Self-Healing Planetary Crusts are infrastructure materials designed to autonomously repair structural cracks through a process known as bio-calcification, which involves the activation and activity of embedded dormant calcifying bacteria.
This technology addresses the challenges of maintaining structural integrity over long periods, especially in harsh environments where regular maintenance is difficult or impossible. It reduces the need for frequent repairs and replacements, extending the lifespan of infrastructure.
The technology works by incorporating dormant calcifying bacteria into large-scale concrete or ceramic mixes. When cracks form in these structures due to environmental stress or aging, the bacteria are activated by moisture and nutrients, leading to a process that fills the cracks with calcium carbonate, effectively healing them without human intervention.
Manufacturing involves creating a concrete or ceramic mix that includes dormant calcifying bacteria encapsulated within microcapsules to protect them during processing. The materials are then applied in large-scale construction projects.
The build process begins with the formulation and mixing of the self-healing material, followed by its application on-site. Once the structure is built, it can begin healing itself over time without additional maintenance.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Healing process requires minimal energy once initiated.
