Biomimicry Speculative Engineering for 2070

There is one single thing that would instantly transform and future-proof our city: the integration of living, vascular infrastructure.

Right now, cities treat infrastructure like a series of static, separate problems: water goes into concrete storm drains, electricity runs through rigid copper grids, and waste sits in static bins. By replacing this dead infrastructure with a unified vascular network, our city would stop operating like a machine and start functioning like a living organism.

By the year 2070, this shift will have completely rewritten the DNA of the modern metropolis!

The Transition From Concrete to Vascular

The transformation begins the moment city planners stop laying down rigid, impermeable materials and start installing biomimetic vascular pathways. Just like the blood vessels in our bodies or the veins in a leaf, these systems are flexible, self-healing, and multi-functional.

Self-Healing Fungal Utilities: Instead of burying rigid plastic and metal water pipes that crack during winter freezes, the city’s utility network is lined with a synthetic composite grown from “fungal mycelium.” When a crack forms due to shifting ground or freezing temperatures, the pressure triggers the material to secrete an organic binding agent. The pipe literally grows itself back together within hours, eliminating the need to tear up city streets for repairs.

Wetland Basements: To tackle chronic urban flooding, building foundations are retrofitted with porous materials modeled after mangrove roots and coastal wetlands. Instead of fighting water with concrete barriers, buildings are designed to drink it. During heavy rainstorms, the vascular foundations safely absorb excess water, filter it through integrated gravel-and-moss layers, and store it in underground cisterns to flush the building’s plumbing later.

Stomata Building Skins: To conquer the stifling summer heat, the exterior facades of skyscrapers are coated in a flexible material that mimics the stomata (microscopic breathing pores) of plant leaves. When temperatures spike, these microscopic pores open up, releasing tiny amounts of harvested rainwater as vapor. This mimics plant transpiration, actively sweating to cool the surrounding air by up to 10°F without running a single air-conditioning compressor.

The City in 2070

Walk down the street in 2070, and the city feels profoundly peaceful. The harsh glare of concrete is gone, replaced by textured, organic surfaces that absorb sound and weather gracefully. Roads no longer buckle from potholes because the pavement contains limestone-producing bacteria that automatically fill in cracks when it rains. The city no longer battles nature; it uses nature’s 3.8-billion-year-old blueprint to manage energy, water, and traffic seamlessly.

The Path Forward: Building 2070 Today

While the fully integrated vascular city of 2070 remains a future outlook, the work to build it cannot wait for the turn of the half-century—it must commence now. The 3.8-billion-year-old blueprints of nature are already sitting on our desks, and the raw technologies have already graduated from the lab.

Every time a city breaks ground on a new transit line, repaves a crumbling sidewalk, or updates its municipal building codes, it faces a choice: continue investing in the dead, rigid concrete of the past, or plant the seeds for a living infrastructure.

By treating today’s routine urban maintenance as the first evolutionary step toward a biological grid, we ensure that the resilient, breathing metropolis of 2070 isn’t just a speculative dream, but an inevitable reality!
