Architect Vincent Callebaut’s latest project balances public galleries, meeting rooms and gathering spaces over canals and abandoned railroad tracks in the 19th Parisian district. Callebaut describes the process as an intention to “absorb and recycle by photo-catalytic effect the cloud of harmful gases (Smog) from the intense traffic near Paris” [source: Inhabitat].

Definitely a worthy and proactive effort at going beyond the traditional green architecture.
