Solar Punk

The University of Belgrade’s Institute for Multidisciplinary Research invented an urban photo-bioreactor. Liquid 3 cleans the air and serves as a bench in the Belgrade city centre.

It's a tank filled with microalgae, a solar panel on the top generates electricity for USB charging ports for citizens and a pump that pumps air into the tank where the algae process the CO² and produce Oxygen.

For those who want to know the source of this wonderful animation, this was made by the London-based The Line animation studio. The animation is called Dear Alice, and here's the original source with all the full credits. The score was made by a long-time Ghibli composer. The animation was made for a dairy commercial (and the dairy company seems to be as eco-friendly as is possible for a dairy company if it disappoints you the animation is made for an ad).

I found this on reddit's solarpunk.
