China has one of the worst pollution problems in the world. Currently, the air in China contains around nine times more the level of PM2.5 than is recommended by the World Health Organization. The population of China is putting themselves at risk every day just by walking outside. However, one man would like to put an end to this danger and change the air quality in China. The man in question is Daan Roosegaarde, who is a Rotterdam based artist, and the solution he has designed is a seven-meter tall tower that uses positive ionization to filter the pollution from the air.
As well as the tower and bicycle ideas, Roosegaarde and his team have also worked out how to make jewelry from the pollutants found in air. They have done this by condensing the dust that has been collected by the tower until it forms into tiny black stones which are then sealed into resin cubes and mounted onto various pieces of jewelry such as rings or cufflinks. They seem to be quite popular too and are currently selling for around 250 Euros per item.
