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…

These microscopic robots swim through the ocean and dissolve microplastics

Good News Notes: “Microplastics—tiny pieces of plastic smaller than five millimeters across—are everywhere, from snow in the Arctic and rain in the Rocky Mountains to bottled water and beer. On the ocean floor, there may be nearly 16 million metric tons of it. In the top 200 meters of the Atlantic Ocean, there may be 21 million more metric…
