Breakthrough fresh look on multipurpose inclusion of oceans in economics

Breakthrough fresh look on multipurpose inclusion of oceans in economics Initiator: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com, Israel, Linkedin Abstract (1) Breakthrough cheap artificial mobile islands for holydays, living, industry and terminal applications (2) Seafood farming very cheaply in open oceans [1], [2] (3) Sailboats for wind energy harvesting and transforming it in electricity, being cheaper 1 cent/kWh for further artificial fuels production from air and water see Appendix 1 . (4) Other ocean energies’ and minerals’ harvesting in open oceans (e.g. energy of waves, lithium etc. ) (5) Novel ships of big payload for breakthrough quick transportation for civil and military applications. See Appendix 2, [3] Artificial island is assembled in open oceans from big construction units built mainly of standardized elements, e.g. of thin walls hollow plastic cubes 1.0-2.0 meter high, near a shore and then towed. Such island equipped by movers to control them at desired place or for removing. Appendix 1 Fresh look on wind power generation-Upgraded, 25/02/2019 First version and publication of that breakthrough technology goes back to July, 2017 and was titled as “Fresh look on wind power generation”. That was really a fresh & new look now upgraded into a system, can produce by 0.25 US cent/kWh (because a lion share of the cost is gearless permanent magnet electric generator of USD 80.0/kW) The key idea originally was to transform a route energy of a sail boat into rotation of a generator equipped by a hydraulic turbine with effectiveness near 100%. So the power generation unit is a small pilotless floating structure (SPFS) with a simplest flat sail and relatively small hydraulic turbine is fixed underwater to the SPFS moved by the sail. The said SPFS go there and back. They harvest the wind energy and transform it into electricity. Certainly, we can ask me a way to store and to transport such electricity from the thing floating in the open ocean? We can transform such electricity at first in hydrogen-gas, and then in carbon based fuels or other chemicals to further treating them Some examples of tremendous consequences of my invention in economics and human life: (1) Such cheap and limitless and easy accessible electricity will turn a human life, production and transportation to electricity usage as practically only energy resource and transform design of things and tools for energy effective feeding by electricity. (2) In such case, there would be enough about 40.0 trillion kWh electricity annually in a middle-term perspective to feed all needs of mankind. It can be provided by 4.0 milliards kW power can be provided by 160.0 million simplest SPFS-s of 25 kW each, much simpler and in much less quantity than cars now used, and by total CAPEX of about USD 250 milliards annually during 5 years. Really, it is practically negligible expense in comparison with world GDP. We can imagine a way to solve the all world energy supply problem practically free? Here I did it, and did by green way. I can think that in our turbulent world there are much more reliably to prefer electricity generation in far open ocean than in a nearest sea, even if the electricity would be twice more expensive. Appendix 2 While conventional surface ships’ and submarines’ power consume is proportional to cube of their speed V m/s (1) W ~ V^3 = k * V^3 * B (beam) * H (draft) (kW), my concept’s power is proportional to the speed (2) W ~ V = V * H^2 * B (kW) In my case a ship nose is tilted back from its lowest point to highest one, and the ship is submerged, while its roof is near to the sea level. The ship’s nose as a wedge pushes the front water upward to the air, because the water can be considered as incompressible and continuous medium in our case, so (3) W = Q (m3/s) * H (meters of water column) (kW) (4) Q = B (beam)* H (draft)* l (nose length) / (l / V) =B * H * V Combining (3) and (4), it gives (2) Additional loses of that ship can and must be relatively negligible by using a pressed air cocoon around the sides and the bottom. It is not sophisticated, but routine designer work, had been made by me too. q (kWh / ton-km) = W (kW) / (G (displacement, m^3) * V (km/h)) can be considered as a OPEX. So (5) q = H / (3.6 * L (m)), i.e. depended on H-to-L ratio only and q = about 0.015 or less, and not depended on a ship speed !!! (Here, L – is an effective length of a ship). So q = 0.012 kWh/ ton-km approximately, or 1.5 USA cents/10 ton-km or even much less.
