconnected from vessel 901; for ease of cargo handling. Then reconnected up again outside of the anchorage areas. Extension bars 947; traction masts 948; maybe configured to be extendable; retractable; much alike hydraulic booms 619z. In practice, extension bars 947 maybe brought in proximity to traction masts 948. And connected together mechanically by means of clamps; and/or bolts and nuts; etc.
FIG. 4B shows the rear view of a vessel 901 flanked port and starboard by twin ZEV-tug vessels 946p; 946s; transmitting their propulsive power by means of a plurality of extended traction bars 947; and vertical traction masts 948. ZEV-tug vessels 946p; 946s; maybe configured with a multitude of airborne wind turbine generators 800z; 800bz; 800az; and seaborne tidal generators 800z; etc. for generating electricity to power the prime movers 905; 912; 906. Including components of: energy generation system 920; energy storage systems 910a; 910b; energy conversion system: 902; 903; 904′; 509z; 907; 549z; 918; 704z; 908; 909; and propulsion systems: 904″; 905; 583z; 586z; 912; 906. Optionally FIG. 4C shows a vessel 901 outfitted; hooked up with twin detachable outriggers 949p; 949s; connected by means of a plurality of extended bars 947; mast 948.

Thus extending its energy mining acreage; area of coverage; increasing its volume of renewable energies extraction. High up into the atmosphere by means of flying drones 800z cum windbags 30z. Deep into the ocean by means of diving tidal energy extraction apparatus 800z cum tidal-bags 40z. Instantaneously transforming vessel 901 from a dirty, polluting carbon-emitting vessel into a clean, zero-emission vessel ZEV-901.
The aviation industry accounts for around 2-3% (915 million tons); out of a total of 43 billion tons of all human-induced CO2 emission in 2019. Including global emission of: 9% SOx; 18-30% NOx. The aviation industry had pledged to halve net CO2 emission by 2050. Around 80% of aviation CO2 emissions are emitted from long range flights of over 1,500 km. Decarbonization of the aviation industry may be enabled by means of unique ecosystems specifically developed to cater to the needs of this global sustainability requirement. To be free from being enslaved; freed from the shackles of dirty fossil fuels. Humanity needs to resolve issues related to supply of fuel; storage; logistics; etc. such as: (1) Development of renewable hydrogen industry in ensuring a reliable supply of cheap green H2. (2a) Hydrogen Fuel Cell (HFC); Solid Oxide Fuel Cell (SOFC); Hybrid-SOFC; electrified propulsion systems; (2b) Gas turbine engine propulsion systems using a green hydrogen-methane blend, initially as propellent for the hybrid gas turbine engines; gradually moving to 100% green H2. (3) Storage of fuel on aircraft. Storage of compressed hydrogen may only suffice for short range flights. While storage of liquid hydrogen for the entire long distance flight may entail voluminous cryogenic tanks (−253 deg. C). Use of liquid ammonia for inflight conversion into hydrogen for propulsion may offer a safer option; less technical-engineering challenges; enabling 1.5 times more hydrogen storage capacity; in comparison with using liquified hydrogen. (3a) Hydrogen to power hydrogen fuel cell—electrified propulsion system. (3b) Hydrogen to power specifically configured gas turbine engines with 100% hydrogen gas. Optionally refueling of green or synthetic aviation fuel (kerosine) may also be done such as: Jet A-1; JP-8. For safety purposes; and to reduce weight and space, carriage of cryogenic (−253 degrees Celsius) liquid hydrogen abroad may, preferably be limited in quantity. This limitation may be resolved by refueling stops. And where this stop-over is not possible; or infeasible: for example, in the middle of the ocean; airborne refueling systems may be used to resolve such deficiencies. (4) A viable airborne refueling and top-up system enabled by means of: (4a) A standard airborne refueling system similar to a flying tanker used by the national Airforce of numerous countries to resupply military aircrafts while in active flight. Requiring advanced technological guidance; precision aerial techniques; skills and training of the air crew. (4b) An airborne drone based ecosystem 950: centered around an airborne tanker 951; which may be configured to carry multiple units of: drone 952 mounted cylinder 953 filled with aviation fuel. Said ecosystem 950 maybe specifically configured for delivering green liquid hydrogen 954; green liquid ammonia 954; green aviation fuel (JP-8; Jet A-1) 954; to refuel aircrafts 955 requiring top-up. Airborne tanker 951 may be configured with a cryogenic tank cum associated refrigeration system for handling liquid hydrogen; which maybe transferred into drone 952 mounted cylinder 953 shortly before its release from airborne tanker 951; then flying to deliver its cargo 954 to refueling aircraft 955.
