Powered by Wind & Sun

Using our natural resources to combat pollution challenges.

Our SmogStop Pollution Barrier utilizes a double-walled structure that redirects traffic emissions into a channel. This channel creates wind vortexes and improves the vertical mixing of emissions with clean air. The photocatalytic coating that lines the inside of the walls utilizes sunlight to decompose nitrogen oxides (NOX) and volatile organic compounds (VOCs), transforming them into harmless gases and water.
