Seaweed: The food and fuel of the future? - BBC
Seaweeds are fast-growing algae. They utilise energy from sunlight, and take up nutrients and carbon dioxide from the seawater. Scientists suggest seaweed could help fight climate change and offset carbon emissions.
Ocean Rainforest recently won funding from the US Department of Energy to build a similar system in California, where there's interest in developing industrialised seaweed production for future biofuels.
Aboard the harvesting boat the skipper controls a mechanical arm that lifts lines from the water. The seaweed is chopped free, filling up containers. It's quick but messy work. The lines are then left to regrow. This year around 200 tonnes will be harvested.
