- Boyan Slat talked with Technology Manager, Arjen Tjallema, to discuss the complexities of iteratively designing and testing ocean cleanup technology in this particular offshore environment. Subscribe to our channel: bit.ly/371k8sN
Although this does entail its challenges, we aim to reach proven technology with this system, but, regardless of the outcome, the many learnings from this campaign will be applied to refining and improving our design and processes.
In four months, we designed, procured, assembled, and launched an entirely new system, dubbed System 001/B. This variation of System 001 entails modifications aimed at addressing the plastic retention issue we faced with Wilson. To learn quickly and achieve faster iterations cycles, speed is key with this design. This is how we got there and what our next steps will be.

Trash accumulates in five ocean garbage patches, the largest one being the Great Pacific Garbage Patch, located between Hawaii and California. If left to circulate, the plastic will impact our ecosystems, health, and economies. Solving it requires a combination of closing the source, and cleaning up what has already accumulated in the ocean.
The ocean is big. Cleaning up the Great Pacific Garbage Patch using conventional methods - vessels and nets - would take thousands of years and tens of billions of dollars to complete. Our passive systems are estimated to remove 50% of the Great Pacific Garbage patch in just five years, and at a fraction of the cost.

Don't give up Boyan! Your team is changing the world for the better...no greater cause!
For everyone who is interested nowadays why you are using active systems instead of passive ones, this is great to learn the background and how you came to the current design.
Feel good! So proud of your project, thank you so much for your catching up! Love ❤🙏
This is such a good idea. I would also suggest to try introducing a large number of spherical balls of different diameters that will have course velcro fingers that will attach to each other and the sides of the barrier. With openings in them that once plastics enter they can not exit. They could be light and very strong in construction (carbon fibre) but also radio controlled and self propelling to ensure they remain inside the barrier.
Love what you guys do for the planet! I actually came and watched your first launch in San Francisco last year! You guys are awesome, thanks so much!
Applauding your work from Canada. Go go go! 🇨🇦 👏
Keep going Boyan! I’ve got a suggestion... if going faster is preferred... how about adding some type of “thrusters” to the boom ends to impart a force to the system? Solar powered thrusters like bow thrusters on ships?
Activated by GPS sensors that sense a “delta” between the plastic and the system ?
This is so exciting to watch! Remember all of the effort the US Space program took to get men on the moon!!! Nothing is off the table !
Amazing work guys! Out of interest, I'm sure this has been considered several times, why does a huge floating trawler net with large floating mouth not work? Ie: A huge wide net that could be pulled across the ocean surface between two tankers .. with similar technology used by Ocean Cleanup to not catch fish etc. All the plastic would then be collected in the net - The more plastic it collects the more the net would float on the ocean surface. The net could be several hundred meters long allowing for a long voyage across the garbage patch. 😁 In contrast to the first prototype, it would not be autonomous. I find these ideas fascinating. 👍 Great work. 😁👌
Would it be possible to have an in-built container travelling with Wilson which collects plastic along the floater every day? It seems that the problem is to retain plastic over a number of days, not so much to capture it for a couple of hours?
This is an option we might consider in the future, although we’d prefer to have a system functioning without such addition and would also add quite a bit of complexity.
That would likely create variable drag and probably change the dynamics of the movement of the system

