Repariring the Present // S+T+ARTS 2022 // CCCB


Reimagine public lighting in green urban areas

The project aims to reimagine the role of lighting in public urban spaces with a symbiotic relationship between the artificial and the natural world, focusing on a deeper understanding of the fundamental importance of nature as collaborator in the city.

The artwork consist in a light sculpture that can facilitate diferent tasks in order to create an autonomous and hybrid performative artwork based on a bacterium that produces electricity while decontaminating the soil.

Here below the essential points of interest:

- lighting
- soil decontamination 
- free energy / electricity
- rain water collection

Geo-Llum is conceived as an “organic” sculpture, where the role of humans is to take care of it, drawing attention to the diferent forces that play for its right functioning.
All the parts of Geo-Llum are interconnected and interdependent, gathering and collaborating to create a cycle of energy.

Geobacter metallireducens is a member of the Geobacteraceae, a family of Fe(III)-respiring Delta-proteobacteria that are of interest for their role in cycling of carbon and metals in aquatic sediments and subsurface environments as well as the bioremediation of organic- and metal-contaminated groundwater and the harvesting of electricity from complex organic matter.

This microbe is able to grow on metallic minerals or electrodes, generating electrical energy while eliminating certain pollutant from the soil and water, during its metabolisation.  

This living micro-organism will be insert in the soil in order to enhance the electricity produced in the bio-electro battery cell.


Geo-Llum is a light a light sculpture that would like to  improve the liveability of the city at night, contributing to create emotive atmosphere respecting all the biota, in order to avoid more light pollution.

We are using a design diversification method mixing diffent techniques and materials.
UP-CYCLING: Allowing an imaginative discovery around production fall-offs, manufacturing and recycling centres.
3D PRINTING with bio resins that minimise the harmful sediments in rain water collector and normal resin for the molding process for the final bronze outcome.

This is reason why we are taking in consideration the light parameters for the care of plants cycle and their pollinators as the wavelength, the color, the brightness and the plants photoperiod.

︎ Framework

Akasha Hub Barcelona is the project incubator and official partner.

The project will go hand in hand with Green City Lab during the first bio-remediation pilot program of Barcelona in Hort del Clot, a urban garden focused on ecology and social innovation.

The project is hosted by CCCB (Centro de Cultura Contemporanea de Barcelona), Sonar, UPC (Universidad Politecnica de Cataluña) thanks to S+T+ARTS Residencies.
