Traffic Makes the Algae Grow

Readers of the blog know that ABO has been pushing the EPA to include carbon capture and utilization among its approved pathways for emissions reductions goals for power plants.

The transportation sector is the second largest contributor to greenhouse gases (after power generation), responsible for about 32% of total U.S. CO2 emissions and 27% of total U.S. greenhouse gas emissions in 2012.

While it’s relatively easy to capture emissions from a stationary source, like a smokestack, it’s immeasurably harder to capture it from a mobile source – like a car. Or is it?

Sacre Bleu! This summer, as part of a festival in Geneva, the Dutch and French design firm Cloud Collective built an algae farm on an overpass. The algae were fed by CO2 emissions from passing vehicles below and on sunlight from above.

Check out this video – a beautiful design and ingenious integration into the built environment.  At 1:50 into the video, check out the movement of algae – it looks like the traffic below!

As much as the design was reflective of the potential of algae, it’s also yet another sign of how algae technology inspires researchers, engineers, entrepreneurs and artists around the world.
