The biggest change is the switch from a moored system to a drifting system; catching the plastic by acting like plastic. We learned this has many advantages: higher plastic capture efficiency, reduced deployment- and maintenance cost, reduced risk of damage due to lower forces on the system from wind, waves and current to name a few.

From the North Sea Prototype, our largest test as of yet, we learned about the dynamic behavior of a cleanup system in the open sea. We also learned how to assemble, install and operate such a system.

We have designed a much more robust and effective system based on the learnings of our studies and tests. It is not perfect yet, but it will be at a good point to start the iterative process of testing and improving the system in the Pacific Ocean.
