Phykos’s carbon-capturing robotic seaweed farms are like planting fore

Good News Notes: “A new prototype of a small, solar-powered robotic vessel recently started sailing in the Pacific Ocean, pulling an underwater rack filled with seaweed. The startup developing the technology, called Phykos, says each platform holding the fast-growing kelp may be able to capture as much CO2 as 250 trees—and though the approach still needs…
