The street lamp that absorbs CO2 | Pierre Calleja | TEDxLausanneChange

http://www.tedxlausanne.org: 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.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations).
