Community Carbonates’ engineered flowstones
The project is piloting surfaces in New York that it says capture CO₂ from ambient air and turn it into solid carbonate on existing urban infrastructure.

- Urban building partners, climate educators, and curious visitors
- Worth noticing
- The Governors Island installation ran about a month; the site says harvested material was cast into a cement cylinder and 3D-printed into take-home pieces.
Field notes
The site distinguishes two New York deployments: a roughly month-long Governors Island run and a SolarOne installation launched in October 2026. It reports that material from the first was measured as high-purity, then cast into a cement cylinder and 3D-printed into take-home pieces, but provides no purity or capture quantity. SolarOne adds time-lapse imaging, pH and air-quality sensing, alongside a nine-educator workshop whose reported confidence scores rose from 2.8 to 4.2 out of 5.
