Ma house is a splicable floating module that uses microalgae photosynthesis to remove carbon from seawater and the atmosphere. It improves the problem of offshore acidification caused by excessive carbon dioxide concentration, and then protects the survival of calcium carbonate shell marine organisms such as corals and shellfish. When the organism is running, the external seawater and air are drawn in to mix it with the microalgae, so that the microalgae use the seawater and the carbon dioxide in the air for photosynthetic growth, and finally produce oxygen and discharge it into the atmosphere; the reacted seawater is then filtered and Centrifugation leaves the microalgae and drains them out of the seawater, and the overgrown microalgae can be extracted and made into algae products and biomass fuels, forming a circular ecology of energy.