Hey Boyan Slat:
Have you heard about Fionn Ferreira?
He is from Ireland & just won the Google Science Fair for his idea of using ferrofluid to remove microplastics from water.
Very nice catch! The one day we read about how microplastics are floating at larger depths, and we imagine that it would be almost impossible to clean it up, but then we read about iron oxide acting like a magnet to microplastics and hope returns!
He was using a well know and understood flocculation method patented and owned called Sirofloc it is used in many water treatment systems around the world. I'm sorry to inform you that what he showed is nothing new.
@@snsn8252 Well it is a shame that such a method exists but isn't used to clean up the oceans... In a way the fact that this kid made more people aware of it is pretty good, maybe now more people will connect the dots...
@@otinane89 The application of it requires the surface charge of the magnetite to be positive this only really happens at below 6 pH. Oceans are usually 7.7-8 pH which means the surface charge isn't positive. PP and PE are generally negatively charged above 2.5 pH sure to dissociation of carboxyl groups that arise during polymerisation or later oxidation.
@@snsn8252 So there is no way to apply it in ocean cleaning?
Speeding up will cover a much bigger area and much more plastic. Keep that in mind too.
Keep in mind that in the Gyre, the current is circulating and either approach will cover similar amounts of ocean surface area. Because of this they had once considered anchoring the system to the ocean floor and letting the gyre rotate through it.
@@denniskix5471 i doubt, because the important variable is not the speed over ground (gyre) but through water.
@@Largexxl-zn4lx good point. The speed over ground would only be important if they were still trying to anchor the system to the ocean floor which i believe they decided against doing that.
@@denniskix5471 i missed the reason why they dont plan to anchor the system any more.
@@Largexxl-zn4lx much too deep. It is just not practical.
great work and cheers to you all from Canada 🙋♂️🍁😊
Will you be doing it on other oceans or seas in the future? Amazing job so far, thank you from the bottom of my heart ❤
Yes we will scale-up to other oceans in the future.
Thank you from Thailand 🙏
Thank you from Italy!
keep going! please implement it worldwide
I need to iterate on this video to be able to understand it.
Please summarize your finding (perhaps add them after filming) every 4-5 minutes or so. i.e. *Plastics are moving faster due to currents*.
Also 'basic' definitions such as Fenders, bouye's & images.
Already great job though!
Keep going, you gonna crack that nut!! And let always drive the solutions with facts, like the waves do ;)
how about collecting the plastic where the big rivers flow into the ocean? Easier to reach and plastic doesnt reach the ocean.
I also understand countries like the Phillipines are the worst plastic waste emitters into the ocean (please correct me if I'm wrong) - and based on coastal, rather than river - emission, this again would be impossible to prevent, unless aggressive governmental policies severely limited plastic usage at the outset.
Thats another problem to be solved.
What they are doing here is trying to get rid of the plastic that is already in the ocean. There are different projects for different parts of the problem.
Prevention and cleanup must occur simultaneously. Currently, our focus is on developing a cleanup system for the five ocean gyres as the plastic out there will not go away by itself.
aeiouxs I believe the major issue is that most plastics from North America and around the world are sent to China to be recycled and if it can’t be recycled they just throw it out and that’s where it ends up in the ocean.
Thank you, thank you, thank you!
Because of the corona virus, but sometimes, I don't worry about your work or this project, aha! I think, your work will be able (always) to keep on 🙂🤗 Yeah! I meaning the ocean and the environment will have to clean up in the future 😀😍😊🙏🙏
Is your data available to be downloaded?
I hope so... I need informations on this system to work on it for my project of engineer student...
Amazing work! Is this system and it's data open source?
You can also consider anchoring of the system to the bottom of the ocean with multiple lines if necessary with floaters in attachment points to the system, you would get reliable relative movement, and also stable position; the system wouldn't drift away from the Gyre, also wouldn't pose a problem to ship traffic; the simplest solution is always the best!
GOOD JOB!! :)
Would it be possible to have an automatic control system which uses the position of the plastic tracker to retract a sort of brake?
Wow. The entire situation here is really complicated. Even if attemp to create a realistic ocean modeling test bed, it wont be an easy and straight forward analysis. Good luck👍👍, i may suggest to use/create ocean scaling testbed to carryout more analysis and studies maybe??
They performed model tests at the MARIN offshore wave basin (at least for Wilson iirc), but scaling between experiment and full-scale is not always straightforward, especially when dealing with non-linear forces and small particles affected by ripples on the water surface. Add to that the difference of an open ocean vs. a controlled test environment and the complexity of finding the right design becomes clear.
Amazing findings, keep up the great work! Have you guys thought about attaching small drone boats to the two ends for speeding up and slowing down?
Good luck!
What are you testing exactly?
Are you testing to validate the results of the computer analysis?
Are you testing the robustness of the new systems?
As it was never mentioned in the video, have you come up with any practical solutions to the theoretical challenges?
What assumptions did you make on the Stokes drift graphs and on what basis did you make these assumptions?
If you are looking for more speed, are you going to be redesigning the system to optimise for speed? For example, like a F-35B jet or a Bloodhound SSC or a sailfish or Usain Bolt.
Here is an experiment for anyone to try so they can understand and experience the speed issues discussed. It is of course a primitive extrapolation and ignores most of the real issues. But it may help your understanding. Select a rubber tube, a bike tube will do, attached weights along it with a small net attached between all the small weights. Then experiment with height distances in a bath tub using polystyrene beads to replicate the plastics, use a hoover in reverse mode to emulate wind and wave forces. You will then see how hard it is to keep the beads within the scope of the tube. This is a very hard problem to solve. Good luck to them.
When are u guys going to clean the Great pacific trash?
Seria excelente ter a legenda no vidio!
How small of a particle can we filter from the ocean without harming plankton or other small important life forms and what is used ?
First of all, Boyan, great work and my huge respect for this amazing vision to clean up the oceans!
I have a question regarding the System design though. If I remember correctly, in an early video you mentioned the plan to design the collection-system the other way around: by being a little slower than the surface current, so that the plastics will be caught when it reaches the system (because it is directed backwards). I did not quite understand, why you now want the system to catch the plastic instead, leading to these effects, that the plastics outrun the system. Was there a major flaw in the earlier system design that I am not aware of?

