biomA

Volumetric Fabrication Device for growing Organic Batteries

In 2052, the Open Tech society and Citizen Science movements in Sao Paulo, develop biomA, a volumetric fabrication protocol for producing organic batteries and supercapacitors using organic feeds like algae and chitosan biopolymers. This regenerative alternative aims to replace mineral mining for renewable energy infrastructure across distributed and federated Socially Useful Production fabrication networks. The system nurtures Cladophora algae to sequester carbon dioxide. Ultrasonic transducers levitate and position algae seeds precisely in a 3D point cloud. Chitosan binds the algae in each layer, while a UV laser cures the biopolymer, resulting in carbon-negative, regenerative batteries.

Biomineralisers are dual-purpose instruments, remediating water bodies polluted by centuries of mineral exploitation while cultivating rare-earth minerals. Paired with wastewater electrolysis and biochemical deposition, they provide a cost-effective solution for purging nitrates, phosphates, and heavy metals from soil and freshwater ecosystems. It is also deployed in processing sulphide and uranium ores, promising soil and water body remediation and influencing material cultures observed in the hi-TEK practises of the Masisi people. Despite modest yields, biomineralisers offer high-purity throughput, aligning with 22nd-century Slow Fabrication standards. Their invention has seen a whole new field of metallurgical practises called Symbio-metallurgy.

I conducted seawater electrolysis experiments based on Hilbertz' work but this time with a carbon substrate. I 3D printed a conductive graphite PLA filament and electroplated it with seawater to illustrate a carbon-negative coral sample.
