The Ocean Cleanup

Problem: The plastic is not static, it moves around. 

Problem: Oceanic 'Garbage Patches' are huge, and cleaning them up would result in huge amounts of by-catches.
Furthermore there is a huge variety in debris sizes. 

Solution: By using floating booms instead of nets, much larger areas will covered.
No mesh means that even the smallest particles will be diverted and extracted. No mesh - together with it's low speed - will result to virtually no by-catch.

Problems: A clean-up operation would generate significant emissions. Besides that, in high seas much plastic would escape.

Solution: The platforms will be completely self-supportive, receiving their energy from e.g. the sun, currents and waves.
And by letting the platforms' wings sway like an actual manta ray, we can ensure contacts of the inlets with the surface, even in the roughest weather.

Problem: Conventional clean-up ideas have never been financially realistic, let alone remediation of millions of square kilometres.

Solution: This concept is so efficient, that we estimate that by selling the plastic retrieved from the 5 gyres, we would make in fact more money than the plan would cost to execute. In other words; it's profitable.
