# Fabricating floating SeaBricks made from kelp to decarbonize the global construction sector while supporting vulnerable coastal communities.

**SeaBrick** is a transformative climate solution leveraging ocean kelp to fabricate 'bricks' for constructing massive deep-water kelp farms, fostering circular sustainability. This innovative approach utilizes natural resources to create a self-sustaining ecosystem benefiting the environment and humanity.

## Challenges and Innovations

Historically, large-scale kelp farming faced obstacles due to the lack of affordable and sustainable marine infrastructure. Collaborating with the University of British Columbia's materials engineers and bioproduct researchers, we developed **SeaBrick** and **Kelpstone**—high-strength, nontoxic structural composites made from seaweed biomass. **Kelpstone** is notably 3X stronger than concrete, offering a sustainable solution for marine infrastructure.

## Environmental and Socioeconomic Impacts

Kelp farms act as substantial carbon sinks and could help achieve Global Net Zero emissions, reversing pre-Industrial Revolution greenhouse gas levels. These farms not only sequester CO2 but also help reduce global atmospheric temperatures, deacidify the ocean, and create opportunities for coastal Indigenous communities and climate refugees.

Comprising about 40% sequestered CO2, **SeaBrick** and **Kelpstone** can replace traditional materials like concrete and steel, aiming to decarbonize the construction industry significantly. Cement alone contributes to 7-8% of global emissions annually.

## The Exponential Feedback Loop

Utilizing seaweed to create **SeaBrick** and then using **SeaBrick** to build more kelp farms establishes a productive feedback loop between kelp cultivation and farm production. This loop is economically viable and optimizes biomass efficiency, enhancing the reproduction rate and profitability of kelp farms.

## Potential and Viability

Unlike reforestation, open-ocean seaweed farming introduces a new carbon sink without displacing existing ecosystems. Expanding seaweed cultivation to between 100K and 1M square kilometers could enable humanity to reach Global Net Zero in 50 years and begin reversing climate change.

Factors contributing to our project's viability include the ocean's vast space, rapid kelp growth rates, deep ocean dynamics, CO2 solubility, desalination potential, and renewable energy sources like waves, wind, and solar. The economic value and versatility of seaweed in product development further enhance feasibility.

## Conclusion

Harnessing deep-water kelp farms for carbon sequestration presents a promising opportunity to combat climate change effectively. With innovative materials like **SeaBrick** and **Kelpstone** and a strategic approach to kelp cultivation, we aim to achieve Global Net Zero emissions and create a sustainable future for generations to come.
