Be warned, however, no such thing exists in the real world. While the project received an honorable mention in the 2014 eVolo Skyscraper Competition, be aware that what is being proposed is extraordinarily ambitious and difficult. When I wrote about a similar project, Boyan Slat's concept for floating automated ocean clean-up arrays, I quickly became aware of countless experts who were deeply skeptical of these end-of-pipe, magic-bullet solutions to such an intractable problem as marine plastic pollution. From the harsh marine environments to biofouling to the relatively fragile nature of zooplankton, their criticisms were as numerous as they were convincing. I'd love to see the Seawer prove them wrong, but I won't be holding my breath.
