太平洋西北國家實驗室的FMC-TENG是一種圓柱形摩擦納米發電機，可以將能量從波浪轉化為電能，為海上設備提供動力。
它旨在克服其他摩擦電納米發電機 (C-TENGS) 的問題，並且依賴於科學家稱之為摩擦電效應的相同過程。
它被設計成看起來像圓柱體中的圓柱體。
較小圓柱體的外部和較大圓柱體的內部都有人造毛皮塗層。
它還塗有一種稱為氟化乙烯丙烯 (FEP) 的類似聚四氟乙烯的材料。
當內筒相對於外筒自由轉動時，產生靜電並被電極收集。
FMC-TENG 是獨一無二的，因為很少有高效的波能轉換器能夠從低頻海浪中產生大量能量。
Q:波浪能與其他形式的可再生能源相比如何？

Q:那些地區正使用FMC-TENG
Chat YouTube:
目前似乎還沒有公開的消息顯示哪些地區正在使用FMC-TENG。
FMC-TENG是目前處於研發階段的新技術，Pacific Northwest National Laboratory正在進行各種測試和優化，
以確保其在實際應用中的可靠性和有效性。
一旦FMC-TENG被證明是可行和可靠的，它可能會在全球各地有許多不同的應用領域，特別是那些需要在海洋或其他水域環境下使用電力的領域，例如海洋監測，海上交通，公共事業和科學研究等領域。
Q:Wave Line Magne與FMC-TENG.有何差別
Chat YouTube:
Wave Line Magne與FMC-TENG有一些區別，它們是不同的技術。
Wave Line Magne是一種利用水波能源的發電設備，
它是一根柔性長桿，在水中懸掛並被釣在海底。它具有磁力發電機、高壓和低壓室以及一個水泵。隨著海浪的起伏，長桿彎曲並產生能量，該能量被傳遞給發電機並被轉換為電能。 Wave Line Magne是一種低成本、低維護、長壽命、高效率的新型波動動力發電技術。
而FMC-TENG則是一種利用靜電產生電能的新型發電機，
它是由兩個圓筒組成的，外層圓筒採用人造毛皮塗層，內層採用塗有氟乙烯丙烯（FEP）等材料的電導材料塗層。當內部圓筒自由旋轉相對於外部圓筒時，靜電電荷被產生並被電極收集。 FMC-TENG整個發電過程都是基於靜電的發電原理，而且只能利用水面上震動和運動的波浪能量來引導內部圓筒的旋轉，從而產生電能。
因此，
Wave Line Magne和FMC-TENG缺點和優缺點不同，
應用領域也有所不同。
Wave Line Magne適用於需要在水中進行電力發電的應用場景，
而FMC-TENG適用於需要在海上利用波浪能量進行電力發電的場景。

When it comes to renewable energy, you must have been hearing a lot about wind, solar
0:04
power and of course lithium-Ion batteries.
0:07
Did you know, wave energy is quite a rage among industrialist looking for improved sources
0:12
of sustainable energy?
0:14
I’m not speaking about the Mexican wave here; I’m talking about the waves in the
0:18
ocean and one company is currently making waves on the renewable energy scene with wave
0:22
power.
0:23
Pacific Northwest National Laboratory (PNNL) researchers have now developed a new cylindrical
0:30
triboelectric nanogenerator that is one big powerhouse that will power devices at sea
0:35
by converting the energy from waves into electricity.
0:38
Sounds cool right?
0:40
But before I tell you more, why don’t you click on the notification and subscribe to
0:43
this channel.
0:45
Now let’s get it on.
Wave energy, the new carbon free source for renewable energy
0:51
Pacific Northwest National Laboratory is one of the leading research centers for R&D in
0:55
sustainable energy, analytical data, chemical discoveries and Earth science.
1:00
The new cylindrical triboelectric nanogenerator which they like to call FMC-TENG, is one awesome
1:06
baby that is about to redefine the way humans use wave energy.
1:11
Powering devices at sea to collect data will be a no brainer for this new process, and
1:15
besides that, researchers say that larger versions of the generator can also be built
1:20
to power ocean observation and communications systems, including acoustic and satellite
1:25
telemetry.
1:26
It has great potential to improve the process of wave energy and make it even more eco-friendly.
Ocean Instrumentation, A billion-dollar industry
1:31
Now wave energy is considered one of the most promising forms of renewable energy.
1:35
It is an amazing alternative to fossil fuel energy that releases all that toxic carbon
1:41
emissions into the atmosphere, it’s really hurting mother earth.
1:45
Humans desperately need to find more and more ways of generating eco-friendly energy or
1:49
else climate change is going to be driving us crazy one day, in fact it already is if
1:54
you ask me.
1:55
Natural resources like heat, wind, solar and now wave energy need to become the in thing,
2:01
the trend of the day.
2:02
Marine scientists use a huge amount of electricity to power up data devices and for sophisticated
How Does Wave Energy Work?
2:08
marine technology.
2:09
Ocean instrumentation is quite an important part of life.
2:12
Without such devices, we would never be able to monitor the movements of the oceans, ocean
2:17
currents, tsunamis, water levels and the like.
2:20
You wouldn’t be getting whether updates or when there is a hurricane approaching.
2:24
The problem is that ocean devices lie unattended and depend on battery capacity for data storage,
2:29
and transmission to shore.
2:31
If marine energy were to meet the needs of powering these devices, that would be a godsend.
2:37
Marine energy could provide a huge advantage at-sea power generation including colocation
2:42
with ocean.
2:43
Heck, Marine energy could also be used for generating power to small devices used in
2:47
defence applications too.
2:49
There is world of possibilities and that’s where PNNL’s new generator will make a phenomenal
2:54
impact, now do you see the connection?
