City Planning with Bright Bacteria

Renegade architect and futurist Rachel Armstrong has proposed that our cities, currently constructed of dead trees, baked mud, and refined ore, need to be coated in a layer of glowing, hungry bio-goo. Bioluminescent bacteria could be "painted" on walls, billboards, and sidewalks to provide a low-energy means to bathe city streets in a peaceful blue-green light.

Wild bioluminescent bacteria like Vibrio phosphoreum (pictured above) aren't bright enough to provide light to read by, but it's possible that they could be genetically engineered to produce more vibrant light. Of course, delivering nutrients to an entire city of blueish bacteria, especially ones that currently live only in water, could prove more of a challenge.

Armstrong also suggests that building surfaces could be fortified with carbon-hungry bacteria to soak up local C02 emissions. Even if hers is a decidedly sci-fi vision, it's vital to our planet's health (and our own) to push for over-the-top solutions. Breaking out of a 12,000 year old architectural paradigm will require thinking outside of the steel-and-concrete box.

Rachel Armstrong has previously been featured on Next Nature for her proposal to save Venice using protocells that grow and accrete like a coral reef. She will be presenting her views on synthetic biology at the Next Nature Power Show on November 5.

Ine Geevers: #YesNaturally was about co-evolution and partnership. How to become friends with o.a. bacteria, microbes and viruses. Because yes, they can be deadly and vital at the same time.
