Deep-sea debris retrieval powered by a single wheel
Yo-yo style descending nets collect plastic waste at depths unreachable from shore. Energy-efficient, deployable from small boats, and designed for the massive challenge of ocean plastic pollution.
You're on a small boat watching the compact unit descend — the net spirals down like a yo-yo into the deep blue. After 3 minutes, it powers back up with 50 pounds of plastic bottles and ghost nets, emerging clean and dripping, while the single-wheel mechanism hums quietly. It's like watching a deep-sea fish emerge, but it's bringing our trash back to the surface.