2:56
But how exactly will wave energy be harnessed?
3:00
The process is not a complex one and is similar to all processes using the vigorous movement
3:04
or intensity of earth’s natural elements to generate energy.
3:08
Wave energy involves harnessing the energy from the movement of waves by placing electrical
3:13
generators on the surface of the ocean.
3:15
Let’s take a look at how wave energy works.
Wave energy is always there, it will never be non-existent
3:18
In the ocean, it is tides that causes waves and that depends on lunar cycles, yes!!
3:22
it’s the moon that determines if you’re going to have a good day or a rough day at
3:26
the beach, unless you’re a pro surfer and love the rough surf.
3:29
The intensity, strength and size of tides, winds, weather, and waves all depend on lunar
3:35
cycles.
3:36
Through movement, waves rolling in the ocean create kinetic energy.
3:39
It is this kinetic energy that can be again converted into electricity and power.
3:45
Waves also move up and down as they roll along the ocean.
3:48
Energy can be harnessed from this up and down movement to power pistons and in turn generators.
3:52
Depending on the lunar cycles, tides, winds, and weather, waves can vary in size and strength.
3:53
As waves roll through the ocean, they create kinetic energy, or movement.
3:54
This movement can be used to power turbines, to create energy that can be converted into
3:55
electricity and power.
3:56
There are also several ways of harnessing wave energy that utilize the up and down motion
3:57
of the waves to power pistons and turn generators.
3:58
Wave energy is also a renewable source of energy and in fact, quite a valuable one at
3:59
that because it is a permanent resource that can never dry up.
4:01
For example, even a lithium-ion battery depends on lithium deposits in the earth but as long
4:07
as the moon moves around the earth and the earth tracks around the sun, waves re gonna
4:11
be there.
4:12
We’re never going to deprive the earth of anything and neither is wave energy going
4:16
to produce deadly carbon emissions like oil and coal.
PNNL’s FMC TENG: redefining ocean technology
4:19
Now you know about wave energy so how will PNNL new wave generator take the entire process
4:25
up a notch?
4:26
The PNNL team have designed what they call an FMC-TENG or "frequency-multiplied cylindrical
4:33
triboelectric nanogenerator."
4:35
This is device built to draw power from low frequency waves out in the open ocean.
4:40
There are similar devices that use wave energy like the Cylindrical triboelectric nanogenerators
4:45
or C-TENGs which has been designed for low frequency wave energy harvesting.
4:50
But it has its challenges.
4:52
To operate, a C-TENG needs uniform , low amplitude, and low frequency water waves even in the
4:58
middle of the ocean.
4:59
PNNL’s FMC TENG has been designed to overcome the problems with C-TENGS and depends on the
5:06
same process of what scientists call the triboelectric effect.
5:09
Sounds complex to you?
5:10
Well, to put it in simple language, it’s the same effect that causes static shocks
5:15
after you walk on certain carpets.
5:17
Current theory says this occurs when two dissimilar materials exchange electrons at the molecular
5:22
level, resulting in an electrostatic attraction.
5:25
When two materials are rubbed together, their electrons are efficiently separated before
5:29
they can return home, leaving a charge.
How the FMC TENG works
5:32
The FMC-TENG has been designed to look like a cylinder within a cylinder.
5:37
The exterior of the smaller cylinder and the interiors of the larger one has an artificial
5:42
fur coating.
5:43
It is also coated with a Teflon-like material called fluorinated ethylene propylene (FEP).
5:49
These are materials that re selected to optimize the triboelectric effect when rubbed together.
5:54
When the inner cylinder rotates freely relative to the outer cylinder, static electricity
5:59
is generated and collected by electrodes.
6:02
Now as I mentioned before, such machines have been built, but what the PNNL team needed
6:07
was to amplify the output by magnifying the motion between two cylinders.
6:11
It accomplished this by magnetically slowing the inner cylinder's movement, preventing
6:15
it from rotating until it reached the crest of the wave.
6:18
The maximum potential energy at this point then releases the cylinder causing it to roll
6:23
back much faster than usual.
6:25
Thus, the triboelectric effect can be maximised by transforming a single slow-moving wave
6:30
into several faster revolutions between the two cylinders.
6:34
This improved the process increasing output to enable the machine to be more effective
6:38
operate successfully with slower, more uniform waves, such as those found in the open ocean.
What makes the FMC-TENG unique
6:44
Now it is this process that makes the TENG more efficient and capable of generating more
6:48
energy from slower moving waves.
6:51
PNNL laboratory fellow Daniel Deng, who has co-authored the research study for the new
6:55
generator says ““The FMC-TENG is unique because there are very few wave energy converters
7:01
that are efficient and able to generate significant power from low-frequency ocean waves.”
7:07
With renewable energy, the FMC-TENG could power integrated buoys with sensor arrays
7:12
to track open ocean water, wind, and climate data.
7:16
For now, the PNNL team aren’t concerned with megawatt devices that will deliver energy
7:21
back to the grid, although the new technology could be blown up to do so.
7:25
The FMC-TENG has been designed specifically to draw power from low-frequency waves out
7:30
in the open ocean.
7:31
It is being projected as a low cost, lightweight and practical power generator for ocean monitoring
7:37
platforms such as satellite communication systems, and ocean sensors.
Several sophisticated applications now possible with the FMC-TENG
7:42
The FMC-TENG could also replace the need for cabled power to even more sophisticated marine
7:47
tech like High-definition camera systems, mass spectrometers, environmental sampling
7:52
processors and robotic systems.
7:55
Not only will the new generator help man in being more aware of how the oceans impact
7:59
life, it could save life too with valuable data constantly being fed into systems on
8:04
shore.
8:05
The new generator shows promise to change the oceanic technology scene.