Do it for good! Do not be tempted by money!
When discussing the graphic you both can see, it would be advantageous us to be able to focus on that mainly, rather than the two body languages if that makes sense :)
Maybe pull the ends together with a winch and temporarily seal up the system when wind-speeds are not consistently sufficiently high for prolonged periods of time?
🙌🙌🙌
Why don't you use a tiny sail ship in front of the system? Just like your drift anchor but in the air. It could use the higher wind velocity above the water.
Our ocean System is designed to follow the specific currents that feed in to the gyres. A sail would catch wind, which would potentially blow the system off course.
Anyone got a link detailing secondary drift mechanics?
They should test it, simulating all behavior of ocean, winds directions speeds, change, waves, storm, rain, all condition even small and put all together.in one equation, so when get out the ocean, they already knows 80% of device behavior
Al een bestaand system is de combinatie van windvane besturing en Jordan droque's. Parachute, werkt niet.
Bestudeer de storm survival systemen op zeilboten, met een mast op van 10 meter, zonder zeil, kan je al snelheden bereiken, Al om, aan de uiteinde van het systeem een windvane 'roer' installeren, en een droque aan ieder uiteinde...
Coloca legendas pessoal
Add funnel traps , cindtrifical force
Or what about if instead of removing the plastic out of the water, Wilson treats the plastic with some kind of eating plastic bacteria like Ideonella sakaiensis 201-F6.
I don't understand why the currents at the surface would be faster than the winds at the surface, if the winds are what generates the current in the first place. I'd imagine the "slowest wind" is a bit faster than the "fastest current".
04252020 Review 😏 Parachute net can capture and seal into itself, smaller particles & material matter of content.
Fantastic effort by Boyan and co. But I wonder why there is not more cleanup done near the sources - I think there are a few big asian rivers feeding the garbage into the oceans. So why not collect directly there? (Edit: I do not mean that the ocean cleanup should do that as well, but somebody should)
Interception of plastic at the source is an important part of the solution but must occur simultaneously with cleaning up the plastic already in our oceans. Currently, our focus, is on developing a cleanup system for the five ocean gyres.
Im sure they're on that as well. One thing at a time
@@chadstone9561 What makes you sure 'they're on that as well'? The 'One Thing' is taking some time and expense. Meanwhile, plastics of every size and description continue to enter the ocean via numerous sources, including rivers of every continent.
@@johnmorris482 most of the plastics are coming from water sources and outlets in the asian countries and India, which is foreign waters. Im sure theres alot of red tape that would have to be dealt with to set this up in those areas
Interchange book brought me here
🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷
For me it's contradictive that the wind on the water surface is nearly still when the water is in the very same spot fast.
There's friction when the flowing material drags against a more dense material. For air, that material is the water surface. For water, that material is the bottom of the ocean. There's nothing slowing down the water at the surface.
@@electroplaque Alright, it's because of the density. Thank you!
why not use more videos outside the office?
They've done many, this just doesn't call for that.
As a monthly supporter of this great project, I still believe now at the drawing board several options still should be investigated e.g. like adding ruclips.net/video/iFTToTsJuY0/видео.html to the ends of system 001/B = System 001/C?
Based on our data and simulations, it is possible to design the system to be completely passive. Adding propulsion would require a large amount of additional technology to move technology of our size (this would also impact the weight of the system). It would also add quite a bit of complexity and would require ongoing control software and technology maintenance. However, it is not out of the question.
Can you please send me your web sight so I might help financially.
Absolutely! You can donate here: theoceancleanup.com/donate/ Thanks for your support!

You MUST team up with 4ocean in the future
idea: i know its more tech than but lets destroy that idea.
solar cells on top and on the ends maybe slow rotating electrical propeller so thy safe engergy to speed up or turn the system?
I had that in mind to men but you said it first
I wish more people would donate to you instead of worrying about plastic straws.
But if people stop using plastic straws, theres less plastic in the ocean! hmmmmm
@@cholloway0046 Congratulations! you are .0000000000000000000000000001% closer to cleaning up the ocean!
Would be way more effective starting a recycling program instead of focusing on 1 tiny product out of millions.
Like trying to get sand off a beach by carrying 1 grain of sand at a time. Dream larger please.
@@looneyflight changing people's attitudes to using plastics costs nothing, and has been proven beneficial time and time again. For instance charging people extra for one-use plastic bags.
@@cholloway0046 i'll use whatever bag. I always take them back later. Grocery store near my house has drop off for plastic bags.
Still messaging way off on the straw thing. Pointless to laser focus on such a small thing. A wider net would be more effective.
@@looneyflight large change comes more slowly. Plastic straws are just one incremental change towards becoming more sustainable. (Same thing with plastic cups)
I angry with you because you thought I did not to watching your videos or not to take care about your post or not to take care of you on last night and everything I had to saying! But I always still love you, You okay? 💖😊🤗
Just want to say, I wouldn't or don't like to you have to present who or anyone to me 😶🤨 because I (usually)like to be a high personal and I think, I don't like to know about that or anyone (I just think, everything! not need for me 🙂)
I want to tell you, Now! May I have to search of the number(telephone) because I must be telephoning with the car for wash of the bathroom 🙂 Love u all the time, be right back! 😊😇 (2- 3 minutes)
explain to me why a state the size of Texas contributes 3.3 billion dollar year to their community, and yet a patch the size of Texas cost three times that to clean up? Sounds like someone is full of shit
I don't understand their sound, fact driven approach. Can't we just blame the immigrants and move on? 😇
Imagine how much plastic they could have cleaned already if they had just use nets to catch it like fish. A proven method that actually works unlike this nerdy fantasy.
WHY DO YOU HAVE TO ADD BACKGROUND MUSIC ITS COMPLETELY UNNECESSARY
