Practical system for cheap energy for all mankind needs
Practical system for cheap energy for all
mankind needs

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 improved
and upgraded ([3870]- 26.08.2018) into a system, can produce by 0.2 US cent/kWh
and deliver the electricity reliably and safely to any point of the world in
practically unlimited quantity by final cost of 0.4 US cents for any consumption
schedule.
The key idea originally was to
transform a route energy of a sail boat into rotation of a generator equipped
by a special hydraulic turbine with effectiveness near 100%.. Now I offer to
hang the sail in a form of thin mattress filled by hydrogen at height of
200-300 m with much more wind pressure A small pressure of the said hydrogen serves
to support a form of the sail against variable wind speed.
Two ropes are enough to control
the sail position from the boat, can be pilotless.
At any sea or ocean the wind at
the said heights is about 10 m/s, so the wind at 45 grade to the sail of H * B * = 50 m * 20 m = 1000 m2 can produce 300 kW electricity by 0.2 US cents/kWh with the
said generators of USD 80/kW, e.g. permanent magnet direct-drive ones,
do not need the gearbox.
Certainly, we need to transform
on-board the said electricity to something being suitable for transportation
from the moving boats, and it is hydrogen gas produced thermally from desalinated
sea water, then collected and transported to the artificial island for hydrogen
liquefying, if a long distance, and then in thermal insulated vessel by
hydrogen blimp by air, using the said liquid hydrogen as the said blimp fueling.
The liquefying will double a
cost of electricity vs. its sea/ocean origin one, while cost of transportation with
liquid hydrogen fueling is relatively negligible for more than 150 ton cargo and up to
10,000 km transportation and then electricity producing for micro-grids by
hydrogen-air fuel cells from our cheap liquid hydrogen, is suitable for
long-term storage of some months up to a year for the micro-grids.
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) About 40.0 trillions kWh
electricity would be enough in a middle-term perspective to feed all needs of
mankind. It can be provided by 4.0 milliars kW power can provided by 15.0 millions
simple boats of 300 kW each for races with reverse of 0.04 km2 water for each , totally about 100 milliard USD annually for 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.
It would need about of 0.12% of
oceans surface area for world range power plants.
Mediterranean Sea surface (2,5
millions km2), Black sea (550,000) km2, North Sea (570,000 m2), are 3.5 million
km2 totally, and 4.0 % of it as the power farm can cover all energy needs of EU
+ Ukraine + Belarus + Moldova + Georgia by electricity and hydrogen gas without
costly hydrogen liquefying, so by electricity as cheap as 0.2-0.25
Eurocents/kWh.
Nevertheless, 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.
