In the early nineties, Pierre Calleja started doing researching aquaculture. A few years later he sold his first start-up and went on to do research on microalgae. These microscopic unicellular plants are of huge importance for our planet as they absorb large amounts of CO2 and produce roughly half of our atmosphere’s oxygen.
Using micro-algae, Pierre Calleja has prototyped a lamp that does not only emit zero CO2, it actually absorbs massive amounts. In the future, these lamps could be used to illuminate our streets, parks and homes.
