#2Very cool idea. Probably wouldn't want to do it where there is marine life though.

#3What is it about Soundwaves that allow plastics to move in a direction?

Agreed, so cool! And good point. Here's to finding a way to keep micro-plastics out of the ocean altogether, for the sake of marine life, humanity and the planet.

Generally, there is not marine life in the drain line of a washing machine.

Resonant waves in a liquid can cause particles of different sizes to move toward the nodes or anti-nodes of a standing wave. A secondary effect is the particles can conglomerate and fall out depending on density.

#8I use a Cora Ball [1] in my laundry for the same purpose. Studies say it is only 26% effective, better than nothing.

Amusing but I think aiphex was considering the possible reuse of this tech against the pacific gyre.
If we cut off the microplastics at the source then the gyre will eventually take care of itself. The problem right now is that we’re continually adding more and more pollution.

#10Or we could stop making clothes out of materials that shed microplastics. And while we're at it, cotton too for the vast amounts of water it uses. Industrial hemp and linen are far more sustainable options. Tencel looks like a great replacement for cotton and uses wood cellulose.
