Can Seaweed Save the World: Seaweed farms in the open ocean

The video discusses the potential of seaweed farming to reduce carbon emissions and combat climate change. It highlights the challenges of growing seaweed in the open ocean due to nutrient scarcity and introduces a marine permaculture array proposal funded by the Australian Government. This innovative approach uses wind, wave, and solar power to access deep ocean nutrients. The video also explores the scalability of seaweed farms and their potential impact on carbon capture.

What is the estimated size of seaweed farms needed to draw down a gigaton of carbon?

• 10,000 square kilometers

• 1,000,000 square kilometers

• 1,000 square kilometers

• 10,000,000 square kilometers

What is a major challenge in growing seaweed in the open ocean?

• Strong ocean currents

• High water temperatures

• Lack of nutrients

• Lack of sunlight

What innovative solution is proposed to provide nutrients to seaweed in the open ocean?

• Using artificial fertilizers

• Introducing nutrient-rich fish

• Building underwater greenhouses

• Developing marine permaculture arrays

What powers the nutrient pumping system in the marine permaculture arrays?

• Hydroelectric power

• Wind, wave, and solar power

• Geothermal energy
