TetraPOT | Sheng-Hung Lee

shenghunglee.wi...
Current artificial sea defence structures tend to be dislodged over time by the force of the ocean constantly crashing against them. They have also been criticized for destroying the natural scenery along coastlines. As for natural sea defence, more than 35% of the world’s mangroves are already gone because of the greenhouse effect. We not only identified some challenges that we need to face but also found some opportunities that we’re going to focus on, e.g. Under mutual benefit/value theme, we will create symbiosis between artificial sea defence and natural sea defence.
TetraPOT is a sea defence system made of concrete. It comes with plant seeds in a decomposable pot. Randomly distributed TetraPOTs along coastlines will eventually interlock to create a long-lasting sea defence of growing trees and roots that help keep the blocks in place.
As plants grow inside out from TetraPOT, the roots will intertwine and gradually become a natural sea defense. The shape and placement will enable TetraPOTs to interlock with each other and form a structured web. The design not only prevents soil erosion, but also helps to protect and create a natural habitat. It’s not only a defence, but also an ecosystem. A home for other livings.

This looks like a really economical, sound solution to helping reprotect coastlines and the environment. Very cool.!

[@shubhashismishra2694]

Cool

[@natureareone9044]

need more modification because the hole for root it so little

[@TheDira21]

its great idea... I like it... my country Indonesia is over than 17000 Island and the largest mangrove habitat in the world..

[@johnharper5133]

I think this concept is best, it's like taking down two birds with one stone. I think this concept is best and cheaper to work with on sinking inhabited islands such as Port Adam (Fanalei) in the Solomon islands.

[@NguyenTruong-dv9jo]

I'm really appreciate what you've done. It's such a fascinating ideal

[@jontakaki503]

While the tetrapod is a french invention you never see them around in france. They ruin the see side landscape in such a way no one would ever accept their presence. The country that produce the most ridiculous amount of tetrapods is probably Japan where the construction industry reigns supreme on local politics. There's very little incentive for the majority of low skill workers that live around coastal villages to oppose the spread of tetrapods in Japan, because they would be unemployed otherwise. From mining, concrete production, sand dredging, filling the thousands of tetrapods mould with sand taken from rivers and costal areas, and finally transporting them with special boats equipped with cranes, it's a big production chain that would have to be dissolved in order to save the beaches from utter obliteration by the concrete industry.
It's sad to lean Taiwan is suffering the same fate as Japan, probably courtesy of Japan Inc. I do hope these kind of projects will have a proof of concept financed and will eventually create a new industry that will replace the current monstrosity.

I'd love to see this in Ecuador!

[@tempo4614]

Genial 👍👍👍👍👽👽👽🇧🇷

[@shekhar_sahu]

Wow. Has it been installed somewhere?

[@iizvullok]

Please make the music a little louder next time. Some guy in the background keeps talking into it.

[@tipsyswayy9045]

That can work . If trying keep eco alive n balance

I been thinking about the same solution for a while now. Has this been implemented. The coastal stretch i am trying to implement this in is in East Africa.

[@christianwolf68]

this should be pitched to every single state along the gulf of Mexico and the east coast of the United States

[@jackalwaysfaded1374]

Is there any real time applications of this being used ? It looks so interesting

[@robertcana9193]

amazing idea!

[@manta_ray720]

Hi. Is there any success Tetrapot project? If yes, can you name it? I need it for my doctoral research. Cheers

[@treelife365]

This is cool! I wonder if there are any solutions for temperate climates, as mangroves don't grow in temperate climates.

[@grdina86]

These do:

I know in NYS we have wetlands

[@JeffreyBarkdull]

Does it protect the coast from a Tsunami?

[@leanderbarreto980]

It should

[@gianni.santi.]

Have they implemented this already?

[@busterthe2]

If they are hollow it defeats the weight property.

[@aBuAraDaH]

Does it work in sement fish pool

[@sugarluv2]

How tall are they? This is so cool!!!

[@milesaway3422]

This is beautiful

[@zhongyi7211]

Can you do another video without your music FORE GROUND ? Thx.

[@loneforest6541]

nice idea...unique !

[@ikame28]

Thank you for this

[@hafezahmad3747]

nice initiatives.

[@BHMPictures]

Brilliant

[@Tom_Samad]

I would love to see these tetrapots in Bangladesh.

[@simplyme9336]

Interesting concept but you would have to make this work from every single orientation

[@alessandromauro8504]

È una soluzione bellissima

[@anandafitriananshary3312]

It's a very good concept. However, in the real world this is very hard to apply

[@johnharper5133]

I think this will work best in South Pacific countries, especially where I'm from in Solomon islands, in particularly to sinking islands such as Port Adam (Fanalei).

[@deep-fried-zombie699]

It won’t work at all.

[@shubhashismishra2694]

Good

[@manjunathakamath4601]

[@rin_box]

tetrapods are meant to move, mangroves are already natural barriers

[@Frostbyte501]

Hail tetrapod

[@CAMacKenzie]

Plastic and concrete instead of metal

[@tameracikalin3355]

To the producers of this video. What is up with the stupid background music, which renders the speech unintelligible and distracts from this great idea!

[@jaxonmckean2318]

How come nobody has mentioned trees have a hard time growing in saltwater?

[@ryanmcewen415]

Mangroves ONLY grow in salt water or brackish water. Hence why they specifically named that species.

[@rdvgrd6]

Too expensive.

Crap music played too loudly drowns out narration and makes video unwatchable. Stopped before the end.
