I'm also curious about wave glider technologies. https://www.liquid-robotics.com/wave-glider/how-it-works/ https://www.liquid-robotics.com/wave-glider/how-it-works/ It uses an under water "kite" to harvest the wave energy for propulsion. I imagine using these for ocean cleanup. Like scooping up all the great plastic gyre debris (or whatever we're calling the floating plastic). Remember those river clean up barges? Make ocean faring versions. Use the wave glider tech for navigation and station keeping.