Such an eco-system 950; may be configured for refueling long range flights of over 1,500 km. As this sector is responsible for around 80% of aviation CO2 emissions in 2019 (915 million tons). Carrying a full load of liquid aviation fuel such as green JP-8; Jet A-1; maybe a normal practice at present.
However, for aircrafts to fly fully laden with voluminous cryogenic tanks (−253 deg. C) of liquified hydrogen for the entire journey. Imposes an undue safety burden that might well be dispensed with; by means of mid-air refueling ecosystem 950. As an aircraft carrying a partial amount (for example: half-load) of liquified hydrogen fuel, maybe viewed more favorably in terms of safety. Particularly in mitigating the high risks; hazards; and safety concerns associated with liquified hydrogen under cryogenic conditions. Such an optional arrangement thus reduces the weight; and storage space of liquid H2 fuel carried abroad. Which might be repurposed for other uses. Likewise, sustainably manufactured liquid ammonia; JP-8; Jet A-1; may also be delivered for top-up by means of eco-system 950.
FIG. 5A illustrates such a system 950; wherein, said airborne tanker 951; carries a plurality of specially configured UAVs; drones 952 integrated, mounted with fuel cylinders 953; canisters 953; fuel tubes 953; maybe used to safely transport and deliver; a cargo of green, zero-emission aviation fuels 954. The fuel cylinders 953 may contain green: compressed hydrogen; liquified hydrogen; liquified ammonia; liquified bio-methane; liquified synthetic-methane; etc. Other fuel-cargo supplied may comprise green synthetic kerosine such as: JP-8; Jet A-1; etc. The compatible fuel supplied by ecosystem 950 to the refueling aircraft 955 may be used directly with the ICE engine; gas turbine engine; or, undergo conversion into electricity by means of: PEM-Catalytic-Filter 908 unit; Hydrogen-Fuel-Cell stacks 909 unit; SOFC 909 unit; to drive electric power plants 905; etc. Including other means of conversion and propulsion that future R&D may uncover.

FIG. 8A illustrates the perspective view of a floating wind turbine 990a supported and sitting on top of a plurality of floating and submerged ballast tanks 993′; 993; 994. Floating ballast tank 993′; submerged ballast tank 993; maybe horizontally configured. Submerged ballast tank 994 maybe vertically configured. Vertical tank 994 may comprise of a SPAR structure; or a plurality of tubular structures; affixed to the ocean bottom 537z anchoring system 660z by means of lines 295z. Optional anchoring points may also comprise underwater reliefs such as seamounts 556z; 559z; etc. Horizontally configured ballast tanks 993′; 993; may be hydro-dynamically shaped in the shape of a disc; a semi-disc; or an elliptical-disc structure for supporting the entire mass of the surface turbine structure comprising: pillar 469z; and wind turbine 471z. Wind turbine 471z comprising: turbine blades 472z; nacelle 611z containing counter-rotating generator 777vz; (planetary gears 830z; generator 777z). Floating ballast tank 993′ may be flexibly affixed to pillar 469z; enabling it to rise up; sink down; sliding up and down the lower portion of pillar 469z as commanded.
The bottom-most portion of pillar 469z may comprise of a ball-like structure 995; sitting securely in a round groove 995′; of the submerged lower ballast tank 993. This enables turbine pillar 469z a certain amount of forward or backward tilting movement; to move fore and aft. This helps in absorbing the sudden force created by stormy wind blasts; squalls. The pillar 469z may then be up-righted by means of inbuilt mechanisms such as springs; mechanical jacks; lines 996; etc. Ballast tank 993 may be configured internally with a plurality of segmented sections 997; separated by walls 997′. Sections 997 maybe filled with ballast water 681z; or buoyancy air 683z; controlled by automated ballast sub-system 686z.
