I've got a plan based on self-replicating swarm robots. The basic idea is to collect oceanic trash and recycle it into more robots (to collect more trash to make more robots, &c.) The geometric increase should allow for a (relatively) small "kernel" to grow to handle the global problem.<p>Two primary recycling technologies seem promising: Thermal Depolymerization and Molten Salt Oxidation.<p>I've acquired two boats, one to serve as a base and the other to get to/from it, and I hope to begin collecting trash (in SF bay to start) this summer. :-) <i>Fingers crossed...</i>
