Sargablock: Bricks from Seaweed
In short: sargassum seaweed is washed onto shores anyway, why not use it to make bricks? They form the bricks using a standard block-making machine, dry them at the sun, build small houses out of these, and plan to <i>donate</i> these houses to local families in need.<p>They say that they use 40% of seaweed in the bricks, and 60% is "other organic material". I wonder what material is this.<p>I also wonder how well the sargassum bricks withstand weather.
