Biosolar panels made of algae reduce CO2

Scientists from Imperial College London have partnered with the start-up Arborea to develop an algae-based cultivation system that filters harmful substances out of the air. Known as the "BioSolar Leaf", the system is based on microalgae, phytoplankton and diatoms that grow on solar panel-like structures. The algae reduce carbon dioxide in the air through photosynthesis and produce oxygen at a rate equivalent to a hundred trees from the surface area of just a single tree. Arborea uses the resulting biomass to extract nutritious food additives for plant-based food products.