Located below horizontal tank 993; a vertically configured submerged ballast tank 994 may be utilized to support the surface turbine structures. It may also serve as a stabilizer; counteracting; counter-balancing the mass (weight) of the surface turbine structure comprising: pillar 469z; turbine blades 472z; nacelle 611z; and the enormous resultant conversion forces of high velocity wind. SPAR structure 994 may be partially filled with ballast water 681z; and compressed buoyancy air 683z. This ballast water 681z; and buoyancy air 683z may operably be adjusted by means of automated ballast sub-system 686z; artificial intelligence (AI) and machine learning algorithms; relative to meteorological reports and ambient conditions. Ballast sub-system 686z or similar automated systems may be used for supporting, adjusting and controlling the buoyancy of floating tank 993′; submerged tanks 993; 994. Including manipulation of drone control surfaces 69z mounted on tanks 993; 994. Enabling apparatus 990a to submerge, sink deeper into the ocean during stormy conditions. With slightly lowered turbine wing tip height. While during fine weather condition with lower wind velocity, buoyancy of apparatus 990a may variably be increased enabling it to attain a higher wing tip height. To harness higher velocity wind at greater altitude. Enabling the utility purpose of keeping floating wind turbine system 990a operationally feasible; while enhancing its efficiency and productivity. Use of counter-rotating generator system 777vz (generator 777z integrated with planetary gears 830z) enables reduction of the power generation system by approximately half (50%) of the total mass of a standard electrical generator. A substantial reduction of 50% generator mass (in nacelle 611z) located on top of pillar 469z helps in reducing structural forces, such as strain and stress forces exerted on pillar 469z.
FIG. 8B illustrates the perspective view of a floating wind turbine configuration apparatus 900b; which is a variant of apparatus 900a illustrated in FIG. 8A. FIG. 8C illustrates the plan view of FIG. 8B; in which an arrangement of supporting bars 998 held ballast containers 999 together. This variant configuration 900b is basically similar to apparatus 900a; except for the floating sea surface 621z components 998; 999. The floating tank 993′ may be replaced by a multitude of horizontal bars 998 and smaller containers 999; surrounding the floating wind turbine 471z; 469z. Containers 999 may be arranged in a vertical or horizontal position; and may be configured with variable ballast and buoyancy responsive to changes in the ambient conditions. Such that faced with impending stormy weather, containers 999 located aft (right hand side of diagram FIG. 8B; FIG. 8C) of the wind turbine 471z may be filled up with more compressed air (water expelled) to increase buoyancy; and the supporting bars 998 may be extended further backwards (longer); enabling it to withstand a heavier load in storms. When the storm passes and ambient conditions normalizes, the buoyancy of container 999; and the length of supporting bar 998; may revert back to their previous operating configurations.
FIG. 8D illustrates the front sectional view of system 740z; a variant marine-hydro-kinetic energy conversion apparatus 740z which is a variant of apparatus 740v (Refer to FIG. 5E; and FIG. 5F of parent U.S. Pat.

Shaft 691z may be enclosed in protective cover 473z. Deck 736z mounted generation systems 777vz (on outrigger 747z′) may be configured of standard materials without water proofing. And thus much cheaper to make; accessible, easier to check, inspect, maintain and repair. That is, if it is compared with the submerged generation unit 777vz of integrated turbine generator unit 471z mounted on outrigger 747z″. Though transmission by means of gear-box 583′; 583″; and extended shaft 691z to generator 777vz may incur some loss of energy; resulting in reduced efficiency and productivity. Each sub-system had its pros and cons. Its a matter of balancing: costs; and practicability versus efficiency; productivity. Submerged components such as turbine blades 472z; gearbox 583z′; shaft 691z; etc. may be lubricated and cooled by the very tidal flow it is harnessing for conversion into renewable electricity.
