But, given your post history here where you have authored the content,

Therefore you will be incapable of posting intelligent statements, and

China achieves breakthrough in ocean thermal energy power generation
CGTN

China\'s first set of floating devices that can turn ocean thermal energy into electricity has successfully completed sea trials in recent weeks, marking a significant step forward in the country\'s utilization of renewable energy sources.

Ocean thermal energy conversion is a process that can generate electricity by making use of the temperature differences between the sea surface and deep ocean. China is endowed with plentiful of ocean thermal energy conversion resources.

The floating ocean thermoelectric power generator, developed by domestic researchers led by the Guangzhou Marine Geological Survey, was aboard the marine research vessel Haiyang Dizhi-2, or literally Ocean Geology No. 2, to carry out its first sea test in the South China Sea at a depth of 1,900 meters.

The trial power generation process lasted over four hours, with a maximum power output of 16.4 kilowatts.

The test has proved the feasibility of the country\'s independently developed ocean thermoelectric power generation system both theoretically and practically.

\"We have mastered the core and key technologies including turbine power generation featuring small temperature differences and wide load range, heat preservation of water collected from deep sea, and cold-water pipeline installation,\" said Ning Bo, a senior engineer with Guangzhou Marine Geological Survey under China Geological Survey.

\"We have fully leveraged the high-quality industrial cluster in Guangzhou\'s Nansha District and systematically integrated the resources of multiple competitive enterprises. The device is completely homegrown, with low cost and impressive adaptability,\" Ning said.

\"Although viable OTEC systems are characterized by Carnot efficiencies in the range of 6%–8%, state-of-the-art combustion steam power cycles, which tap much higher temperature energy sources, are theoretically capable of converting more than 60% of the extracted thermal energy into electricity.\"

Horrendously wasteful and inefficient method of energy generation. They could do better with large arrays of potato batteries.

Iceland is a home for Geothermal power and has potential to generate as much energy to power the whole world

My friend lives on the Iceland and he gets warm water for free

What matters in case of mobile, ocean bound OTEC is an ability to move such facility off-shore and there is no limit on thermal energy volume offered..

I build Peltier heat pumps and magneto-inductive flow meters as energy generators.

\"Warm surface water is pumped through an evaporator containing a working fluid.

What makes the working fluid to turn into water vapor, as in the image:

https://www.eia.gov/energyexplained/hydropower/images/oceanthermal.png
You probably need to study the physics of evaporation. Even at room temperature water vapor evaporates from liquid water. What is important is that this vapor has a pressure. The condenser has a lower vapor pressure.

The difference in temperature is what drives the difference in vapor pressure. The pressure difference provides the energy to drive the turbine.

We are used to high temperatures and pressures being used for power generation. That is not required. It does make the energy transfers more efficient.

--
Water can evaporate at room temperature if energy is consumed to generate vaccum.

What is depicted in the image
https://www.eia.gov/energyexplained/hydropower/images/oceanthermal.png

is the working standard in refrigerators

But water is no low temperature evaporation fluid at ambient pressure.

So this is not water acting as a working fluid.
You probably need to study the physics of evaporation.
I stand by my statement that you need to learn more about what is going on. You can\'t understand this process, until you understand that the vapor pressure from the evaporator is higher than the vapor pressure at condenser. Once you understand that, you will grasp that there is energy available to drive the turbine. There\'s no need to create a vacuum of any sort.

If you can\'t get your head around this, then picture the condenser forming a partial vacuum. Whatever. There\'s no magic. The system works as shown. Learn about it.

\"Warm water is drawn from the surface layer into a heat exchanger to vaporize a working fluid with a boiling point of about -30°C.

I\'m sorry that you get so emotionally involved with these simple discussions. Let\'s just try to discuss this and figure out what you\'ve done wrong..

I can\'t explain the discrepancies that you are pointing out, other than to say they probably relate to different systems. The block diagram clearly shows a system using water vapor as the working fluid. That is why it produces fresh water from the condenser. If any other working fluid were being used, there would be no fresh water involved at any step and the working fluid would be returned to the evaporator.

Exactly which system are you quoting text about? The text you quoted is from the page about the Global OTEC Resources facility. The image is from the web page about an experimental OTEC plant on the Kona Coast in Hawaii

So, you posted an image regarding a different system and now are blaming everyone else in the world for it.

Do I have this correct?

You must be mind-sick since you don\'t control you delusional ideas and claims

Wrong

https://www2.dawsoncollege.qc.ca/dbaril/Tools/H2O_Vapor_Pressure/H2O_VapPressureHg.htm

It has vapour pressure of 17.535 mm Hg, about 0.,023 atmosphere. In a sealed system - with air and other non-condensible gases excluded - this is quite enough to drive rapid circulation

Which could spin a turbine.

I just wonder why we are discuss various fluids, when the whole
concepts of such power plants are flawed.

Due to the very small temperature difference (20 C) the Carnot
efficiency is quite lousy, from 27 C to 7 C only 6.6 %.
https://en.wikipedia.org/wiki/Carnot_cycle

If you move the cold end below the thermocline (several thousand
meters) you will find +2 C water and gave a \'huge\' temperature
difference of 25 C and a Carnot efficiency of 8.3 %.

Some of the advertising pictures put the floating plant close to an
island, but at such places the ocean is too shallow and there is not
any real cold water even at the bottom. You need to move the plant
into deeper waters.

A big plant need to be placed in a place with a good stream of warm
water on the surface and a cold stream several thousand meters below
surface. This is essential to main the temperature difference, since
extracting (electric) energy tend to reduce the temperature difference
in that part of the ocean. It is no point putting the power plant into
a calm lagun.



