Shamengo pioneer Pierre Calleja has invented something truly remarkable--a light powered by algae that absorbs CO2 in the air--at the rate of 1 ton PER YEAR, or what a tree absorbs over its entire lifetime! The microalgae streetlamp has the potential to provide significantly cleaner air in urban areas and revolutionize the cityscape.
