System 002 - Concept and Design | Cleaning Oceans | The Ocean Cleanup

System 1B was run, get out there as fast as possible to prove that this technology strategy we have, so passive float of systems, that actually works and is something we can build on for the future. So with system 1B, well mission one you can say now concluded, the focus of the team shifted to system number two. System number two we want to be full scale in size, so basically scaling up the technology itself, but also looking at fully operational. So that means our engineering team is now focusing on two main engineering parameters. One is long-term operability, the second part is the sustained plastic retention. This means we want to find a method for the system to hold plastic in the system longer, so we can actually optimize our extraction model and therefore lower costs and then vessel impact on our mission. So those are the two parameters our team is working on at the moment, but it also means we're going to have a few design updates in our system to address these two points. What we realize is that the main cost of getting plastic out of the ocean is vessel cost. So ideally you have systems out there that can just stay there for months and months and months at a time, maybe a year even, and you just periodically have to visit to extract the plastic. So capturing is one thing, but retention, that's really what's required to be able to do that. And you'd much rather have perfect retention and sub-perfect capturing than sub-perfect retention and perfect capturing, but that's what we hope to do in the run-up to system two. Always building new stuff. We're in the zoo today, where we have some basins to do some little experiments. It's like really James Bond-like, like this big black screen opens up and there's this huge aquarium with sharks swimming around. Today we are going to do some tests, some simple tests, we call tinkering tests. That means we build some simple models and we put them in a pool of water, just to play around with it basically, and then we can can feed that back into the concept development. Just be sure that at least the first model is So the simpler it looks, the better of a design it is. We're investigating the different footprints and can we create a geometrical trap. We have system 001B that has caught plastic. So yeah, the benchmark is there. Curious to this one. Once they move this side, they open up. Once they move the other side, they close off each other. I mean what we're doing here is of course what we call tinkering, so we're looking, we're thinking, we're trying to come up with different ideas and hopefully it helps us in finding a good solution for the retention problem. So those of you who have been behind your computer this afternoon have seen that I've just sent out an update on the coronavirus situation. In fact, with IT, we are really looking at what is necessary. If at some case the instruction comes that we can't come to the office at all and everybody has to work from home, so we are trying to prepare for that scenario as well. Hello everyone! Hi guys, good afternoon! Hello everyone! Hello! Hello! Hello! Hello! Hey Fedde, is it me you're looking for? Welcome everybody to this brainstorm session. I took quite some time to organize it, to make sure we can work it out online. We are a big group and I hope it's gonna be a fun brainstorm and I hope that we manage to get quite some good ideas out. It can also be a big failure, it's okay. I hope we end up somewhere in between. Please just let's be honest with each other. I hope you guys can help me. This brainstorm is gonna be about the retention system, but especially regarding the intake mechanism. We want that at least 90% of the plastic that we encounter will enter the retention area. This is really an important part of the system development. Let's get the best out of it. Plastic intake from below. Yeah, maybe. Oh, I thought maybe if you have that weight then it travels along this line. More reliable way between. Oh, it's popping. And this is just a cross-section view. You follow this from left to right, you slowly dissipate the energy of the waves and you end up with a calm zone retention area. Kind of like an upside down suction pile. Can you break up the problem into smaller steps? The right barrier comes up and the left one goes down. But that only works if the rest of the structure around it is also rigid. Yeah, all of the windows have a one-way valve. Then you get a turbulent area, as we saw with Wilson's screen. It's about to hit from my side. We will take it from there. Thanks, awesome job. Bye, guys. Yeah, good job, Oli. Bye, bye-bye. Thank you. Bye-bye.
