Vincent Callebaut has designed an anti-smog tower for Paris. The 3D's are far more successful than the elevations, but well worth a look for the techniques used.
'to filter air particles and harvest wind and solar power... The project is divided in two; a “Solar Drop” located on top of abandoned railway tracks and a “Wind tower”. The Solar Drop is designed to transform polluted into clean air through a system of filters covered with titanium dioxide which break the pollutant particles...The Wind Tower equipped with turbines in its entire façade produces enough energy for the neighborhood and houses a museum and learning center on renewable energies.'
