Originally designed by:- The Dolos was designed in 1963 by a South African harbour draughtsman Aubrey Kruger, and were first used on the breakwater in East London, a South African port city. They work by dissipating, rather than blocking, the energy of waves. The Xblocks are based on Krugers design.

The tetrapods remind me of anti tank blocks used in WW2 , very interesting video thankyou !.

[dogcakewog]

Oh man these long breaks in between sentences is giving me ptsd flashbacks to the days in high school when I fell asleep to education video the teachers played.

[garymiller]

You produce absolutely awesome videos. Interesting, well thought out, professionally made. Keep up the great work. I always look forward to your new releases 😊

Imagine cutting and stacking 2.3 million granite blocks weighing up to 20 tons each, but without using any heavy machinery or cutting tools more durable than bronze.

This feat supposedly took twenty years to complete in the construction of the great pyramid.

Incredible feat to accomplish with or without today's heavy machinery/tools

What about using those TetraPods off the FL coast (etc) to slow down waves and such from hurricanes?

[reonvanwijk]

Kruger took inspiration from the configuration of spinal column bones. Legend has it that he was eating lunch at work, which consisted of ‘leftover’ oxtail stew. The design is ingenious in that the more the waves move the Dolos the tighter they interlock. He was originally working on a design to build a safe harbour for resettlement of the island of Tristan da Cunha after the devastating volcanic eruption that destroyed the original settlement on the island. He received no royalty for his design since he was working for the government harbours department. The design was not patented and was freely available for others to subsequently copy over the decades. Re: Wiki - ‘The dolos was invented in 1963, and was first deployed in 1964 on the breakwater of East London, a South African port city.’

Keep those awesome videos coming nice work thank you

[milesaway]

Is there any rebar used inside the tetrapod?

[jessrichardmoransee]

Excellent programs thank you and happy Easter

[cyclonicleo]

Even better are systems that allow for marine habitat to form under the wave surface. Not only do these then allow for a more natural approach but marine ecosystems are created, and heck, recreational fishers can throw a line out for a catch!

[kirkwilliams]

Thanks for sharing this teaching with us, I learned a lot.

[aussiedanjones]

I wonder what the overall effect will be with silk movements. Will this design allow silt to move more freely so it doesn't clog River entrances up, or will it allow more in broad to build up?

[hellskitchen_orchestra]

I have one tetrapod at home and it protects me against the ocean

[juvanmagsayo]

Thanks for interesting videos give more knowledge Water Breaker also known as (TETRAPODS) unfamiliar.

[kenheise]

Called them sea jacks when we lived on Okinawa in the early 80’s.

[anilshirsat]

It just resemble the molecular structure of Methane 😊
SP3 hybridization for stability. 👌👍

[ozcandurmusoglu]

You say tetrapod but show dolos more than tetrapod😅

[markusdecimus]

Best u can see is in Constanta harbor in Romania. 20 t stabilopods. Most efficient stuff against storms.

another example of how our race is using tech and know how to control our environment and tame nature
