Scott continues: "So the idea is that these little bots, roughly the size of an automobile, skim the ocean's surface in each of the five trash gyres. The plastic, already broken down by UV, is collected, melted, and then formed into a ball which is then filled with hydrogen and released into the atmosphere. Over time, the hydrogen dissipates and the ball returns to the ocean’s surface where it eventually finds its way to coastlines (and clean-up crews) all around the world. I call it the most poetic homecoming ever!"
