An air-purifying billboard has been erected in Leicester Square in London, England.
Designed by Italian eco-technology firm Anemotech, the billboard uses nano-molecules to remove particulates, nitrous oxides, and sulphur oxides from the air. The billboard is said to have a cleaning radius of 260 square feet and is expected to reverse the emissions effect of more than 13,000 cars per year, European Cleaning Journal reports.
