Gạch nổi cho phép xây dựng trên mặt nước

Canada-based company SeaBrick is developing algae-based bricks that could serve as foundations for floating structures in the sea.

With sea levels rising, many cities and even countries are at risk of being submerged. SeaBrick is aiming to build infrastructure on water thanks to environmentally friendly floating bricks, Interesting Engineering reported on February 22. SeaBrick bricks are described as a system that can be interlocked to form a platform, like Lego bricks. The company uses kelp from the ocean to make them float. Some other essential ingredients include red clay that covers 38% of the ocean floor and apricot algae, a large brown algae that often overgrown in coastal waters, causing trouble for local habitats.

While governments and NGOs spend a lot of time and money to get rid of algae, the use of SeaBrick bricks not only helps clean up these waters but also provides a source of income for affected communities. affected by them.

Production of kelp and apricot algae also helps sequester carbon from the atmosphere more than 20 times more efficiently than land-based forests. Compared to floating concrete structures, using SeaBrick bricks in construction is estimated to save 72% of costs, while generating less carbon emissions, according to Seasteading, the research institute set up to support construction build mobile communities on floating platforms in international waters. SeaBrick has partnered with Seasteading with a shared vision "to decarbonize the global construction sector, while supporting vulnerable coastal communities".

The founder of SeaBrick believes that using floating bricks made from kelp and apricot algae can help the planet permanently sequester millions of tons of CO2. In addition, this technology can also support green energy projects such as wind power plants, tidal power and offshore solar, helping us to transition from today's mining-based economy to one renewable economy, in which used kelp can be easily regenerated.
