French Bio Chemist Pierre Calleja discovered that Micro Algae eats CO2 – i.e. car exhaust – and then uses that energy power to create light. This technology was recently tested in a parking lot to clean air – it can capture and filter one ton of CO2 per year – and used the pollution as an energy source to create light. This technology is currently being used to light and filter the air in an underground parking garage, but this would work great in urban areas, and revolutionize cityscapes.
