Multiple turbines 5 are mounted, for example, on central reservations of motorways so that they are rotated by air movement caused by slipstreams of vehicles passing the turbines 5. When rotated by the wake effect of vehicles or natural wind, the turbines 5 generate electricity and create an anti down draft which sucks air, via ducting 1, 4, through a grill having organic filters, e.g. made of news paper, that collect carbon dioxide from polluting vehicles and/or traps smog. An automatic grill cleaner, a fire extinguisher 2, a pressure gauge 9 and a vortex release valve (5, fig 2) are also provided. The turbines 5 are provided with an aerofoil or rooftop paddle to maintain wind direction and are mounted on towers made of five used average car tyres (9) stacked on top of each other and reinforced with rods (10) and steel spurs with a bottom tyre filled with concrete (4) and the remaining filled with sand bags. The tyres act as a crash barrier and mitigate all vibrations. After use the filters are saturated in recycled vegetable oil and blown dry. |
