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.

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.

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.

Your statements make no sense since water is not the working fluid, see above.

As breakthroughs go, it's hard to get excited about a scheme that was described in detail in Willy Ley's "Engineers Dreams" published in 1954.

https://archive.org/details/engineersdreams0000will/page/n3/mode/2up

There's not a lot of temperature difference to play with, so you don't get a lot of kilowatts out of your capital investment, and the equipment has to be robust enough to survive a hurricane. Not an attractive proposition, if undeniably cute.

You are conversing with Darius the Dumb. I've clipped your statement
above at the most accurate point where it relates to Darius the Dumb.

Darius the Dumb simply cannot "understand the process". With an IQ of
about 25, Darius the Dumb is incapable of understanding anything much
more complicated than: "fire hot".

You may as well quit while you are ahead, as trying to educate Darius
the Dumb will only result in much frustration for you, and no increase
in IQ for Darius the Dumb.

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?

Kinda pituful, four hours of 16KW on a ship. Net power gen effiency

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.

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

you said:

" 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 vapor at +20 degree C (room temperature) has no pressure

to drive any turbine at all

Go to school to get your tuition fee back.

Your statements make no sense since water is not the working fluid, see above.

https://en.wikipedia.org/wiki/Boiling_point

Water is not a working fluid in either case !!!!

If you are mind sick, get a medicine

and start to study the physics of evaporation.

Water has no -30°C boiling point at all !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.

Stop posting as such an abject idiot and no one will have any reason to
nickname you "Darious the Dumb".

But, given your post history here where you have authored the content,
your IQ level is realy hovering around 25 and you are simply not
intelligent enough to post anything coherent.

Therefore you will be incapable of posting intelligent statements, and
will continue to be named "Darious the Dumb".

Ocean thermal energy conversion (OTEC) is all about electronics and physics.

Who cares lazy guys generating spam traffic

This group is not made of R&D, scientists
so what I publish represents state-of-the-art in technologies for the record
and I don't care comments by low-minds

"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.

Geothermal is tough enough to implement without bringing that corrosive wind-swept ocean into it:

China is doing it too:

The OTEC thing must be a job-fare program.

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.
