Brian von Herzen is an expert on seaweed. He is creating platforms in the ocean that are farms for kelp. Wave-powered pumps bring nutrients up from the depths to enable the seaweed to thrive, and around them are vast numbers of fish, that come “for the good stuff” the seaweed provides. About a quarter of the plants fall off and sink to the bottom of the ocean, taking with them carbon from the atmosphere that will be sequestered for hundreds of years. The rest of the seaweed is sold for food, fertlilizer, and other compounds, including a bio-stimulant to be sprayed on crops to make them healthier.
