Being very productive principle inventor and investigator on a firm basis of my work in wide spectra engineering and economics, I am sure that energy and production have to be and are ready to be green & cheap & abundant & inexhaustible, while all materials and parts and tools for that purpose can be recyclable.  

I can declare that hydrogen economy and either hydrogen or hydrogen rich fuel like ammonia is a dead end paradigm that has been fooling humanity for decades.   

I can declare that the best fuel is, was and will be a carbon based fuels produced from the water and the air by extraction a carbon dioxide of it, and the best way to consume such fuel as for stationary as for mobile applications, it is its high temperature reforming by the water vapor to produce clean hydrogen with carbon dioxide as an exhaust, and following use such hydrogen without any storage immediately by hydrogen-air fuel cell with total system efficiency about 65 % into electricity in comparison with simple burning such fuels, but into heat

Vehicles can be fed on streets and on main roads for suburb and land.

Carbon hydrides would be most powerful and energy effective fuel being relatively safe, while slightly poisoned ethanol is a most safe fuel against terrorist attacks.   

As a novelty, I can offer my invention allows such carbon based fuels production by extremely green & cheap & abundant & inexhaustible way in open oceans (see Appendix 1). It allows on-board electricity by USD 0.0025/kWh, hydrogen by USD 0.20/kg, and carbon dioxide less than USD 20.0/ton

Another novelty is my sea transport allows incredible cheap and quick transportation in general, and such fuels transportation in particular (see Appendix 2). It allows transportation OPEX by USD 0.012 kWh/ton-km, isn’t depended on the ship speed.

Here I intend to show my thesis a little detailed.

Carbon hydrides

(1)  (CH2) + 2 H2O = 3 H2 + CO2 – 254 kJ (heat)

(2) (CH2) + 1.5 O2 (air) = CO2 + H2O + 604 kJ (heat)

254/604 = 0.42, so

(1a) 1.42 (CH2) compensates the heat losses

(3)  3 H2 + 1.5 O2 (air) = fuel cell of 67% efficiency = 3 H2O + 858 kJ * 0.67 = 575 kJ electricity.

So total system efficiency k = 575 / (604 * 1.42) = 67% vs. the carbon hydrates burning, but into heat

Analogous calculation gives the same result for ethanol and for methane

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.