To extract more power on the oceans, some forms of evacuated tubular
collectors could be used. These could float on waves and create
temperatures well over 100 C, thus a Carnot efficiency over 27 % could
be achieved.

And you could even use water as a working fluid :).

If the heat input is free, you don\'t care about the efficiency. The real problem s that the heat is pretty diffuse, so the capital cost of putting the hardware in place to collect the energy is excessive.

All correct, and all wasted on a a, who is a gibbering idiot. Pointing out where he has posted total nonsense might humiliate him into silence it he has enough sense to realise that he had posted nonsense, but he\'s the same kind of over-confident half-wit as Flyguy, who never realises quite how obviously foolish he is.

This is a non-sequitur. The ocean provide a quasi infinite amount of
heat. Efficiency is only relevant if you supply the heat your self by
nuclear or chemical reaction.

There\'s a natural electric field above the ground, and people now and
then raise money to use it.

There are a bunch of recurring money-raising schemes:

Trains in evacuated tunnels.

Supersonic passenger planes

Vertical takeoff/land passenger planes. Very popular just now.

Electric airplanes.

Solar thermal towers

Ocean thermal power genertion

River- and ocean-current power generation

Ocean wave power generation. Waves are free!

Airships

Cars powered by steam or Sterling engines. Or even batteries! Or
Hydrogen!

The Hydrogen Economy. Sunlight and water are free.

Flying cars

Rooftop residential wind turbines

Gravity enegy storage (solid mass, not pumped hydro)

Kite power generation

Bladeless wind generators of various sorts

Sailing ships

AI.


I may have missed a couple.

Electric motorcycles? Noiseless choppers will never sell.

Bowling ball energy srorage?

Giant spring energy storage?

That\'s fraud,

There are a bunch of recurring money-raising schemes:

Trains in evacuated tunnels.

That actually makes sense, but only for extremely busy routes, which don\'t seem to exist.

> Supersonic passenger planes.

Practicable, but turns out to be too expensive to be practical.

> Vertical takeoff/land passenger planes. Very popular just now.

They\'ve been around for ages, as helicopters. They seem to crash a little too often for comfort.

> Electric airplanes.

It\'s not exactly recurring. More or less the same one has been flying around for years, and getting tweaked from time to time

https://www.nasa.gov/centers/armstrong/news/FactSheets/FS-034-DFRC.html

> Solar thermal towers

They stopped being attractive when solar cells got cheaper and more efficient about a decade ago

> Ocean thermal power generation

Cute idea but impractical.

https://www.google.com.au/books/edition/Engineers_Dreams/2l7bAAAAMAAJ?hl=en

> River- and ocean-current power generation

It\'s called hydroelectric power and it is tolerably practical. Ocean currents don\'t seem to be fast enough to do the job.

> Ocean wave power generation. Waves are free!

But they get big from time to time and break your machine.,

> Airships

Perfectly practical, but a bit slow.

> Cars powered by steam or Sterling engines. Or even batteries! Or hydrogen!

They all work. Batteries seem to work fine. Hydrogen seems to be a bit impractical, but the hydrogen economy enthusiasts like it.

> The Hydrogen Economy. Sunlight and water are free.

Electrolysers aren\'t. You get about three times as much range out a battery than you get from the same amount of electric power turned into hydrogen.

> Flying cars

Always a silly idea.

> Rooftop residential wind turbines.

I\'ve never seen one.

> Gravity energy storage (solid mass, not pumped hydro).

Might work.

> Kite power generation

Doesn\'t seem to work.

> Bladeless wind generators of various sorts

Never seen one. Aerodynamics experts get turned on by the idea, but it seems to be more cute than practical.

> Sailing ships

They do work, but not all that well.

> AI.

Real artificial intelligence works fine, but only in specialised applications. As snake oil it does seem to suck in gullible suckers.

I may have missed a couple.

Electric motorcycles? Noiseless choppers will never sell.

Except that they sell fine, but not to hairy bikers.

> Bowling ball energy storage?

Now you are being silly.

> Giant spring energy storage?

It\'s called compressed air energy storage. If you have a big air-tight underground cavern it could work.

My name is Maggie Lawson, and I am very enthusiastic to join the Internet of Think study program at STIKOM University. I am very interested in the world of technology and how software can help solve real world problems.

Since young, I have had a passion for programming. I started learning my first programming language at the age of 18, and since then, I have never stopped learning and developing my skills. I\'ve worked on several small projects and worked on several applications https://ateliersansfrontieres.org/, which helped me understand the software development process from start to finish.

I am very interested in learning concepts like web development, mobile app development and database management. I also believe that collaboration is the key to creating great software, and I am passionate about working in teams to tackle complex challenges.

While at university, I hope to deepen my understanding of various programming languages, software development methodologies, and also understand how to solve problems in software development effectively. In addition, I plan to engage in group projects and practicums to gain deeper practical experience.

Outside of academia, I enjoy exploring side projects, learning about the latest trends in the tech industry, and participating in developer communities. I also believe that continuous learning is the key to staying relevant in the rapidly changing world of technology.

I really enjoyed meeting my classmates, lecturers and professionals in the software industry. Let\'s explore this exciting world together and collaborate to create innovative solutions.

This isn\'t a particularly academic user group, and any thread started by a a is likely to be less academic than most. He seems to be a Chinese propaganda bot.

Look out for Phil Hobbs. He\'s more academic than most, and better informed. Whit3rd is pretty good too;

That\'s the pattern nowadays, kids want to type and not solder. But the
world is still analog.
