Can Seaweed Save the World: Carbon storage in the homes and cities of tomorrow

The video explores the potential of using seaweed as a sustainable building material. Adam Bumpas and his team face challenges with seaweed bricks but discover a solution using potassium silicate and hydroxide. The video highlights the environmental benefits of seaweed, including its role in reducing carbon emissions and its potential in various industries. The discussion emphasizes the importance of sustainability and the potential of seaweed to combat climate change.

What was the main challenge faced by Adam Bumpas and his team in creating seaweed bricks?

• Seaweed was too expensive to use.

• Seaweed was too fragile to form bricks.

• Seaweed was not available in sufficient quantities.

• Seaweed expanded when in contact with solutions.

Which solution was found to minimize the expansion of seaweed in the brick-making process?

• Sodium chloride and calcium carbonate

• Potassium silicate and potassium hydroxide

• Magnesium sulfate and sodium hydroxide

• Calcium silicate and magnesium hydroxide

What potential benefit does the new seaweed-based building material offer?

• It is more expensive than traditional materials.

• It is a high-energy material.

• It is a cement-free, low-energy alternative.

• It is less durable than concrete.

How can seaweed help reduce greenhouse gas emissions from cattle?

• By increasing their appetite

• By reducing their methane production

• By making them grow faster

• By improving their digestion

What is one of the broader applications of seaweed mentioned in the video?

• It can be used to create synthetic fabrics.

• It can be used to power vehicles.

• It can help clean polluted water.

• It can be used as a substitute for plastic.
